Single Piston Ring Set 4.160 Bore 1.0 1.0 2.0mm

The Single Piston Ring Set 4.160 Bore 1.0 1.0 2.0mm by MAHLE PISTONS is a precision engine component engineered for builders and mechanics who demand OEM-quality ring sets for custom or performance engine builds. This three-piece ring set is essential for any serious engine rebuild, stroker project, or high-revving application where bore diameter reaches 4.160 inches. MAHLE's reputation for metallurgical excellence means these rings deliver consistent compression seal, oil control, and durability across a wide range of engine configurations and fuel types.

Each ring in this set is precision-manufactured from premium cast iron or steel alloy to withstand extreme combustion pressures and thermal cycling. The 1.0mm compression ring, 1.0mm secondary compression ring, and 2.0mm oil control ring work together to maximize blow-by control while maintaining optimal oil film on cylinder walls. The 4.160-inch bore specification ensures a perfect fit in your custom piston package, eliminating end-gap guesswork and the risk of ring flutter or inadequate sealing. MAHLE's manufacturing tolerances are held to exacting standards, ensuring consistent ring tension and radial thickness across the entire set—critical for turbo, supercharged, or naturally aspirated builds pushing peak cylinder pressures.

This ring set is ideal for engine builders, performance shops, and DIY enthusiasts installing forged or hypereutectic pistons in 4.160-bore applications. Whether you're building a LS stroker, big-block Chevy, Ford Windsor, or any other platform that uses this bore size, proper ring selection is non-negotiable for engine longevity and performance. Always verify your piston manufacturer's ring groove specifications and install these rings with a ring compressor and proper end-gap checking procedures. Pairing this MAHLE ring set with quality pistons, a fresh hone, and fresh oil ensures your rebuild will deliver reliable power and consistent compression for years of hard use.
