Description
When a piston calls for a 19mm x 2.303in wrist pin, the Wiseco 19mm x 2.303in NonChromed TW Piston Pin is machined to that exact diameter and length.
The wrist pin ties the piston to the connecting rod and has to hold up to the full force of combustion on every stroke, so its strength and fit inside the piston pin bore matter as much as the piston itself. Riders fit a fresh pin whenever a piston goes in, since the old pin has already absorbed the wear from its previous service life and shouldn’t be carried over into a new assembly.
- 19mm outer diameter by 2.303in overall length, a TW (tapered wall) pin profile
- NonChromed pin finish
- Engineered by Wiseco for strength and lightweight performance in the piston assembly
- Designed to minimize friction as the pin operates inside the piston pin bore
- Provides the connection between the piston and the connecting rod’s small end
- Built for the reliability and endurance demanded by high-speed, high-stress applications
- Retained in the piston with a matching Wiseco piston pin lock
Machined to 19mm x 2.303in in a NonChromed TW configuration, this Wiseco pin fits pistons built to that exact spec and is meant for riders working through a piston or top-end rebuild.
