The 4Terrain Heavy Duty Clutch Kit offers superior torque, durability, heat dissipation, and smooth operation, engineered for demanding off-road applications. Improved Heat Dissipation: Patented ER2 grooved cover and advanced materials reduce heat build-up, improving extending the clutch system’s service life. Durable and Reliable: High-strength spheroidal graphite castings and balanced cover assemblies provide exceptional durability and vibration-free operation for long-term reliability. The 4Terrain Heavy Duty replacement clutch kit is designed to exceed the performance and durability of the original equipment clutch system. With a focus on increased torque capacity, every component is rigorously tested and developed for specific vehicle applications. Backed by over 70 years of expertise in OEM and aftermarket clutch manufacturing, CI delivers unmatched quality and reliability in clutch systems. Patented 4Terrain Off-Road Cover Assembly: Ideal for demanding 4x4 applications, this system delivers superior torque capacity while maintaining smooth pedal feel and precise modulation control. Its high clamp load design provides increased clamping force, essential for off-road performance.

Spheroidal Graphite Castings: Constructed from advanced materials up to 300% stronger than standard castings, these components enhance strength and heat dispersion. Known as Anti-Burst castings, they ensure durability under extreme conditions, prolonging service life. Balanced Cover Assemblies: A two-stage balancing process ensures vibration-free operation and maximum efficiency, delivering consistent performance and durability in even the most demanding environments.

4Terrain Heavy Duty is a tough, no-nonsense clutch upgrade designed for hardworking vehicles. Engineered to handle high torque loads it leaves standard specification clutches behind.

The system has been engineered for the following uses that need higher than original torque capacity:

4Terrain Heavy Duty delivers an increase in torque capacity through the patented ER² heavy duty cover assembly. This system features an increased clamp load of on average 20% higher than OE. The system also gains torque capacity from the Spheroidal Graphite Iron (SG Iron) ER² grooved pressure plate. This groove has been specifically designed to increase the Mean Effective Radius of the pressure plate and assist in heat removal. The increase in the Mean Effective Radius of the cover assembly gives a significant increase in torque capacity.
