DXD Racing clutches are a product line developed by SouthBend Clutch and have been tested on the street and the track with many different friction materials, pressure plate loads and flywheel designs. They have created a clutch lineup with perfect balance and symmetry without compromise in reliability or drivability.

Each clutch system is specially matched to specific driving styles, uses and power levels to ensure the needs of each driver are accomplished. In the past, a compromise between drivability and pedal feel had to be made to achieve power handling. Drag racing will have different requirements for clutch operation than daily spirited driving or endurance racing. One clutch certainly does not fit all and SouthBend has done the homework for you to recommend a clutch system that meets your specific goals.

Each DXD Racing clutch is offered in a Daily, Endurance or Drag configuration to ideally match the uses of the driver. See pictures in the "Image Gallery."

Please select which clutch stage you wish to purchase in the options section at the top of the page.

STAGE 2 CLUTCHES

Offered in specific configurations of Daily or Endurance, 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.

STAGE 2 DAILY - Includes DXD Flywheel & Crank bolts

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 coefficient 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.

STAGE 2 ENDURANCE - Includes DXD Flywheel & Crank bolts

This clutch system is designed for the racing climate. The pressure plate is precision balanced for vibration free operation at high RPM. The pressure plate fulcrum is altered for a positive disengagement and a quick shift. The disc is engineered with a Dual Damped design to provide accurate control when accelerating through corners. The friction material is a hybrid using a full face Feramic (Sintered Iron) lining on the flywheel side and a high metal content Organic lining on the pressure plate side. Engagement is positive yet buffered due to the high graphite content unique to feramic facings. Recommended uses are daily and street with an emphasis on Rally and Endurance racing. An SFI approved single mass flywheel is recommended for this application to get optimal performance.

STAGE 3 CLUTCHES

STAGE 3 DAILY - Includes DXD Flywheel & Crank bolts

This clutch package is designed for high HP vehicles desiring a start performance similar to O.E. The pressure plate is Race Engineered (SS) and SFI approved with significant load increase over stage 1 or 2 pressure plates (+600-800 lbs.). Expect a pedal effort increase of 20%-25%. Discs are assembled with heat-treated wear resistant hubs; drive plates and springs for high load transfer and dependable operation. The sprung centers on the disc, in conjunction with the marcel fin between the linings, create a dual dampening effect that simulates O.E. start performance. A Performance Organic friction material with a high metal content increases torque and RPM capability and maintains low operating temperatures reducing wear and glazing. Recommended usages are daily, spirited street and occasional track.

STAGE 3 ENDURANCE - Includes DXD Flywheel & Crank bolts

This kit uses the same Race Engineered SFI approved pressure plate as the Stage 3 Daily upgrade. The disc is designed for the special needs of a vehicle with circuit racing in mind. Kevlar friction material is used for its unique static to dynamic ratios of friction coefficients at high energy levels. This translates to a perfect transition from one gear to the next. Discs are assembled with only performance components and equipped with torsion springs functioning as a damper between engine and gearbox. Recommended usages are Rally, Endurance Race, Clubsport, Autocross, Street and Daily.

SINGLE MASS STEEL FLYWHEELS

SouthBend DXD Flywheels are made from low carbon, hot rolled steel that is highly resistant to warping and perfectly suited for the friction materials mated to them. Single mount CNC machining guarantees precise tolerances and perfect balance, exceeding O.E. specifications. Extensive field-testing has been done to determine the proper weight for each specific vehicle and to ensure smooth operation, safety and durability under extreme operating conditions. They are SFI approved.

PLEASE NOTE:
