Wiseco 102.921mm (4.052inch) Scraper Ring Ring Shelf Stock

Wiseco 4-stroke piston ring sets are made specifically to Wiseco's specifications to provide ultimate performance and sealing with Wiseco's wide variety of 4-stroke pistons. From compression and sealing to oil control, rings can make or break piston performance, which is why Wiseco rings are developed and tested for race-ready performance.

Product Overview

Wiseco Pro Tru line of pistons utilize a plasma moly “pre-gapped” ring set for the budget minded consumer. Wiseco Sport compact kits include the high quality NPR XX rings, which are the best quality steel nitrided top rings and napier style 2nd rings. Our late model EFI lineup and several small block Chevy pistons are designed around the our 1.2mm Steel Nitride and napier GFX ring sets. Many of our big block sets utilize a .043 back cut top ring for extra material thickness around the intake valve.

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only.
