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.

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.

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.

Installation: Direct replacement. Installation is performed exactly like the installation of a stock clutch.

Heavy-duty throw out bearing mounted on a movable bushing to find center every time the clutch is disengaged increasing the life of both the clutch and throw out bearing itself.

Spec Flywheels
SPEC billet steel and billet aluminum flywheels are recommended as are placement for OEM cast steel flywheels in street high performance and racing applications. Your engine, gearing and vehicle weight are factors in determining which flywheel would be best suited for your application. Please inquire with a FTPP technical assistant for recommendations.

BILLET ALUMINUM
SPEC billet aluminum flywheels are also CNC machined and exceed SFI standards for high stress racing applications. These units are recommended for highly modified street or racing vehicles, and for mildly modified street cars that can benefit from reduced rotating mass without the loss of daily drivability.  Consult a SPEC technical assistant for recommendations on your specific needs.  The body of the flywheel is made of tempered aluminums, either 6061 T6 or 2024 T3, for ultimate strength and lightest possible weight. The 1/4 inch thick
friction plate is a 1050 high carbon alloy, for incredible durability with any friction disc material, even iron. The plates are secured to the body by aerospace fasteners or stainless steel rivets, depending on the application. These fasteners were chosen because of their exceptional strength and corrosion resistance.  The ring gears are pressed on and secured with grade 10 fasteners. They gear is also heat treated for longevity. They are effective, durable and almost too pretty to install.!
