Description
Proper crankcase oiling is fundamental to Knucklehead longevity, and a worn or inadequate bushing compromises oil delivery to critical bearing surfaces. The JIMS Right-Side Crankcase Bushing restores full 360° lubrication flow, reducing wear on your engine’s most stressed components and preventing the catastrophic bearing damage that comes from oil starvation. If you’re running a vintage FL and want reliable, consistent engine performance, this precision-engineered bushing is non-negotiable maintenance.
