Spec Clutch SC095 Stage 5 Performance Clutch Kit - Full-Metallic Sintered Iron Disc

The Spec Clutch SC095 Stage 5 Clutch Kit is engineered for the most demanding motorsport applications, delivering maximum torque capacity for heavily modified drag race, pulling, and autocross builds. This is a race-grade, full-metallic clutch system designed to handle extreme power levels where conventional clutch materials fall short.

Featuring a sintered iron, full-faced disc with an unsprung (rigid) hub, the Stage 5 offers the highest possible friction coefficient in the Spec single-disc lineup. The hub assembly uses 12 solid rivets and is heat-treated throughout for maximum strength and long-term durability under high-stress race conditions. A high-clamp pressure plate provides aggressive clamping force, with adjustability available on select applications. Torque capacity ranges from approximately 1,050 to 1,300 ft-lbs depending on configuration.

Important Notes: The Stage 5 clutch is intended for race use only. Engagement characteristics are abrupt and not suitable for comfortable street driving. Hydraulic clutch systems may require upgrades for proper clutch separation. Torque ratings are finalized at time of ordering and this kit is best configured with input from a Spec technical representative to ensure the correct setup for your specific application.
