The MAHLE Original Piston Ring Set 4.000 Moly 5/64 5/64 3/16 is a precision-engineered component designed for serious engine builders and performance enthusiasts who demand OEM-quality reliability in their rebuilds. This piston ring set is ideal for restoring classic engines, rebuilding after failures, or assembling high-performance strokers.
Engineered to maintain proper compression and minimize blowby, this ring set features a 4.000-inch bore diameter with a molybdenum (moly) top ring. This combination enhances wear resistance and reduces friction during startup and high-load operation, ensuring durability and sealing integrity under demanding conditions.
Mechanics and engine builders trust MAHLE Original rings for stock restorations and performance upgrades. The precise ring gap specifications—5/64 inch on both the top and second rings, and 3/16 inch on the oil control ring—allow for proper thermal expansion while maintaining a reliable seal.
