Description
The wrist pin bushing is a critical wear component that directly impacts your Big Twin’s reliability and longevity. Over time, stock bushings develop excessive clearance, leading to piston slap, increased friction, and accelerated engine wear. This JIMS bushing maintains concentricity within .0002″—eliminating play and ensuring smooth piston travel through the entire power band.
Whether you’re rebuilding after high-mileage use or upgrading a performance build, a precision bronze bushing is non-negotiable for engines that demand consistent performance. The lead-in edge design streamlines installation, and U.S.A. manufacturing guarantees the quality control serious riders expect.
