Description
Finding the correct pistons and gaskets to rebuild an overbored engine can be challenging, but you're in luck! These WSM Platinum Series Overbore Top End Piston Rebuild Kits are high-quality and feature construction that meets or exceeds OEM specifications. Every kit is made of high-grade materials to ensure it can withstand whatever your ride puts you through. Platinum series pistons feature specially formulated non-abrasive skirt coatings and hardened tops for added horsepower and longevity. These kits contain overbored pistons, ring sets, wrist pins, racing needle bearings, head & base gaskets, intake & exhaust gaskets, and improved E-clips. This kit is for cylinders that have already been overbored. WILL NOT WORK WITH STOCK BORE CYLINDERS/SLEEVES.
Features
- Made to exact OEM specifications
- Platinum Series Pistons are made of high strength hardened aluminum designed to prevent skirt and ring groove breakage
- The piston walls are treated with a nonabrasive coating which reduces heat and friction for added horsepower and greatly extends piston life
