Piston Ring Set 4.160 1.5 1.5 3.0mm

The Piston Ring Set 4.160 1.5 1.5 3.0mm by MAHLE PISTONS is designed for serious engine builders and high-performance enthusiasts. This precision ring set is engineered for 4.160-inch bore diameters and is essential for both stock restorations and modified engines where ring seal integrity is crucial for performance.

Featuring a 1.5mm top compression ring, a 1.5mm second compression ring, and a 3.0mm oil control ring, this set is optimized for stable sealing across a wide RPM range while minimizing friction losses. The dual compression ring configuration evenly distributes pressure loads, reducing stress on individual rings and enhancing longevity under high-performance conditions.

Ideal for anyone machining a 4.160-inch bore block, this piston ring set is suitable for stroker engines, overbore builds, and precision restorations. Its premium material composition and precise tolerances ensure consistent bore contact pressure, preventing blow-by and maintaining engine efficiency.
