4Terrain Ultimate Performance 4x4 Clutch Kit & Flywheel with Patented ER2 Technology - 4TUSRF1091N-A

Designed and manufactured as a direct replacement for the Original Equipment clutch system, the 4Terrain Ultimate Clutch Kit delivers a significant increase in torque capacity and durability. Each component is application-engineered, rigorously tested, and validated to ensure it meets—or exceeds—the performance requirements of the original unit.With more than 70 years of experience designing and manufacturing clutch systems for both OEM and Aftermarket use, Clutch Industries (CI) is the trusted choice for high-performance, fit-for-purpose 4x4 clutch solutions.PATENTED 4TERRAIN OFF-ROAD COVER ASSEMBLY4x4 vehicles demand higher torque capacity while maintaining excellent pedal feel and fine modulation control. These performance requirements generate additional heat, which can shorten service life if not properly managed.The 4Terrain cover assembly delivers increased clamp load for greater holding power and incorporates CI’s patented ER2 grooved cover, which both boosts torque capacity and dramatically improves heat dissipation—essential for off-road performance and heavy-duty use.SPHEROIDAL GRAPHITE CASTINGSOur SG Iron (Spheroidal Graphite) castings—also known as Anti-Burst castings—are approximately 300% stronger than standard castings. This enhanced strength not only increases durability by up to three times but also improves heat dispersion under extreme operating conditions.4TERRAIN DUAL FRICTION CLUTCH DISC4Terrain Ultimate Kits feature a dual friction clutch disc engineered for superior performance. The flywheel-side organic lining is replaced with Aramid fibre—the same high-strength material used in bulletproof vests—providing exceptional fade resistance and a higher coefficient of friction for greater torque capacity.The result is the ultimate clutch plate for serious 4x4 applications.
