The ACT Monoloc Collar (884007P) is a one-piece, direct replacement or upgrade for the standard two-piece wedge collar and wire ring used in pull-type clutches. The spring tension of the segmented retaining ring is carefully calculated and tested for optimal performance, providing uniform loading on the release bearing and pressure plate to assure proper alignment regardless of driver influence or vehicle modifications. Monoloc's hardened chrome-moly steel construction is built for years of service.
