The 44lb Pro-Mass Flywheel boasts a 28% increase of inertia reducing the chance of stalling or rapid RPM loss, making drivability easier over tough obstacles and terrain. For versatility, ACT’s new Flywheel is a direct replacement to the OEM Flywheel and can be used with the OEM 11” Clutch but offers the benefit of 16% more clutch surface area when combined with the ACT Clutch. A second bolt pattern is also drilled for use with the earlier 10.5” JK Clutch if desired.
For the assurance of safety, each ACT Flywheel is certified to meet SFI Specification 1.1 standards, making them legal for competition where SFI 1.1 certification is required or recommended.
