Wiseco Pistons W5414 Piston Pins & Locks

Piston Lock
Round Wire

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.

5115 Material Pin

• Standard grade chromium alloy steel
• Case hardened to 58-64 Rockwell C
• Ground to a surface finish of .15 Ra or better
• Designed to withstand the normal wear and tear of an aftermarket engine

52100 Material Pin

• High carbon, chromium-bearing steel
• Aircraft quality alloy
• Case hardened to 54-56 Rockwell C
• Through hardened
• Ground to a fine finish
• Designed for high load capacity
• Designed for outstanding wear and abrasion resistance

9310 Material Pin

• High quality, low carbon, case hardened steel
• Case hardened to 59-63 Rockwell C
• Ground to a superfinish (.025 Ra or better)
• Designed for use in applications which require high surface strength combined with high core toughness
• Excellent to use in applications where high contact stress is combined with high shock and impact loading, such as turbo / nitrous applications
