Patented 4Terrain Off Road Cover Assembly

4WD 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 4WD 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 Graphte 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.
