Wrist Pin Bushing - SBM

The EAGLE Wrist Pin Bushing – SBM is a precision bronze bushing engineered for small-block engine rebuilds and high-performance modifications. As an experienced mechanic, you understand that wrist pin bushings are critical wear items that directly affect piston articulation, engine longevity, and overall reliability. This bronze bushing serves as the interface between the wrist pin and connecting rod, absorbing lateral loads and reducing friction during the intense reciprocating motion of your engine's rotating assembly. Whether you're restoring a classic build or refreshing a performance engine, selecting the correct wrist pin bushing specification is non-negotiable.

This bushing features a 0.930 inch inner diameter and 1.042 inch outer diameter with a length of 1.053 inches, delivering the tight clearance control necessary for consistent piston pin fit and proper load distribution. Bronze construction provides superior wear resistance and self-lubricating properties compared to aluminum or steel alternatives, allowing it to handle repeated thermal cycling and high-rpm operation without galling or seizure. The natural bronze finish offers excellent corrosion resistance in engine bay environments, and the compact 0.05 lb weight ensures it integrates seamlessly into standard small-block applications without affecting assembly balance or timing.

Technicians rebuilding small-block engines—particularly those working on vintage muscle cars, street performance builds, or vintage drag racing platforms—will find this EAGLE bushing essential for connecting rod preparation. Proper wrist pin bushing selection prevents premature wear, knock-on noise, and catastrophic rod failure under sustained load. Installation requires honing the connecting rod bushing bore to spec and press-fitting this component with precision tooling; consult your engine's rebuild manual for exact clearance requirements. Stock with this OEM-equivalent part for quick-turnaround service work or performance builds where reliability and proper fit are paramount.
