XClutch Stage 2 Clutch Kits

XClutch Stage 2 clutch kits offer performance upgrades for both street and track applications. Designed in-house, XClutch utilizes the latest ceramic technology in their Stage 2 kits offering either a cushioned or a sprung-style friction disc. They are mated with a high performance pressure plate and are recommended for vehicles requiring a higher level of torque holding and heat capacity. Features: * 1C cushioned ceramic—the discs offer a dampening layer between the two friction surfaces which is clamped together as the force of the pressure plate is exerted on the disc. This dampening along with a sprung hub offers drivability despite the ceramic friction surface. These kits are ideal for track cars that require some drivability or very high-horsepower street vehicles that require the added heat capacity of the ceramic friction material. * 1B sprung ceramic—these friction discs offer a sprung center to allow for drivability and are specifically designed for track use with minor street use. The kits offer great heat capacity due to the ceramic friction material and are available for a wide range of performance vehicles.

South Bend Clutch Stage 3 Daily Driver Clutch Kits

South Bend Clutch Stage 3 Daily Driver clutch kits are recommended for single mass flywheel (SMF), when original design is dual mass flywheel (DMF). These clutch packages are designed for high-horsepower vehicles desiring a start performance similar to OE. The pressure plate is race engineered (SS) and SFI-approved with significant load increase over stage 1 and 2 pressure plates (+600-800 lbs.). Expect a pedal effort increase of 20 to 25 percent. Discs are assembled with heat-treated wear-resistant hubs, as well as 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 OE start performance. A performance organic friction material with a high metal content increases torque and rpm capability—and maintains low operating temperatures, which reduce wear and glazing. South Bend Clutch Stage 3 Daily Driver clutch kits are the perfect match for your high performance street machine and occasional track use. Order the kit recommended for your application.

ACT Race Clutch Discs

ACT race clutch discs are available in three distinct styles--choose the options that best suit your application. Spring-centered discs are the most popular and feature reduced driveline shock and spline wear with quieter operation. Rigid-hub versions offer improved durability but increase gear noise and spline wear. For either of those hub designs, you can choose six pads for better heat management and engagement, or four pads for the quickest shifting. Sintered iron discs offer the highest torque capacity and ultra-high heat capacity. They're designed for cars using clutch-less shifting or drag racing transmissions. Additional product details: * Premium ceramic friction materials provide high-heat tolerance, high coefficient of friction, and low wear rates * Carefully broached splines provide exact fit onto the transmission input shaft for long spline life and better clutch release * Heavy-duty torsional dampening springs are provided in the best sizes and spring rates to help reduce noise * Drive plates are made of high-carbon steel; heat-treated and black zinc coated to resist bending, cracking, fatigue, and rusting * Certified to SFI specifications
