If you are installing a new set of gears in your 1982-2001 10-bolt rearend, you will need a master install kit. The kit includes new pinion bearings, carrier bearings, crush collar, gasket and silicone sealant, everything needed for bolting in a new gear set. You can also use this kit if you're just looking to rebuild the rear in your car or truck. This 7.5"/7.625" series differential can be found under many GM cars and trucks.

If you installed a set of aftermarket gears in your 1993-2001 Camaro, Firebird, or Impala SS you will need to re-calibrate your speedometer. SLP has just released a new processor that allows you to do this, which will make speedometer re-calibration a snap. This new Re-calibrator is endlessly adjustable, so if you make any gear or tire height changes in the future, you can flip a few switches and once again have accurate speedometer readings. Simply splice the re-calibrator into your vehicles wiring harness. Detailed installation instructions included.

GM has designed your car's traction control system to activate as soon as you start the car, but sometimes it's just not necessary. SLP has come up with a new little device that actually reverses the activation of your car's TCS function, by not having the system activate until you turn the manual switch on located on your car’s dash or console. No more embarrassing or annoying moments at the track. Installation couldn’t be easier, since this device is a simple plug-in.

Auburn Performance Unit
Auburn Pro Series Unit $

Auburn Gear's high bias Pro Series and High Performance Series limited-slip differentials outperform standard OEM differentials hands down. They deliver more traction and faster engagement for controlled power transfer and lightning-fast reaction to changing load conditions. The Auburn Gear limited-slip differential is engineered to provide smooth torque-sensing operation with bias ratios to meet your performance needs. This superior performance is achieved through an innovative cone clutch design which transfers more power to the high-traction wheel for quick acceleration and tight cornering. Both units are compatible with ABS and TCS.
