The ACT BM17-HDSS clutch kit combines the popular Heavy Duty pressure plate with a Performance Street sprung disc, engineered for drivers seeking increased torque capacity without sacrificing street driveability. The Heavy Duty pressure plate utilizes an exclusive diaphragm design subjected to a four-stage heat-treating process, which significantly increases clamp load and reduces deflection for a more consistent pedal feel and longer service life.

The Performance Street disc is constructed with premium organic friction materials featuring high copper content for superior heat dissipation. Steel-backed linings provide increased burst strength, while the reduced marcel design allows for faster shift action. This sprung-center disc helps dampen drivetrain vibrations to maintain smooth engagement for daily driving and performance use.
