Many Sonnax clutch hubs are designed for the extra-duty requirements of drag racing with Powerglide and other GM transmissions, for instance. Machined from a high-quality medium carbon steel forging, most hubs will accept five friction discs for the added load capacity needed in high horsepower race cars. All splines and thrust surfaces are precision-machined to exacting tolerances, and the unique lube hole pattern is designed to reduce drag on the friction discs in low gear. Sonnax clutch hubs are also available with or without lightening holes to reduce rotational weight.

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

XClutch Stage 1 clutch kits offer a variety of performance upgrades for both street and track applications. They are designed in-house and normally utilize a single plate organic, ceramic, or carbon friction disc along with an upgraded factory-style pressure plate. XClutch kits utilize a similar mechanism to the factory clutch, making them ideal enhancements for most vehicles with low to mid-level performance modifications. Stage 1 clutch kits are available in three distinct performance clutch packages—sprung, rigid solid, and steel-backed organic. Features and benefits of each: * 1A sprung organic—this range has been specifically designed for street vehicles that have minor engine and general performance modifications. These kits offer a sprung organic friction disc that allows for great drivability, while offering improved clamping force through the use of a performance pressure plate. * 1G rigid solid organic—with a rigid center version of the organic disc, this range is ideal for street vehicles and light track use. These kits are often available with a lightweight alloy pressure plate and performance flywheel. * 1T steel-backed organic--this range offers a higher burst strength by bonding the organic friction material directly to a steel backing plate. These kits are ideal for high performance vehicles used on the street with occasional track use.

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.
