JE Pistons Straight Wall Pin - 2.500 in L .791 in OD Sharp Edge 51 Series 5115 Low Carbon Steel

This JE Pistons 51 Series piston pin is made from low carbon steel and is case hardened for improved durability. It measures 2.500 inches long with a 0.791 inch outer diameter and a 0.140 inch wall thickness. The straight wall design and sharp edge are specific features for certain engine builds. These pins are designed to connect the piston to the connecting rod, handling the significant forces involved during combustion and power delivery.

The case hardening process on this pin adds a tough outer layer while maintaining a more ductile core, helping it withstand repeated stress and impact within the engine. Its precise dimensions ensure a proper fit within the piston and connecting rod, which is crucial for smooth engine operation and longevity. This is a single pin, sold individually, for applications where a specific pin size and material are required.
