CP Super Finish Wristpin .927in Dia x 2.500in Length .230in Wall 5100 Chromoly Chamfered

The .230 inch wall thickness on this CP Super Finish wristpin is a notable detail, contributing to its overall strength. It’s made from 5100 Chromoly steel, a well-known material for its balance of toughness and durability, especially in high-stress engine applications. This specific pin measures .927 inches in diameter and is 2.500 inches long, designed to fit precisely within compatible pistons and connecting rods.

The 'Super Finish' in the name refers to the surface treatment, which helps reduce friction where the pin contacts the piston and connecting rod. This improved surface smoothness can lead to better oil retention and less wear over time, especially important in performance engines where these components see a lot of action. The chamfered ends are a practical touch, making installation a bit easier by preventing sharp edges from snagging during assembly.
