Piston Ring Set 4.535 Moly 1/16 1/16 3/16

The JE PISTONS Piston Ring Set 4.535 Moly 1/16 1/16 3/16 (J100F8-4530-5) is a premium race-series piston ring kit engineered for high-performance eight-cylinder engines requiring precision bore fit and maximum reliability. This file-fit ring set features plasma molybdenum coated ductile iron construction, delivering the thermal stability and wear resistance demanded by serious engine builders and motorsports competitors.

Built to JE PISTONS' exacting standards, this 4.535-inch bore piston ring set combines three critical design elements: 1/16-inch top ring thickness, 1/16-inch second ring thickness, and 3/16-inch oil ring thickness. The plasma moly coating reduces friction, minimizes blow-by, and extends ring life under sustained high-RPM operation—essential characteristics for competition engines, stroker builds, and naturally aspirated performance platforms. Standard tension rings deliver consistent compression sealing without excessive drag on cylinder walls, optimizing both power output and fuel efficiency in race and street applications.

This ring set serves engine builders, machine shops, and enthusiasts rebuilding eight-cylinder engines where bore diameter reaches 4.535 inches—common in LS-series variants, big-block Chevrolet builds, and other performance platforms. File-fit rings require hand-fitting to the specific piston and cylinder bore, ensuring optimal gap clearance and maximum sealing integrity. Buyers should verify bore diameter and ring gap specifications before installation and consult piston and cylinder bore documentation to confirm compatibility with their specific engine combination.

JE PISTONS is recognized throughout motorsports for manufacturing precision forged pistons and ring sets that meet OEM and competition standards. This eight-cylinder kit represents the brand's commitment to durability and performance consistency, backed by decades of race-track validation across drag racing, circle track, and street performance applications.
