Description
Look no further than the Wiseco 18mm x 2.244in NonChromed TW Piston Pin for a wrist pin machined to an 18mm outer diameter and 2.244in length.
A piston’s wrist pin sits directly in the load path between the piston crown and the connecting rod, so its dimensions and surface finish have a direct effect on how smoothly the assembly runs. Rebuilders install a new pin with every new piston because the pin bore and pin must match precisely, and a worn or mismatched pin can lead to premature piston pin bore wear.
- 18.00mm outer diameter, 12.00mm inner diameter, 57.00mm length
- Superfinished outer diameter for a smooth running surface in the pin bore
- TW (tapered wall) NonChromed pin construction
- Engineered by Wiseco for strength and lightweight performance in the piston assembly
- Reduces friction between the pin and the piston pin bore during operation
- Connects the piston to the connecting rod’s small end for combustion load transfer
- Built for the reliability needed in high-speed, high-stress engine use
Sized at 18mm x 2.244in with a superfinished, NonChromed TW build, this Wiseco pin fits pistons machined for that exact bore and suits riders rebuilding a top end around this pin size.
