4Terrain Off Road Clutch Kits: 4×4 systems need a higher torque capacity while retaining good pedal feel with fine modulation control. These characteristics inevitably increase heat which reduces service life. So the ideal 4×4 clutch system must also have improved heat dissipation. 4Terrain cover assemblies are in themselves high clamp load covers providing increased clamping force as compared to standard product. There are however two additional features. Spheroidal Graphite Castings Approximately 300% stronger than a standard casting this material (sometimes referred to as an Anti Burst casting) not only increases strength by up to 3 times, it also improves heat dispersion. Balanced Covers To insure that the clutch system performs at maximum efficiency and that no unwanted vibration is generated as the cover spins, all 4Terrain cover assemblies undergo a 2 stage balancing process. 4Terrain Off Road Clutch Plates The key to the success of the 4Terrain clutch plate lies in the unique design of the clutch plate. The flywheel side of the clutch plate incorporates a series of pressed organic segments specifically formulated in an Aramide compound.
