Wiseco 86.25mm x 1.0x1.2x2.8mm Ring Set Ring Shelf Stock

This product is a set of Wiseco piston rings, specifically sized for an 86.25mm bore. You get the top compression ring (1.00mm), the second ring (1.20mm), and the oil control ring (2.80mm) needed for one piston. These rings are crucial for proper engine function, handling compression, sealing the combustion chamber, and controlling oil flow to prevent it from entering the cylinder.

Wiseco develops these rings to work seamlessly with their own pistons, aiming for optimal sealing and performance. In an engine, the rings are what make direct contact with the cylinder wall, so their condition and fit are key to how well the piston performs its job. These are designed and tested for race-ready performance, meaning they are built to handle demanding conditions.
