Hastings Replacement Piston Rings for 3.750" Bore

Ensure peak engine performance and longevity with the Hastings Piston Rings set, meticulously engineered for a 3.750" bore. This comprehensive set provides everything needed for a complete piston ring replacement, delivering superior sealing and oil control for your motorcycle engine.

Description

The Hastings Piston Rings set is a premium replacement solution designed to restore optimal compression and efficiency to your engine. Each set includes top compression rings, second compression rings, and oil control rings, specifically manufactured for a 3.750" bore. The Moly Coated ring material ensures enhanced durability and reduced friction, crucial for high-performance motorcycle engines. The top compression rings feature a Barrel Face design, essential for efficient heat transfer between the piston and cylinder wall, while effectively controlling combustion chamber gases to maximize power 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, actively promoting side sealing to prevent oil from being forced under and behind the ring, thereby significantly improving oil economy. For superior oil control, the set includes Three Piece Flex Vent oil control rings. Their three-piece design allows for rails with a small cross-sectional area, ensuring better conformability to the cylinder bore and providing uniform pressure through four steel rails and two expanders for consistently positive oil management. Proudly Made in the USA, this Hastings piston ring set offers uncompromising quality and precision engineering for demanding motorcycle applications.
