Description
The Wiseco 20mm x 2.002in NonChromed TW Piston Pin covers builds that call for a 20mm diameter pin at 2.002in in length.
A piston stays aligned in the bore only as long as its wrist pin and retaining clips work together correctly, which is why the pin is treated as a wear item alongside the piston itself. Anytime the piston assembly is opened up for service, fitting a new pin keeps the whole package matched and functioning at its intended tolerance.
- 20mm outer diameter by 2.002in overall length, a TW (tapered wall) pin profile
- NonChromed pin finish
- Designed for flawless compatibility with Wiseco piston pin locks and retainer clips
- Keeps the piston assembly secure and aligned even under demanding conditions
- Engineered by Wiseco for strength as part of the overall piston assembly
- Connects the piston to the connecting rod’s small end for combustion load transfer
- Works with Wiseco’s retaining clip sets to keep the pin from migrating in the bore
Specified at 20mm x 2.002in in a NonChromed TW build, this Wiseco pin fits pistons machined to that size and is intended for riders rebuilding a top end with matched pin and clips.
