GENERAL TABLE OF CONTENTS ected max TABLE OF CONTENTS a Tradition of Excellence

1938 — The path to becoming gear technology

leaders begins when Borg Warner launches its

Warner Gear division in our Auburn, Indiana, plant.

1950s —Warner Gear becomes the largest

independent producer of construction and

automotive transmission gears, right-angle gear

boxes and in-board pleasure boat marine gears.

1961 — Warner Gear develops a limited-slip

differential for automotive aftermarket applications.

1968 — Warner Gear patents a wheel-mounted

hydrostatic drive and launches it under the Power

Wheel® brand.

1982 — George Callas buys the Warner Gear

division and renames the, now, privately held

company Auburn Gear.

ECTED Max™ Advantages

• Gearing is made from aircraft quality, 9310 heat treated billet steel to make it tough, durable and reliable.

• Switchthelockeronoroff“on-the-fly,”atmoderate road speeds [with all 4 wheels on the ground].

• No need for shift forks or pins that must be lined up to obtain locker mode.

• Noisy lockers, not here. ECTED Max is quiet.

• Backed by a one-year warranty, plus the industry-exclusive D-REX (new differential exchange) program. See page 31&32 for details.

• ECTED Max can be used in front axle applications, with or without lockout hubs. [IMPORTANT NOTE: ECTED Max is NOT recommended for use with front axles that feature an “inter-axle disconnect.”]

The science behind the superiorityThe ECTED Max is a selectable

traction device. An ON/OFF switch

is mounted near the driver. When

“OFF”, the clutch pack (7), located

behind the side gear (6), activates

the limited-slip mode. As torque

increases, the separating forces

within the differential gears increases,

causing the clutch pack to be

compressed, providing bias torque

to the high traction wheel. When

selected “on”, current is sent to the

electromagnetic coil (8). The coil is

retainedbyaclipthatfitsoverone

Go Anywhere With the Only 2-in-1 Performance Traction Differential It’s Limited-Slip Plus the Power of a Selectable Full-Locker! The ECTED Max is a traction technology product that puts a selectable full-locker or limited-slip operationalmoderightatyourfingertips.

Shifton-the-flywithjusttheflipofaswitch, and go from high-performance traction control to a full-locker mode that delivers 100 percent torque transfer to both wheels for extreme-duty off-roading and high performance drag racing.

The ECTED Max enhances 2-WD mobility unlike any other performance traction differential on the market, while making 4-WD vehicles virtually unstoppable. ECTED Max is ideal for street-strip use. Limited-slip traction for street and full-locker performance for the strip in one differential. Ideal for 4-WD vehicles that are used both on and off-road.

The auburn Differential Advantage Is SimpleHere’s an equally simple chart to prove it. No other locker offers limited-slip capabilities when switched off.

Everything you need for installation of the ECTED Max come in one box—the unit, wiring harness, Auburn limited-slip additive and instructions.

of the bearing cap bolts, making it

non-rotational. The coil rides on a

ball bearing (9). The ball bearings

spin with the differential case (10).

The coil creates a magnetic

fluxsothatthepilotcone(1)is

pulled into engagement with the

differential case (10). This frictional

engagement causes the bearing

balls (2) to ride up on a ramp

machined into the side gear (3).

This radial travel of the balls (2) also

causes lateral movement of the

side gear (3). The lateral movement

of the side gear (3) applies a force

onto the center block (4). The center

block (4) has an elongated hole

Electronically Controlled Traction Enhancing Differential

RACE

Performace Limited-slip differentials More Traction, lighting-fast action. Unleash your vehicle's true performance. Let’s cut to the traction. The Auburn Gear high-bias torque Pro Series, High Performance and Race Series limited-slip differentials out perform virtually every standard OEM differential.

To really see and feel what your vehicle can do, Auburn Gear diffs effectively andefficientlytransferyourpowerto the wheels. Auburn diffs deliver usable traction and faster engagement for controlled power transfer and lightning-fast reaction to changing road conditions.

No matter what your application—performance or passenger, light or heavy, on- or off-road—Auburn Gear limited-slip differentials are engineered to provide smooth torque-sensing operation and durable, dependable performance.

AuburnGear’sflagshiplimited-slipdifferential gives you smooth torque-sensing operation with the correct bias ratios to out perform the competition.

Turns your torque up another notch, offering an even higher bias ratio and faster sensing reaction than HP for the very best in controlled power transfer.

Auburn Gear has developed, tested and is making available a racing differential for the 7 5/8 Firebird/Camaro, original gear ratio of 3.23 and up, with 28 axle spline. We’ve also developed, tested and are making available a racing differential for Ford 8.8, all ratios, and 28-axle spline.

Why Auburn gear limited-slip differentials?

The Auburn Gear limited-slip differential

employs an integral cone clutch side

gear unit that creates friction with the

carrier to drive both tires. The highly

efficienttorquetransfercapabilityof

the Auburn Gear limited-slip differential

is achieved through the use of cone

clutches coupled to beveled side gears.

As torque is transmitted through the

differential side gears to the axle

shafts, the side gear separating

forcesandspringpre-loadfirmly

seat the cones into the differential

case. The cone design, along

with the applied force, determines

the torque transfer capability

of the differential. When torque

levels decrease, as in a cornering

Auburn Gear Pro Series and High Performance

Series differentials provide superior performance

through a unique cone-clutch design that transfers

more power to the high-traction wheel for quick

acceleration and tight cornering.

Comes down to the cone and cup design

maneuver, the gear separating

forces also decrease, allowing

the axle shafts to rotate

independently. This unequally

divides the torque between the

two wheels, delivering more

torque (bias torque) to the wheel

with the most traction.

SPECIAL NOTE: Stock bearings are usually LM603049/LM603012 for the ring gear side and LM501349/LM501314 for the opposite side. Some use LM501349/LM501314 for both sides. The Auburn limited-slip differential will fit in either application. We supply 2 sets of LM102949/

LM102911. Axles that have the LM603049/LM603012 bearing will still use that bearing, but the opposite side will require the LM102949/LM102911 that is included with the differential.

Auburn Gear, Inc. has developed a performance limited-slip differential specifically for road racing—a differential case designed to allow the center pin to float along with the axle shafts. This design feature aids the driver when cornering, so that when the driver is turning, the outside wheel axle shaft will apply a force to the center pin, hence, the pinion gears will firmly seat the inside cone/side gear assembly giving the racer an extremely “tight” rear axle. The greater the G-force the more bite you get! If you are an avid road racer you’ll want this unit.

Every effort has been made to ensure accuracy of the contents of this catalog. However, we assume no responsibility for errors or omissions.

D-REX stands for Differential-Replacement Exchange Program. Auburn Gear's limited-slip differentials are designed and manufactured with a robust and unique cone clutch mechanism. However, due to machining and assembly processes, the differential case and side gear/cone clutch mechanism are a matched set and therefore non-rebuildable. All other components within the Auburn Gear differential are replaceable and service kits are available. In order to address the non-rebuildable components within our limited-slip differentials we offer the D-REX unit.

What it is

What we promiseWith Auburn Gear, you get a full one-year manufacturer's warranty, plus D-REX coverage for four years from date of purchase.

DiFFERENTiAL REPLACEMENT EXCHANGE PROGRAM

Qualifications for D-REX Program


The Auburn Gear limited-slip differential and ECTED Max selectable locker designs have been extensively tested with high-quality Non-Synthetic 80W 90 hypoid oils treated with limited-slip friction additive. Three (3) oz. of Auburn Gear additive (part #504102) will treat one (1) quart of oil. To avoid differential clutch chatter (noise) and for optimum performance, use the oil and additive described above. Use of other additive and oil types may cause differential clutch chatter. We do not recommend synthetic oil. Auburn limited-slip additive (a 6 oz. bottle) is packed in every box with the differential. Auburn limited-slip additive is available at your local authorized Auburn distributor.

To qualify, the unit must have been purchased within the last four (4) years. This can be determined either from you original dated receipt OR by the date code stamped on te differential case. Example: 018 A20 12. 018 represents the part number. A20 represents the month and day (January 20). 12 represents the year (2012).

Contact your distributor or Auburn Gear to get your Replacement Exchange Number. Do not return your unit without getting this number. Units received without the RE# will be returned to sender.

Do not return the differential with bearings and/or ring gear installed. Auburn Gear will not be held responsible for products returned with these components installed. They will be scrapped.

RESOuRCES



GENERAL QuESTiONSQ1. What are the differences between the High Performance LSD, the Pro LSD, and ECTED Max?A1. The ECTED Max is a limited-slip and a locker in one differential. The driver controls the mode with a switch inside the

vehicle. The ECTED Max can be switched to lock mode, which allows 100% torque transfer to both wheels. The High Performance and Pro are limited-slip units. Any limited-slip differential can allow the low traction wheel to spin since the amount of torque that can be transferred to the opposite wheel is limited (hence the name limited-slip).

Q2. What is the difference between the Pro Series and the High Performance Series?A2. The High Performance Series is another option in the Auburn traction enhancement products. The cone clutch design

offers increased durability and performance in normal street use. The high bias cone clutch design of the Pro Series provides a higher torque and preload, making it the ultimate limited-slip differential for true performance. It is engineered to provide lightning-quick, torque-sensing traction when you need it. No buttons to push, no leavers to pull, it goes into action when you accelerate. It handles superbly—on and off road.

Q3. Is the ECTED Max and/or limited-slip only for Jeeps/trucks/SUV's, or can it be installed in a car?A3. Auburn differentials are suitable for virtually all vehicle applications where additional traction is needed— for recreational,

sport or work use. For example, installing an Auburn differential in your performance car will give you spool-like performance when coming off the line, combined with full wheel differentiation when turning. Imagine two wheels gripping the pavement instead of one spinning effortlessly.

Q4. What differential should be used for Drag Racing?A4. For true street-strip performance, the ECTED Max is the best application. The ECTED Max is really two differentials in

one.Itisafull-timelimited-slipdifferential,thenwiththeflipofaswitch,itconvertstoafull-locker.Thebestofbothworlds and winning at the track. In the limited-slip product line, for both street and strip, the Pro Series is the choice; however, the High Performance limited-slip is effective in street and strip applications. For strictly drag racing (no street driving), a spool would be the choice.

Q5. How much horsepower and torque will the High Performance LSD take? Is there a horsepower limitation? What is it?

A5. Each size has it's own limitations, but it is more related to torque than to horsepower. Additionally, the transmission type, driving habits (snap starts) and tires (traction) play a role.

Q6. How can I determine if a traction device such as a positraction or locker is installed in my vehicle?A6.Putthetransmissioninneutralandjackupbothtires.Rotateonetire.Iftheothertirespinsintheoppositedirection,

you have an open differential. If it spins the same direction, you do have a traction device.

Q7. If only installing one traction differential, should I install in the front or rear?A7. A rear locker can greatly increase the mobility of the vehicle. In many scenarios, a 4 X 2 with a rear locker can outperform

a 4 X 4 without a locker. For severe traction applications and extreme off-road, the ECTED Max electronic locker with limited-slip differential is an excellent choice.

Q8. What is clutch chatter?A8. Clutch chatter occurs when the clutch cone engages and disengages rapidly in the differential case. It causes no

damageandcanbecuredbyusingthecorrectoilandfrictionmodifies.Clutchchatteriscausedbythedifferencebetweenthestatic(non-slipping)frictioncoefficientandthedynamic(slipping)frictioncoefficient.Whenthedifferencebecomes too great, the clutch cone cycles between the two (sticking and slipping), which creates the noise. Friction modifiersbringthestaticanddynamicfrictioncoefficientsclosertogethertominimizechatter.AuburnrecommendsusingAuburn limited-slip additive (#504102) with a high-quality non-synthetic 80W 90 hypoid oli.

Q9. What is a cone clutch?A9. The Auburn Gear limited-slip differential employs an integral cone clutch side gear unit that creates friction with the

carrier to drive both tires. The cone clutch design consists of two clutching members, one internal and one external (see image on page 9). The internal member is a unique single tapered part with lubrication grooves, attached to the side gear, creating the cone clutch assembly. The external member is also tapered with a matching angle. When the two are forced together, torque is transferred from one member to another. The cone clutch design allows for more clutch capacity in the same space and is less likely to chatter due to the reduced number of sliding surfaces. This means higher torque transfer for better traction, without the noise.

Q10. Can I use the stock bearings?A10. Yes. Exceptions are Ford 8", Ford 9" (some housings) and Dana 35. GM 8.5/8.6 may require special bearings when

installing an ECTED Max in a pre 1999 vehicle. Bearings that should be used with the Auburn Ford 8” and 9” differentials are determined by the bearing bore size. Small bearing bore 2.8 use bearings LM102949 & LM102910. Bore 3.062 use bearings LM603049 & LM603011. Bore 3.25 use spool only. Refer to the application pages for bearing part numbers.

Q11. Does Auburn have a limited-slip additive?A11. Yes. Auburn Gear limited-slip additive, part #504102. Use for both ECTED Max and limited-slip differentials.

It is available at your authorized Auburn distributor.

EFFECTS OF AuBuRN DiFFERENTiALSQ12. Will the driving characteristics of my vehicle change?A12. For rear axle applications, any change will be minimal and usually unnoticeable. The operation of limited-slip differentials

will be quiet, smooth and seamless. With front axle installations, there may be a slight addition to steering effort.

Q13. Are the ECTED Max and limited-slip differentials noisy?A13. No. Operation is quiet and seamless with properly maintained lubricant and limited-slip additive. There is no clicking

or banging.

Q14. How do Auburn differentials handle on slippery roads?A14. Any traction can affect handling on slippery roads. If the traction is overpowered by the driver, both wheels have lost

tractioninsteadofjustone,whichcouldcausealossofside-to-sidestability.

Q15. Can I tow my vehicle if it has an ECTED Max and/or limited-slip?A15. Yes. If the unit is installed in the front, it is recommended to unlock the front wheel hubs and/or place the transfer case

in 2-wheel drive.

Q16. What affect will Auburn differentials have on my towing capability?A16.TheECTEDMaxandthelimited-slipdifferentialswillnotnegativelyaffecttrailertowing.Infact,youwillfindmajor

improvementintraction.Itwillbebeneficialwhenpullingtheboatuptheramp,towingacamperonunpavedroads or anytime where increased traction is important.

Q17. Does the Auburn limited-slip differential affect gas mileage?A17. This would be negligible typically. However, an Auburn limited-slip usually weighs more than an OE differential and

since the clutches slip during turns, some energy loss does occur.

TiRESQ18. Will tire pressure affect the operation of the differential?A18. Mismatched pressures mean different tire diameters and different wheel speeds. Keep the tire-rolling radius

(with air pressure) within 1/4" for on-road vehicles and 1/2" for off-road vehicles.

FREQuENTLY ASKED QuESTiONS



Q19. What size tire (diameter) can I use with Auburn Gear differentials?A19. Refer to the recommended tire size on page 35 of the catalog.

Q20. Is tire wear affected by limited-slip differentials?A20. No. Auburn Gear differentials provide full wheel differentiation when turning so tire wear is minimized.

Q21. Will I get tire hop or chirp with the ECTED Max or limited-slip differential?A21. It depends on the vehicle set-up and the tires. Typically, both the High Performance Series and Pro Series will

accommodate turns on clean, dry pavement without wheel hop or tire chirp. In the "off" or limited-slip mode, the ECTED Max will accommodate turns on clean, dry pavement without wheel hop or tire chirp. In the full-locker mode (which should be used for severe off-road or drag strip performance) you may experience some wheel hop.

MAiNTENANCE AND WARRANTYQ22. What maintenance is required after an ECTED Max and/or limited-slip is installed?A22.Werecommendyouchangethedifferentialoilaccordingtoyourvehiclemanufacturer'sspecificationsandtreatwithAuburn limited-slip additive (part numer #504102).

Q23. What kind of oil should be used with an Auburn limited-slip differential/ Auburn ECTED Max differential?A23. Non-synthetic 80w90 GL-5 oil treated with Auburn Gear friction additive, part #504102 (also known as a friction

modifier).SeeCatalogpage32.Three(3)ouncesofadditivewilltreatonequartofoil.GMorFordlimited-slipadditive may be used. We do not recommend synthetic oil. Auburn limited-slip additive is packed in every box with the differential.

Q24. Can Auburn Gear differentials be rebuilt? Can I repair the Auburn Gear limited-slip differential?A24.Newunits—notrebuilt—areprovidedataminimalcostforqualifiedreplacementsundertheD-REXprogram.With

the best warranty in the industry, there is no need to repair the Auburn Gear limited-slip differential. Please see the the D-REX new replacement program and limited warranty on pages 33 and 34.

Q25. Is there a way to tell if I have weak springs in my limited-slip?A25.AuburnGearlimited-slipspringswillnotweaken.Thespringsarenotsubjecttocycliccompression/expansion,which

can cause load loss. However, the clutch capacity can be reduced due to wear or damage from misuse.

Q26. What is the life expectancy of Auburn differentials?A26. As with all performance products, the application and driver skills dictate the life of the product. Long life can be

expected with all Auburn products when operated properly. Forcing one wheel to spin with respect to the other will greatly degrade the life of the differential.

Q27. What is the D-REX Replacement Exchange Program?A27. Auburn Gear differentials, because of the precision design and machining, cannot be rebuilt. Under the D-REX Program,

a NEW unit can be purchased for about the price of a competitor’s clutch pack. The D-REX program covers four (4) years from the date code or four (4) years from original purchase receipt. See page 33 in the catalog.

iNSTALLATiONQ28. Can I install an Auburn differential myself?A28. Auburn Gear provides detailed differential installation instructions to allow an experienced mechanic to properly install

the product. See page 34. Visit www.auburngear.com for copies.

Q29. What kind of break-in is required?A29. All Auburn Gear differentials go through a break-in cycle at the factory, so no customer break-in procedure is required.

Q30. Should I install traction differentials in front and rear?A30. It's a matter of personal preference, money and traction requirements. A single traction differential will usually double the

vehicles off-road ability. Installation of traction differentials in front and rear increases traction to the maximum. Always consider safety and your driving conditions when making your decision.

Q31. Can I install Auburn Gear ECTED Max and/or limited-slip differential in a 2-WD vehicle?A31. Yes. Traction improvement in a 2-WD vehicle provides the same traction improvement to the rear axle as installation

in a 4-WD vehicle.

Q32. Can I install an ECTED Max and/or limited-slip differential in the front and rear of a 4-WD?A32. Yes, if the application is available. However, we do not recommend installing a unit in the front differential if the vehicle

has a full-time 4-WD and is primarily used on the pavement.

ECTED MAXQ33. Can I repair the ECTED Max if I need to?A33. Yes. Depending upon your needs, several types of service kits are available. The gear service kit, locking mechanism kit,

starter/amateur kit and the universal wiring kit. Please review the Auburn Gear D-REX warranty as it provides the best warranty in the industry.

Q34. Can the ECTED Max be used in the front axles?A34. ECTED Max should not be used in front axles that have an inter-axle disconnect. On manual hub applications,

both hubs are to be locked or unlocked. Do not lock one side and not the other. Differential damage can occur.

Q35. Can the ECTED Max be engaged on-the-fly?A35. Yes, at reasonable speeds. The wheel speed difference between the wheels should be below 50 RPM to prevent

impact loads to the drivetrain. It is recommended that the ECTED Max not be engaged if one wheel is completely off the ground or pavement.

Q36. How is the ECTED Max activated?A36. The ECTED Max is activated by turning on the mounted switch inside the vehicle. When off, the limited-slip function

responds automatically when torque is applied.

Q37. Is a relay necessary for ECTED Max operation?A37. The ECTED Max switch is more than capable of managing the current that the ECTED Max requires. No need

for a relay.

Q38. Can I purchase the wiring harness for the ECTED Max?A38.Yes,thewiringharnessisuniversaltofitanyvehicle,andcanbepurchasedseparately.Refertocatalogpage32

for ECTED Max service kits or visit www.auburngear.com.

Q39. Is the ECTED Max and/or limited-slip streetable?A39. All Auburn Gear differentials are very streetable. Both the ECTED Max and the limited-slip provide smooth, quiet

operation.Infact,AuburnGeardifferentialswereusedasoriginalequipmentinthefirstmusclecars.Plus,theyare aggressive enough to be used in other performance applications. When the ECTED Max is in full-locker mode, you may experience some under or push steering.
