Piston Ring Set 4.060 Moly 1/16 1/16 3/16

The Piston Ring Set 4.060 Moly 1/16 1/16 3/16 is designed for high-performance engine builds and rebuild applications where durability and precision sealing are essential. This product is ideal for engine builders working on 4.060-inch bore blocks, commonly found in Big Block Chevy, Gen III LS, and other performance engines.

Engineered by MAHLE ORIGINAL/CLEVITE, this piston ring set features moly (molybdenum) coating on the compression rings, which helps reduce friction, improve ring-to-cylinder wall conformance, and extend ring life under high heat and load conditions. The 1/16 1/16 3/16 ring thickness configuration is specifically calibrated for 4.060-inch bore diameter applications, ensuring proper end-gap clearance and radial tension.

Moly-faced rings are particularly effective in fresh bores, breaking in faster and maintaining consistent blow-by control across extended RPM ranges. This makes the piston ring set suitable for turbocharged, supercharged, or naturally aspirated performance engines that require elevated boost or internal modifications.
