WARNING: This product can expose you to chemicals that are known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, visit www.P65warnings.ca.gov.Upgrading your clutch is essential when the stock unit slips under increased load, and the ACT BM2-HDSS Heavy Duty Performance Street Sprung Clutch Kit resolves this issue for modified street vehicles. This kit combines a Heavy Duty pressure plate with a performance street disc to increase torque capacity by 20 percent up to 270 ft/lbs. The sprung hub design reduces drivetrain shock while premium organic materials with high copper content deliver enhanced heat transfer and a smooth, positive engagement.
Please note: This kit has a specific part fitment requirement and must be used with an ACT flywheel (not included in this kit) to accommodate the sprung hub disc clearance. This kit is recommended for street and race use, delivering light to moderate pedal effort with long-lasting friction life.
