Connecting Rod Pin Bushings

The Connecting Rod Pin Bushings from MANLEY are precision-engineered components designed for serious engine builders and performance enthusiasts who demand reliability under extreme conditions. These bushings serve as the critical interface between the connecting rod and wrist pin, managing the oscillating loads and friction that occur thousands of times per minute during engine operation.

Manufactured to exacting tolerances, these bushings are made from high-quality materials that resist wear and maintain proper clearance even under sustained high-load scenarios. They are designed to distribute pressure evenly across the pin bore, reducing stress concentration and preventing galling or micro-welding that can occur in underbored or poorly fitted applications.

These bushings are essential for any serious engine rebuild involving performance connecting rods, particularly in forced-induction applications where peak cylinder pressures and piston acceleration demand superior bearing support. Correct installation with proper honing and sizing ensures optimal oil film retention, which is crucial for thermal management and friction control in modern turbocharged and naturally aspirated builds alike.
