HD Clutch Kit Subaru/ Saab

The HD Clutch Kit Subaru/Saab (Model SB5-HDSS) by Advanced Clutch Technology is designed for drivers who require dependable power transfer in high-performance situations. This heavy-duty single-disc clutch assembly is ideal for modified Subaru EJ and turbo Saab engines, providing a robust solution for those experiencing slippage with stock clutches during aggressive driving.

This clutch kit addresses the limitations of OEM clutches by featuring a reinforced pressure plate with increased clamp load and organically-bonded friction surfaces that resist heat cycles, preventing glazing and fade. The single-disc design maintains compatibility with OEM flywheels, while the optimized damper spring rate minimizes chatter and reduces wear on input shaft bearings, making it suitable for higher torque outputs.

Ideal for performance enthusiasts, this clutch kit allows Subaru EJ-series and Saab owners to maintain stock driveline geometry without the need for custom fabrication. Installation requires basic mechanical skills and involves transmission removal, with most technicians completing the process in approximately 3–4 hours.
