Mahle Rings Performance Plasma Moly Steel HV385 Top Ring 3.326in x 1.0MM .143in RW Moly Ring Set

If you're rebuilding the top end of your engine, getting the right piston rings is crucial for sealing and performance. These Mahle OE piston rings are designed to fit standard 3.326-inch bore pistons, with a 1.0mm top ring groove and a .143-inch ring thickness. They feature a plasma moly steel construction, which is a popular choice for performance builds because it offers good wear resistance.

Mahle has been in the engine parts game for a long time, and these rings are a solid option for many engine builds. The plasma moly coating helps them seat well against the cylinder wall, which is important for maintaining compression and preventing oil from getting into the combustion chamber. Make sure to check your piston specifications to confirm they are designed for a 1.0mm top ring groove before ordering.
