Piston Ring Set 4.470 Bore .017 1/16 3/16

The Piston Ring Set 4.470 Bore .017 1/16 3/16 by Total Seal represents the gold standard for serious engine builders and high-performance mechanics who demand precision compression control and reliability under extreme conditions. This ring set is engineered for engines requiring exact bore diameter matching and optimal ring gap tolerances, making it essential for custom builds, racing applications, and performance restorations where factory specifications no longer apply. Whether you're assembling a stroker motor, rebuilding a vintage V8, or fine-tuning a competition engine, this piston ring set delivers the sealing integrity and durability that separates amateur work from professional-grade results.

Total Seal's advanced ring technology features a three-piece design with a compression ring, wiper ring, and oil control ring that work in concert to minimize blow-by, reduce friction, and maximize combustion chamber sealing across the entire RPM band. The .017 top ring gap specification and 1/16 inch second ring dimensions, combined with the 3/16 inch oil ring, ensure precise clearance for the 4.470 bore diameter while maintaining adequate expansion characteristics during thermal cycling. This balanced geometry prevents ring flutter at high RPMs while delivering superior oil control and reduced carbon buildup—critical factors in engines that see sustained boost, nitrous oxide, or continuous wide-open-throttle operation. The compact 5 x 2 x 10 inch package contains all four ring sets per cylinder, ready for immediate installation without field modification.

Professional engine builders, transmission shops, and dedicated performance enthusiasts will recognize the Total Seal name as the solution when off-the-shelf rings won't cut it. This ring set is ideal for customers running 4.470 bore blocks—whether that's a big-block Chevy, Ford, or specialty racing application—where dimensional accuracy directly impacts power output and engine longevity. Installation requires proper ring end-gap verification during block preparation and careful piston-to-bore clearance confirmation; always consult your engine builder's specifications and verify bore diameter before ordering. Weighing just 1.1 lbs, this compact yet critical component belongs in every serious hot rodder's and professional mechanic's inventory.
