ACT HD 6-Pad Sprung Clutch Kit Subaru STI/Legacy - SB10-HDG6

240mm | 668 ft-lb | 2004-2021 STI | 2007-2009 Legacy GT spec.B

The ACT SB10-HDG6 Heavy Duty 6-Pad Race Sprung clutch kit delivers a 668 ft-lb engine torque rating for the listed Subaru STI and Legacy GT spec.B applications. Its ceramic six-pad disc is built for demanding heat and friction conditions, while the spring-centered hub cushions torsional vibration through the driveline. The Heavy Duty pressure plate uses a heat-treated diaphragm and rigid cover construction to maintain clamping force. An ACT Monoloc collar, release bearing, pilot bearing, alignment tool, and grease are included. This race-disc combination engages more abruptly than an organic street kit, making its holding and heat capability a key part of the purchase decision.
