Description
A worn or damaged mainshaft bearing race compromises transmission smoothness and accelerates wear on adjacent components, leading to costly rebuilds. The JIMS 35125-37 delivers OEM-grade precision fit and durability, restoring the tight tolerances your FLH transmission demands for reliable power delivery across the rpm band. This is a direct replacement—not an upgrade—but an essential maintenance component for any serious builder or enthusiast keeping a vintage Harley running strong.
Installation is straightforward for those with basic transmission experience, though professional builders often stock this race as part of a complete bearing set during a rebuild. The precision engineering ensures minimal runout and reduces parasitic friction losses in the drivetrain.
