Configuration Details
Configuration: ACT6240529 (ACT6240529)
Aggressive engagement, quick shifts, mild to moderate gear rattle; Premium ceramic friction materials provide moderate wear rates and high heat tolerance; Utilizes wraparound spring windows, thicker retainer stampings and a heat-treated, spring steel drive plate to provide support, reduce stress concentrations and increase strength and reliability; Recommended for high horsepower street or race use; High burst strength and holds 28% more torque than typical organic materials This Part Fits:
Configuration: ACT6240029 (ACT6240029)
6240029 is a 6-pad rigid race disc made with high quality ceramic friction materials. The disc engagement is harsher, but shifting is faster. The race disc features top grade rivets to securely fasten the part together. The rivet design and materials are carefully selected for maximum strength. The 6-pad rigid race disc is recommended for larger clutch sizes to absorb more heat and for smoother engagement. This Part Fits:
Configuration: ACT4240029 (ACT4240029)
4240029 is a 4-pad rigid race disc made with high quality, ceramic friction materials. The disc engagement is harsher, but shifting is faster. The race disc features top grade rivets to securely fasten the part together. The rivet design and materials are carefully selected for maximum strength. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines. This Part Fits:
Configuration: ACT3000815 (ACT3000815)
3000815 is a performance street disc and the most popular disc purchased. It features premium organic materials with high copper content for better heat transfer. Performance street discs allow for quicker shifting and smooth engagement. These discs feature a reduced marcel for faster shift action to complement ACT pressure plates. ACT spring-centered assemblies use bushings and cone springs similar to factory clutch discs. This creates frictional dampening, which improves clutch life and reduces noise. Quiet operation with increased strength and reliability. This Part Fits:
Configuration: ACT3000807 (ACT3000807)
3000807 is a street rigid disc featuring premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. These discs are modified with reduced marcel for faster shift action to complement ACT pressure plates. The chrome-moly hub is heat-treated for strength and durability. Rivet design and materials are carefully selected for maximum strength. Lightweight, solid-hub design allows for quicker shifting and engagement. ACT's street rigid-hub discs provide race-proven performance with street manageability. This Part Fits:
