Performance Differentials 

Winning on the street. Conquering off-road terrain. Hauling big-time truck loads. 

That’s what performance differentials are all about. Auburn Gear has manufactured and supplied aftermarket differentials for more than 60 years, making us a leading differential manufacturer in the U.S

Through extensive enginuity and listening to our customers, our team of engineers cracked the code to manufacturing differentials with superior traction, durability, and performance optimization. 

Our product offerings include top-of-the-line limited-slip differentials with our unique cone clutch differential design, an exclusive two-in-one electric locker differential, and an automatic locker that’s an excellent entry point for 2WD and 4WD vehicles that are new to the differential world. Meet our performance differential lineup to find the one that’s best for your specific needs.

High Performance

  • Auburn Gear’s flagship limited-slip differential gives you smooth torque-sensing operation with the correct bias ratios to outperform the competition.
  • Superior performance through a unique cone-clutch design that transfers more power to the high-traction wheel for quick acceleration and tight cornering.
  • Provides maximum amount of torque transfer without compromising the performance requirements of a vehicle in situations where torque transfer is required.

Pro Series

  • 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.
  • High torque bias cone clutch design provides maximum torque transfer, making it the ultimate limited slip differential for true performance.

Race Series

  • Performance racing limited-slip differential developed specifically for road racing.
  • Race design features benefit drivers by giving the racer an extremely tight rear axle when cornering.
  • Superior performance through a unique cone-clutch design that transfers more power to the high-traction wheel for quick acceleration and tight cornering.

Select-A-Loc™ Electronic Locking Differential

  • Select-A-Loc is a one-of-a-kind electronically controlled differential that allows you to go from a high-performance limited-slip traction control capability to a full-locker mode with just the flip of a switch.
  • Gearing is made from aircraft quality, 9310 heat-treated billet steel to make it tough, durable and reliable.
  • Switch the locker on or off “on-the-fly,” at moderate 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.
  • Select-A-Loc can be used in front axle applications, with or without lockout hubs. (NOT recommended for use with front axles that feature an “inter-axle disconnect”.)
  • Gives you the best of both worlds, a Limited-Slip Differential and Full Locking Unit.

Max Lock Locker

  • Max Lock is a fully automatic locker providing both 4WDs and 2WDs with optimized traction–all the time, even in the most unforgiving conditions.
  • Provides engine torque to the wheels with the most traction.
  • While traveling straight it locks the axles together. In a turn, Max Lock allows the outside wheel to rotate faster to complete the turn.
  • The best alternative for obtaining high traction whether you’re on the street, strip, track, on, or off-road.
  • Excellent entry point for enthusiasts looking for a simple and inexpensive way to significantly beef-up performance.

Find Your Performance Differential  

This is what it boils down to – where the traction meets the road, track, rocks, mud and dirt. For more than 70 years, high-performance street and off-road enthusiasts have looked to Auburn Gear for enhanced traction capabilities that go beyond OE standards for differential products. We never cut corners on the quality of your performance differential; every Auburn Gear diff is made from heavy duty, high impact military grade materials. Just as important, almost every Auburn Gear product is manufactured in America.

Use our differential finder to see which performance differentials work with your vehicle make and model. Then, find a distributor near you to get your hands on your new Auburn Gear differential.
