MAHLE 3010864 Moly Claimer Piston Ring Set 4.350in Bore 5/64in Top Ring

The MAHLE 3010864 is a plasma-moly piston ring set engineered for 4.350-inch bore oval track claimer series race engines. Designed to deliver many of the same proven benefits as MAHLE's premium performance ring sets at an economical price point, this set is purpose-built for the demands of high-RPM oval track competition.

The set features a 5/64-inch positively twisted top ring with a plasma-moly face coating, providing outstanding sealing under race conditions. The moly inlay reduces friction, promotes rapid break-in, and extends ring and bore life compared to uncoated alternatives. MAHLE's ultra-flat ring flanks maximize ring-to-piston groove sealing for consistent compression retention.
