Piston Ring Set 4.315 Classic 1/16 1/16 3/16

The Piston Ring Set 4.315 Classic 1/16 1/16 3/16 from TOTAL SEAL is a precision-engineered ring kit designed for high-performance 8-cylinder racing engines. This file-fit piston ring set serves serious engine builders and performance enthusiasts who demand exact bore-to-ring clearance and superior sealing efficiency. Built for applications where standard production rings fall short, this classic race specification delivers the compression and blowby control required in competitive and street performance builds.

Each ring in this 4.315-inch bore set features a 1/16-inch top ring thickness, 1/16-inch second ring thickness, and 3/16-inch oil ring thickness—proportions optimized for race engine dynamics. Manufactured from ductile iron with plasma moly coating, the rings provide superior wear resistance and reduced friction compared to conventional cast iron designs. The plasma moly surface treatment minimizes scuffing during break-in and extends ring life under sustained high RPM operation, while standard tension ensures reliable sealing across the full operating range without excessive cylinder wall loading. File-fit construction requires individual fitting to your specific piston and bore combination, guaranteeing perfect clearance and maximum compression retention.

This ring set is ideal for engine builders restoring or upgrading classic V8 performance engines, including muscle cars and vintage race platforms. Installation requires proper measurement, filing, and gapping before installation—a task best handled by experienced builders familiar with piston ring dynamics. Verify your piston design, bore diameter, and desired compression ratio before ordering to ensure correct fit and optimal performance in your specific application.
