Spec Clutch ST372 Stage 2 Kevlar Clutch Kit

The Spec Clutch ST372 Stage 2 Clutch Kit is an ideal performance upgrade for mildly to moderately modified naturally aspirated and forced-induction engines. It delivers stock-like daily drivability with a meaningful increase in torque capacity and service life over a stock or Stage 1 unit — making it equally at home on a daily driver or a spirited weekend machine.

At the heart of the Stage 2 kit is a pure Kevlar friction disc with a steel backing, a proven material combination that provides excellent engagement feel, superior wear resistance, and higher torque holding capacity compared to standard organic linings. The high-clamp pressure plate increases clamping force over stock for improved power transfer without sacrificing smooth, predictable engagement. The high-torque sprung hub and disc assembly features double-wound springs with spring cover reliefs for added flexibility, and heat-treated components throughout ensure long-term strength and durability.
