Eaton's premium performance results from a superior design. Carbon fiction discs, located behind each side gear, are pre-loaded with a central spring assembly. The spring force, combined with the pinion/side gear reaction forces, increases the clamp load on the carbon discs as input torque increases. This balanced design ensures that the bias torque of the differential is proportional to the input torque for smoother engagement.

Gear strength is crucial to high performance racing and off-road applications. Eaton engineers turned to state-of-the-art computer design tools to develop robust gears that can stand up to a lifetime of punishment. Eaton precision-forged gears are designed to mesh perfectly, providing improved strength and durability over the standard cut gear.

The Posi performance differentials feature a patented carbon friction material designed to endure the hostile extremes of Formula One racing brakes and clutches. Made from high temperature carbon fiber wrapped with a carbon anti-wear coating, these virtually indestructible discs thrive on repeated harsh engagements and thermal abuse, without performance loss. The fabric maintains its lubricity - to provide smooth, quiet operation over the life of the vehicle.

Auburn Gear's high bias 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 conditions. No matter what your application - the LSD 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. The high performance series is an excellent replacement for the standard original equipment differential for quality traction enhancement. The Auburn cone clutch design offers increased durability and performance in normal street use.

Installation: Installing a new differential is a fairly demanding job that requires close attention to tolerances and pre-loads. Comes complete with detailed installation instructions.

Tech Notes: Accepts tone ring for ABS applications. GM 7-5/8 applications use (2) different tone wheels depending on the differential case series.

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. The Pro series provide greater torque and preload, making it the ultimate LSD for outstanding performance. No buttons to push, no levers to pull, it merely goes into action when required. It also handles superbly whether on or off the road!

With the Powertrax No-Slip Traction System, you can unleash your performance vehicle's maximum power or give your Truck or SUV the ability to get you just about anywhere. Whether you want the added safety of high traction for everyday street use or extreme traction for the most demanding applications, the No-Slip advantage is just a simple upgrade away. Precision synchronization control provides exceptionally smooth and quiet operation. There are no friction clutches to wear out and no special lubricants required. Easily converts your open, limited slip, or locking differential for superior traction output.

Installation: The Powertrax No-Slip Traction System can be easily installed in your existing differential case without requiring special tools or setup equipment. Only basic mechanical skills are required. The Installation Guide provides easy to follow, step-by-step, fully illustrated instructions to help make the installation straightforward. Be sure to follow all instructions and heed all precautions. The ease of installation will vary depending on your differential type. Review the Installation Guide before starting to become comfortable with the procedure and to insure a successful installation.

Tech Notes: All Powertrax systems carry a 2-year manufacturer warranty on defects/workmanship.  Limited slip and open differentials require different part numbers. It is very important to know which type differential you have in order to get the correct part!

This mini spool is constructed of steel. Mini spools lock your axle together and are for strip and track applications only.

One of the best ways to improve your car's acceleration is to lower your rear-axle ratio. SLP offers 3.42:1, 3.73:1, and 4.10:1 ratios for the GM 7.5" and 7.625" differentials, which are found in 1993-2002 F-Bodies and in some S-series trucks. These gears are manufactured to OEM specs and tolerances, ensuring both long life and quiet operation. Available as a ring-and-pinion set only or in "kit" form, with a Zexel Torsen differential and an aluminum cooling cover.

If you need a clutch for your everyday driver, this is the clutch for you. RAM clutch sets are the first choice of professional installers because each set contains the correct, top quality replacement parts to ensure proper fit and operation in your vehicle. Every RAM premium clutch set is backed by our five year/50,000 mile limited warranty.

RAM Powergrip clutches are a heavy duty upgrade for street use and an option for increased service life in commercial applications. These sets feature composite organic, metallic, and kevlar friction materials matched for the specific application to allow retention of OEM pressure plates where necessary and compatibility with OEM release systems. Each set includes an OEM or better pressure plate, Powergrip disc, release bearing, and alignment tool. Because the Powergrip disc provides increased holding power by using a higher coefficient of friction material, some chatter may occur.

Matched disc designed to work specifically with the Centerforce Stage I and Stage II Pressure Plates.

Offers 30% more holding capacity than a stock original equipment clutch while still maintaining a stock pedal feel. Recommended as the finest quality upgrade from the OEM clutch.

Installation: Direct replacement. Installation is performed exactly like the installation of a stock clutch.
Tech Notes: Pressure plate only. Clutch disc is sold separately.

Generates up to a 90% increase in holding capacity over stock systems. This clutch/disc set is designed for use with engines producing high horsepower and torque, and any radically altered high performance street vehicles. All Centerforce clutch systems provide smooth engagement and light pedal pressure without compromising high performance.
