Torque Capacity: 436 ft/lbs Increase Clamping Force: 38% Totally tough! ACT Heavy Duty Pressure Plates provide increased torque capacity, durability, and extended clutch life. What makes ACT Pressure Plates the highest standard in the industry? First, ACT manufacturing always begins with new units. ACT Pressure Plates are not rebuilt from worn out parts. Second, pressure is increased the right way. Altering the geometry alone is not enough. Instead, ACT engineers a stronger diaphragm. ACT diaphragms are heat-treated using an exclusive 3-stage process and the release bearing contact area is hardened to reduce wear. Third, ACT designs the pressure and release travel of the unit to be in the optimum working range. Finally, ACT assures consistency and precision by using proven assembly procedures. Every unit ACT produces is accurately balanced and tested. No guesswork, no hype, only proven engineering and calculated results for every ACT Heavy Duty. 4-pad solid center clutch design allows for quick engagement and increased durability! - Shifting is Quick & Sure Due to Rigid Design - Solid Hub Design Highly Durable Resistant to Heat - Copper Ceramic Material Holds Approximately 28% More Torque - 4-Pad Xtreme Race Discs Engage Harsher & Shift Faster - 90 Day Warranty Tech Notes: Not recommended for street use due to harsh engagement Availability: Usually ships in 5-7 business days.
