ACT HD/Performance Street Sprung Clutch Kit for 2004-2012 Mitsubishi Eclipse and Lancer (MR1-HDSS)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2004-2012 Mitsubishi Eclipse GS, SE, and Spyder GS, as well as Lancer Ralliart models. This complete ACT clutch kit (MR1-HDSS) is engineered for drivers seeking increased torque capacity without sacrificing street driveability.
The kit features ACT's Heavy Duty pressure plate, which utilizes an exclusive diaphragm design to increase clamp load and maximize clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process to ensure consistent performance. Precision-stamped cover stampings provide the rigidity needed for high-stress applications. The Performance Street disc is constructed with premium organic materials and a high copper content for superior heat transfer, while the steel-backed lining offers exceptional burst strength.
