KIBBLEWHITE Wrist Pin Bushing 20-0645

A wrist pin bushing is the critical bearing surface that allows your connecting rod to articulate smoothly around the piston pin during combustion cycles. Inadequate bushing material leads to excessive wear, increased friction, and potential catastrophic engine failure. The KIBBLEWHITE 20-0645 wrist pin bushing is engineered from SAE660 bearing bronze—a time-proven alloy that delivers superior load-carrying capacity and wear resistance in high-RPM applications.

Whether you're rebuilding a stock engine or assembling a race-spec short block, this bushing ensures precise clearance tolerances and long-term reliability under sustained performance demands. KIBBLEWHITE's domestic manufacturing guarantees consistent quality and tight dimensional control.
