Piston Ring Set Classic Race 4.040 +5 Bore

The Piston Ring Set Classic Race 4.040 +5 Bore from TOTAL SEAL is engineered for use in racing applications, particularly those involving classic and vintage engines. This ring set is suitable for experienced engine builders and serious racers who seek to enhance engine performance and longevity. It addresses the challenge of maintaining proper ring seal across varying RPM ranges.

Designed for blocks bored 0.005 inches over the factory 4.040-inch specification, this ring set aims to minimize friction losses while ensuring effective blow-by control. The engineering focuses on consistent ring tension across temperature variations, which helps prevent gap growth that can lead to blow-by and power loss. This precision is crucial for high-performance engines, where even minor variations can significantly impact performance.

Classic race enthusiasts and hot rod builders will find this ring set beneficial for restoring or modifying engines to meet fresh tolerances. The set requires proper ring gap setting and bore verification during installation, ensuring optimal performance in racing conditions. This attention to detail is what distinguishes quality racing components from more economical alternatives.
