Wiseco 21 × 50.8 × 9.57 mm Steel Piston Pin – SW9310 Alloy

Description

We have a few choices when it comes to choosing a piston pin. 5115 Material pins are chromium alloy and steel case hardened to 58-64 Rockwell C designed for normal wear and tear. 52100 Material Pins are high carbon chromium-bearing steel made of aircraft quality alloy and case hardened to 54-56 Rockwell C for high load capacity. 9310 Material Pins are high quality low carbon and are case hardened to 59-63 Rockwell C for turbo or nitrous applications.
