Spec Clutch SF732 Stage 2 Clutch Kit - Kevlar Full Face Sprung Hub

The Spec Clutch SF732 Stage 2 Clutch Kit is a high-performance clutch system engineered for drivers who demand more than a stock clutch can deliver—without sacrificing everyday drivability. Ideal for mild to moderately modified naturally aspirated engines and power-adder builds, the Stage 2 is also an excellent long-life upgrade for stock power levels and spirited street driving.

At the heart of this kit is a segmented or full-faced pure Kevlar® friction disc with steel backing, delivering the smooth, stock-like engagement feel of the Stage 1 while stepping up torque capacity and wear life. The double-sprung hub features spring cover reliefs for added flexibility, and all load-bearing components are heat-treated for lasting strength and durability.

SPEC clutches are designed, hand-built, and tested in the U.S.A., with SFI-approved kits available across the product line. The Stage 2 sits within SPEC's street/strip range (Stages 1–3+), making it a smart step up for performance builds that still require reliable daily drivability.
