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

The Piston Ring Set 4.060 1/16 1/16 3/16 is a premium ductile moly ring kit engineered for serious engine builders and mechanics tackling high-performance eight-cylinder builds. Whether you're rebuilding a stroker engine, restoring a classic muscle car, or upgrading a modern performance platform, this file-fit piston ring set delivers the precision and durability required for demanding applications. These rings are specifically designed for 4.060-inch bore engines where exact ring gap control and reliable sealing are non-negotiable.

Manufactured from ductile iron with a plasma moly face coating, this ring set combines low-tension design with superior wear resistance and oil control. The ring stack configuration—1/16-inch top and second rings paired with a 3/16-inch oil ring—optimizes compression sealing while minimizing friction and oil consumption across the RPM range. The plasma moly coating reduces scuffing during initial engine break-in and extends ring life under elevated temperatures and boost conditions. File-fit specification means you'll need to hand-fit each ring to your specific bore diameter, ensuring zero clearance gaps and maximum performance integrity.

This ring set is ideal for builders planning moderate to aggressive power levels who demand repeatability and control over their engine's internal dynamics. Install these rings with precision piston ring filing tools and a ring compressor rated for low-tension applications. The low-tension design reduces friction losses, making this set popular in fuel-efficient builds, naturally aspirated performance engines, and supercharged applications where ring blow-by control is critical. Always consult your engine's specific clearance requirements and piston specifications before final installation.
