About this part

Product Details

This is a Manley Performance wrist pin bushing, specifically designed for SBC I-beam connecting rods. If you're rebuilding the bottom end of your small-block Chevy engine, these bushings are a critical component for ensuring proper piston-to-rod clearance and smooth operation. They sit inside the small end of the connecting rod and allow the wrist pin to pivot freely without excessive wear on the rod itself.

Manley is known for making well-built internal engine components, and these bushings are no exception. They are made to precise tolerances to ensure a snug fit within the rod and a perfect mating surface for the wrist pin. Proper installation is key here; you'll want to ensure the rod is clean and that the bushing is pressed in correctly to maintain the intended clearance. This part is essential for any performance-oriented or high-mileage engine rebuild where reliability is paramount.
