Spec Clutch SH415-2 Stage 5 Full-Metallic Performance Clutch Kit

The Spec Clutch SH415-2 Stage 5 Clutch Kit is SPEC's highest-grip single-disc clutch solution, engineered for drivers who demand maximum torque transfer in extreme street and racing environments. Featuring a full-metallic sintered iron friction disc with the highest available friction coefficient in the SPEC lineup, this kit delivers instant, aggressive engagement with zero slip under load.

The Stage 5 is technically street-drivable but is best suited for purpose-built performance and race applications. The solid 12-rivet unsprung hub and disc assembly is heat-treated for exceptional strength and durability under the repeated stress of hard launches and high-horsepower use. A high-clamp pressure plate maximizes clamping force to match the aggressive friction material.
