Wiseco Top End Piston & Gasket Rebuild Kit

These kits contain everything you need to complete your rebuild the right way, the first time. High-quality parts specifically chosen to match the forged pistons are included in this kit for easy one-stop shopping.

Wiseco’s ArmorGlide coating eliminates the need to check for different piston sizing, and the only thing to confirm before fitment is bore size.
