Pin Bushing - SB Thin Wall (1)

The Pin Bushing - SB Thin Wall is a precision connecting rod component engineered for small-block engines requiring lightweight, high-rpm capable architecture. This small-diameter bushing serves as the critical pivot point between your connecting rod and piston pin, managing enormous loads and constant oscillation at engine speeds that demand absolute reliability. Whether you're building a street performance engine, bracket racing platform, or restoration project, this thin-wall design reduces reciprocating mass while maintaining structural integrity where it matters most.

Thin-wall bushings like this one are specifically engineered to reduce overall component weight without sacrificing load-carrying capacity, a critical advantage in high-rpm applications where inertial forces compound exponentially. The reduced wall thickness allows for tighter tolerances and improved oil clearance flow around the piston pin, enhancing lubrication efficiency and reducing friction losses. This design is particularly effective in small-block applications where every gram of rotating mass directly impacts power delivery, throttle response, and bearing longevity. The compact dimensions (1.6 x 1.1 x 2.95 inches) ensure compatibility with standard small-block rod geometry while the minimal weight of 0.03 pounds keeps your rotating assembly balanced and efficient.

Mechanics and engine builders restoring Chevrolet, Ford, Chrysler, and other domestic small-block platforms will find this bushing essential for any build prioritizing reliability and efficiency. Installation requires proper sizing to your specific piston pin diameter and connecting rod bore—precision matters here, as improper fit compromises both performance and engine longevity. This component pairs seamlessly with performance connecting rods and modern piston assemblies, making it ideal for rebuilds targeting 6000+ rpm operation. Verify your rod's pin bore specifications and piston pin diameter before ordering to ensure correct fitment for your particular application.
