The Action Clutch Ironman Sprung clutch kit for BMW 528i (1997–1998) 2.8L (M52) includes a lightened flywheel and offers a sprung-disc option for high-torque applications. It uses American sintered iron friction, a dual clamp-load pressure plate and enclosed spring retainers to prevent spring loss. Engagement is aggressive and may introduce light noise; this kit is intended for race-focused use rather than daily driving and increases holding capacity substantially over stock.
