The DXD Racing Stage 2 Clutch Upgrade is perfect for those who have modified their engines for more horsepower and torque, and are beginning to see the limitations in the stock units. Offered in specific configurations of Daily, Endurance or Drag, the DXD Stage 2 is perfectly matched to your driving style and your specific use. Each Stage 2 Clutch is engineered to specifically support engine modification with increased clamp load and different material choices across the individual Stage 2 configurations. Each configuration includes all of the benefits of a DXD Racing Stage 1 Clutch Upgrade but also includes additional benefits specific to each.
This Heavy Duty Pressure Plate has an increased clamp load with little or no increase in pedal pressure. The Organic disc material has a high metal content that increases the co-efficient of friction by two times over a stock lining and increases rotational strength up to a 12,000 RPM burst point. This clutch system maintains a stock feel while offering strength and durability.
Recommended usage is daily, street and moderate race.
Which clutch is right for me?
The Daily configuration is focused around an OEM pedal feel and initial engagement characteristics. This is the clutch that won’t give you a significantly stronger left leg but will provide many thousands of miles of ease of use and operation with the ability to transfer engine performance to the tires. The quick engagement of most aftermarket clutches or the “grab” is greatly reduced and in most cases completely eliminated to allow for smooth clutch release and easy initial acceleration.
Developed with APR Motorsport to support their efforts in Grand-Am road racing, the Endurance configuration focuses on reduced transmission wear and perfect transitions from gear to gear. Kevlar and other more exotic materials are used to hold the power for many hours of abuse and torsion springs are used to damper between the engine and gearbox. Pedal feel is typically only slightly more rigid and initial engagement is certainly manageable resulting in a driveline component that quite handily eliminates any concerns from the Drivers and Crew Chief.
In no other form of racing are tenths and hundredths of a second more important nor is a vehicles driveline more abused in such a short period of time. It is with this understanding that DXD Racing has developed a line of clutches specific to the needs of this ever demanding sport. Pedal travel is reduced allowing for quicker launches off the tree and initial engagement is as rapid as possible getting all of the power to the ground instantaneously. Use of puck style discs and SFI approved Race Covers provide plenty of power handling capability and aids in the perfect pass every time.
