Wiseco 103.63mm (4.080in) Auto Ring Set for 1 Piston Ring Shelf Stock

Starting with a 4.080 inch bore size, this Wiseco piston ring set is built for engines that use a single ring per piston. This design is often found in performance applications where reduced friction is a key goal, and it's important to have rings that seal effectively without adding unnecessary drag. Wiseco is a well-known name in performance engine components, and this set is designed to meet the demands of a performance rebuild.

The specific design for a '1 Piston Ring Shelf Stock' means these rings are intended for pistons that have a groove accommodating just one compression ring. This is a critical detail for ensuring proper fitment and function within the piston and cylinder wall. When you're rebuilding an engine, especially one where you're aiming for improved performance or efficiency, the right piston rings are essential for maintaining compression and controlling oil consumption. This set from Wiseco aims to provide that reliable seal.

It's important to note that this ring set is not CARB approved and cannot be shipped to California. Always double-check your specific piston and cylinder bore dimensions to ensure this 4.080 inch set is the correct choice for your engine build.
