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

Input housing failure at the shaft and forward piston areas is common in high-torque 4L60, 4L60-E, 4L65-E, and 4L70-E transmissions. Also, the input drum assembly is known to crack and strip out splines where the input shaft is pressed into it (where the overrun piston rides). Sonnax input housing sleeve kits—forward sleeve kits and overrun sleeve kits—when used in combination with each other, greatly increase the maximum strength of the housing for additional torque capacity and can prevent these failures. Sonnax input housing overrun and forward sleeve kits are offered separately. Both sleeves feature high-strength, chromoly construction that increases housing torque capacity by protecting the shaft and either the forward piston or overrun piston areas. Each kit will include piston, reinforcement sleeve, and outer and inner piston seal.
