Wrist Pin Bushing - SBC

The Wrist Pin Bushing – SBC from EAGLE is a precision-engineered component designed for small-block Chevrolet engine builds and rebuilds. This bronze bushing serves as a critical wear interface between the wrist pin and the connecting rod, reducing friction and preventing metal-to-metal contact that would otherwise lead to rapid component failure. Engine builders, performance shops, and restoration specialists rely on quality wrist pin bushings to ensure reliable power transfer and longevity in both street and competition applications.

This bushing features a 0.860-inch inner diameter and 0.973-inch outer diameter, with a 1.060-inch length that matches OEM and aftermarket small-block specifications. The bronze material composition provides superior load-carrying capacity and self-lubricating properties, allowing it to withstand high-rpm operation and sudden combustion pressures without galling or seizing. The natural (uncoated) bronze finish ensures compatibility with standard honing procedures during rod reconditioning, allowing machinists to achieve precise clearance fits essential for reliable operation.

Engine rebuilders and performance enthusiasts benefit from this EAGLE component when reconditioning connecting rods for small-block Chevy platforms, including 350, 327, and 305 variants. Proper installation requires careful honing to achieve the manufacturer's recommended clearance (typically 0.0015–0.003 inches over pin diameter) to balance durability with assembly integrity. This individual bushing is sold as a single unit, so builders should order quantity equal to the number of cylinders being rebuilt to ensure uniform wear characteristics across all connecting rods.
