CR Piston Ring Set 3.805 Bore 1.5 1.5 3.0mm

The CR Piston Ring Set 3.805 Bore 1.5 1.5 3.0mm from TOTAL SEAL is engineered for builders and mechanics who demand precision in high-performance engine builds. This complete ring set is designed for small-block and mid-size displacement engines requiring exact bore specifications, making it an essential component for street engines, race applications, and full engine rebuilds. Whether you're restoring a classic or optimizing modern horsepower, TOTAL SEAL piston rings provide the seal quality and longevity that separates a properly built engine from one that leaks compression and burns oil.

This ring set features a three-ring configuration with 1.5mm top ring, 1.5mm second ring, and 3.0mm oil ring dimensions, optimized to maintain proper compression sealing while minimizing blow-by and friction losses. The 3.805-inch bore specification ensures a precise fit in engines with that exact cylinder diameter—critical because even 0.005 inches of clearance variation degrades seal integrity and increases oil consumption. TOTAL SEAL's manufacturing process includes premium materials and controlled tolerances that prevent stiction and ensure smooth, reliable operation across wide temperature and RPM ranges, from idle to sustained high-boost applications.

This ring set is ideal for engine builders, professional mechanics, and enthusiasts rebuilding small-block engines—particularly those in the 305 to 350+ cubic-inch range common in Chevrolet, Ford, and Mopar platforms. Installation requires proper ring gap file-fitting and careful honing to specification; confirm your engine's exact bore diameter before ordering to guarantee fitment. The compact package weighs 0.74 lbs and ships ready for installation, making it a direct replacement or upgrade component for both original and performance builds seeking OEM-grade reliability with premium sealing characteristics.
