Construction & Design

The IRONMAN clutch kit features a meticulously engineered design focused on durability and performance. The clutch disc is made from high-quality sintered iron, known for its excellent heat dissipation and wear resistance. The sprung hub design helps absorb torsional vibrations, reducing stress on drivetrain components and providing smoother engagement. The clutch assembly is paired with a heavy-duty pressure plate that maintains consistent clamping force, even under extreme conditions.

Action Clutch employs precise manufacturing processes, including TIG welding and CNC machining, to ensure perfect fitment and longevity. The kit's components are built to withstand high temperatures and intense use, making it a reliable upgrade for serious drivers. The heavy-duty construction also helps prevent clutch fade during prolonged track sessions or aggressive driving, ensuring your vehicle maintains optimal performance.

It is designed to fit directly onto the factory flywheel and transmission without the need for modifications. However, due to its high-performance nature, professional installation is recommended to ensure proper setup and alignment. No cutting, drilling, or tuning is typically required, but it is advisable to inspect and replace related components such as the release bearing and pilot bushing for optimal performance.
