Description
The Wiseco 12.44mm x 1.882in NonChromed SW Piston Pin is sized for engine builds that spec this exact wrist pin diameter and length.
Every piston relies on its wrist pin to transfer combustion force into the connecting rod, so the pin has to be dimensionally correct and free of wear for the assembly to run true. When a piston is replaced during a rebuild, the pin is replaced along with it, since an old pin can carry hidden wear from thousands of heat cycles that a new piston shouldn’t inherit.
- 12.44mm outer diameter by 1.882in overall length, an SW (single wall) pin profile
- NonChromed pin finish
- Engineered by Wiseco for strength and lightweight performance in the piston assembly
- Designed to reduce friction as the pin rotates in the piston pin bore
- Links the piston to the connecting rod’s small end for reliable power transfer
- Built for the reliability and endurance required in high-speed, high-stress applications
- Works with Wiseco piston pin locks to keep the pin retained in the piston
Matching the 12.44mm x 1.882in NonChromed SW specification, this Wiseco pin fits pistons machined to that exact size and is intended for riders replacing a piston or completing a top-end rebuild.
