PC-1054-S1H, Stage 1 Street HD is a clutch kit for drivers who want increased torque capacity and durability, together with a direct feel when paired with a single-mass flywheel.
Why choose this clutch kit?

- Compatible with a single-mass flywheel – optimised for single-mass flywheel setups, providing quicker throttle response and a more direct feel through the drivetrain.
- High-resistance organic friction lining – uses organic friction material with a steel backing for good heat resistance, smooth engagement and a long service life.
- For repeated loads – developed for frequent dynamic driving, hard acceleration and elevated temperatures without compromising reliability.
