4.630 CS Piston Ring Set File Fit 1/16 1/16 3/16

The 4.630 CS Piston Ring Set File Fit 1/16 1/16 3/16 from Total Seal is engineered for serious engine builders and performance enthusiasts who demand precision ring control and blowby reduction. This file-fit ring set is designed for applications requiring a 4.630-inch bore diameter, making it ideal for stroker builds, racing engines, and high-compression domestic powerplants. Whether you're rebuilding a big-block Chevy, Ford, or Mopar engine, this ring set delivers the critical seal needed to maximize compression and minimize oil consumption during both street and competition use.

Total Seal's CS (Classic Series) construction combines advanced ring materials with precise gap specifications: 1/16-inch top ring gap, 1/16-inch second ring gap, and 3/16-inch oil ring gap. File-fit rings require custom honing to your specific bore, ensuring perfect ring-to-wall contact and minimal blowby that steals horsepower and increases crankcase pressure. The staggered gap design prevents ring flutter at high RPM while the engineered ring face maintains consistent oil film strength across the entire stroke. This level of precision engineering is what separates professional-grade rings from mass-produced alternatives.

Mechanics and engine builders trust Total Seal file-fit rings when assembling competition engines, restorations, or high-performance builds where every horsepower counts. Installation requires proper bore honing to the exact specifications matching your ring set gaps—this is not a drop-in ring set, but rather a precision component demanding professional machine shop preparation. The 1.2 lb ring set fits standard piston grooves and works across various four-cylinder and six-cylinder platforms with 4.630-inch bore diameters. Proper honing, gapped measurement, and careful ring installation ensure years of reliable compression and reduced oil consumption in any demanding application.
