Action Clutch ACR-38858 Stage 3 1MS Single-Disc Performance Clutch Kit

The Action Clutch ACR-38858 Stage 3 (1MS) Single-Disc Clutch Kit is a high-performance clutch system engineered for demanding street and track applications. Built for heavy-duty street use and occasional drag, road course, or drift racing, this kit delivers a significant upgrade in torque holding capacity and engagement feel over a stock clutch.

At the core of the Stage 3 1MS system is a MIBA Sprung Ceramic disc, available in a 4 or 6-puck configuration. The sprung hub design provides moderate dampening for improved streetability compared to a solid disc setup. The encapsulated disc springs use a fully enclosed retainer system, protecting against spring failures that can cause serious transmission or engine damage.
