The ACT 884006P Monoloc Collar is a one-piece direct replacement and performance upgrade for the standard two-piece wedge collar and wire ring used in pull-type clutch systems. Designed to improve release mechanism reliability, this collar helps maintain consistent bearing and pressure plate alignment during operation, including hard and fast shifts or vehicles equipped with performance modifications.

Manufactured from hardened chrome-moly steel, the ACT Monoloc Collar is engineered for long-term durability and dependable service. Its segmented retaining ring uses carefully calculated and tested spring tension to provide uniform loading across the bearing and pressure plate. This design reduces the potential for uneven loading caused by driver input or vehicle modifications and addresses common weaknesses associated with the original equipment design.
