Hastings Piston Ring Set for 107 Cubic Inch

Elevate your engine's performance with the high-quality Hastings 107 cubic inch piston ring set. Engineered for precision and durability, this complete replacement set provides superior sealing and oil control for optimal power transfer and longevity.

Description

Designed and manufactured by Hastings, a trusted name in engine components, this piston ring set is proudly made in the USA, ensuring exceptional quality and reliability. Each set is meticulously crafted to meet the demands of high-performance engines, featuring a 3.937" bore size and a +0.005" piston size. The top compression rings utilize a Barrel Face design, enhanced with a PVD (Physical Vapor Deposition) coating. This advanced coating significantly improves heat transfer between the piston and cylinder wall while effectively controlling combustion chamber gases, allowing for maximum energy transfer to the crankshaft. The second compression rings are Napier-style, featuring a reverse twist and taper-machined face. This innovative design duplicates the scraping edge of a positive twist torsional ring, promoting excellent side sealing and preventing oil from being forced under and behind the ring, leading to superior oil economy. For precise oil management, the oil control rings are a Three Piece Flex Vent design. This three-piece construction allows for smaller cross-sectional rails, ensuring better conformability to the cylinder bore and providing uniform pressure through four steel rails and two expanders for positive oil control. This comprehensive set includes all necessary rings for two pistons, delivering a complete solution for your 107 cubic inch engine rebuild.
