Piston Ring Set 4.560 Moly 1/16 1/16 3/16

The Piston Ring Set 4.560 Moly 1/16 1/16 3/16 from MAHLE ORIGINAL/CLEVITE is engineered for eight-cylinder engines requiring file-fit precision rings during complete engine rebuilds or high-performance upgrades. Whether you're restoring a classic muscle car, rebuilding a modified street engine, or servicing a performance vehicle, this OEM-quality ring set delivers the compression seal and blow-by control essential for reliable operation across a wide range of engine speeds and loads. File-fit rings demand careful honing and installation but reward the builder with superior ring seating and longevity.

Constructed from plasma moly–coated steel, these rings feature a 1/16-inch top ring thickness, 1/16-inch second ring thickness, and 3/16-inch oil ring thickness—a classic proportioning that balances compression retention with oil control and ring flutter resistance. The moly coating reduces friction and wear during ring break-in, while the standard tension specification maintains consistent bore contact without excessive drag. The 4.560-inch bore dimension indicates compatibility with large-displacement eight-cylinder engines commonly found in performance and vintage applications. File-fit construction requires precision honing to 4.560 inches plus the manufacturer's specified clearance, ensuring proper ring gap and side clearance for optimal performance.

Mechanics and engine builders selecting this piston ring set should verify exact bore specifications and hone cylinder walls to within the required tolerance band before installation. These rings suit applications ranging from naturally aspirated engines to moderate boost scenarios, provided cylinder pressures remain within the ring design envelope. Proper ring gap filing and installation with a ring compressor tool are mandatory; improper gap or installation can result in ring breakage or blow-by. This MAHLE ORIGINAL/CLEVITE kit represents OEM-grade engineering, making it a trusted choice for serious rebuilds where compression sealing and durability cannot be compromised.
