Piston Ring Set 4.045 1/16 1/16 3/16

The Piston Ring Set 4.045 1/16 1/16 3/16 from MAHLE PISTONS is an essential internal engine component for serious automotive enthusiasts engaged in rebuilding or performance-tuning their engines. This piston ring set is specifically designed for a 4.045-inch bore diameter, making it critical for precision-fit top-end work in various engine applications.

The set features a 1/16-inch top ring, a 1/16-inch second ring, and a 3/16-inch oil ring configuration, which is a proven design that effectively balances gas sealing efficiency with oil control. The top and second rings work to manage combustion chamber seal, minimizing blowby that can rob power and foul the crankcase, while the wider oil ring scrapes excess lubricant from cylinder walls and returns it to the oil pan. Manufactured to exacting tolerances, these rings are made from high-grade materials that can withstand the extreme temperatures and pressures generated during combustion.

This piston ring set is ideal for builders and mechanics working with 4.045-bore engines found in many big-block and stroker applications across domestic and performance platforms. Proper installation requires precision honing of cylinder walls and accurate ring gap adjustments to ensure optimal performance and longevity. MAHLE's reputation in both OEM and racing applications guarantees a consistent ring-to-bore fit, making this set a reliable choice for any engine rebuild or performance enhancement project.
