Patented 4 Terrain Off Road Cover Assembly: 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. Also featuring the ER2 grooved cover which increase torque capacity while also increase heat dissipation.
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.
4 Terrain Dual Friction Clutch Plate:
4Terrain Ultimate Clutch Kits feature a dual friction clutch plate. Organic material on the flywheel side is replaced with Aramid, the same material used in bulletproof vests, for improved fade resistance and increased torque capacity due to a higher coefficient of friction. 4Terrain Ultimate plates are the ultimate for your 4×4.
