About this part

Product Details

The SPEC Stage 5 clutch kit for your 1972-1986 Porsche 911 Carrera is built to handle serious power. This kit is designed for vehicles with significant engine modifications, capable of managing up to 650 ft-lbs of torque. It features a sprung, multi-plate design, which helps absorb shock and vibration, making it more manageable for daily driving than a solid, single-plate setup. The kit includes a high-performance pressure plate, two high-performance friction discs, and a billet steel flywheel, all engineered to work together for optimal engagement and durability.

This Stage 5 kit utilizes a unique sprung, multi-plate configuration. This advanced design is crucial for dissipating heat effectively under high-load conditions, which is common in modified 2.4L, 2.7L, 3.0L, and 3.2L engines. The billet steel flywheel is a solid choice, offering excellent thermal stability and a strong foundation for the clutch assembly. While this is a high-performance component, SPEC has focused on making the engagement as smooth as possible for a multi-plate system, balancing extreme holding power with drivability.

When installing this clutch kit, it's important to follow the manufacturer's recommended break-in procedure to ensure proper mating of the friction surfaces. This kit is a significant upgrade for any 911 owner looking to push their engine's performance further. It’s designed as a direct replacement for the factory clutch assembly, simplifying the installation process for experienced mechanics.
