Piston Ring Set 4.145 Clsic Gold 1.5 1.5 3.0mm

The Piston Ring Set 4.145 Classic Gold 1.5 1.5 3.0mm by TOTAL SEAL is engineered for engine builders and performance mechanics who demand precision in top-end compression and oil control. This ring set is designed for 4.145-inch bore diameters and represents the gold standard in aftermarket piston ring technology. Whether you're building a classic street engine, preparing a competition powerplant, or restoring a vintage automotive project, TOTAL SEAL's proven design maintains peak performance across a wide range of RPM and load conditions.

TOTAL SEAL's Classic Gold ring set features a precise 1.5mm top compression ring, 1.5mm second compression ring, and 3.0mm oil control ring configuration that balances blow-by reduction with minimal friction loss. This three-piece design optimizes ring gap clearance and radial tension to ensure consistent sealing across temperature cycling and varying combustion pressures. The metallic composition and heat-treatment process allow these rings to withstand elevated engine temperatures while maintaining dimensional stability—critical factors when operating at higher boost levels or extended RPM ranges.

Mechanics and engine builders working on small-block variants and specialty builds benefit from this ring set's precise bore-specific fitment and proven track record in boosting engine performance. The set is ideal for those looking to enhance their engine's efficiency and longevity, making it a valuable addition to any performance engine project.
