Wiseco 101.956mm (4.014inch) Top Ring Ring Shelf Stock

This is a Wiseco 101.956mm (4.014 inch) top ring, designed to work with Wiseco 4-stroke pistons. Piston rings are critical for engine performance, handling everything from compression and sealing to oil control. When you're building an engine, especially for demanding applications, the rings you choose can make a big difference in how well the piston performs.

Wiseco develops these rings specifically to their own high standards, aiming for the best possible sealing and performance when paired with their pistons. They're tested to ensure they can handle race-ready conditions, meaning they're built to be robust and reliable under stress. This particular ring is a top ring, which is the first line of defense for sealing combustion pressure.
