Hastings Piston Ring Set for +0.020" Oversize Bore

Optimize your engine's performance and longevity with the Hastings +0.020" Piston Ring Set. Engineered for precision and durability, this replacement set provides everything you need for a robust engine rebuild, ensuring superior sealing and efficient power transfer.

Description

Designed as a direct replacement, this Hastings +0.020" Piston Ring Set is crucial for restoring your engine's compression and oil control. Each set includes top compression rings, second compression rings, and oil control rings, meticulously crafted to meet demanding performance standards. The Moly Coated ring material reduces friction and enhances wear resistance, contributing to a longer engine life. The top compression rings feature a Barrel Face design, optimizing heat transfer between the piston and cylinder wall while effectively controlling combustion chamber gases. This allows the piston to efficiently transfer the energy of expanding combustion gases to the crankshaft, maximizing power output. The Napier design of the second compression ring, with its reverse twist and taper-machined face, promotes superior side sealing. This innovative design prevents oil from being forced under and behind the ring, leading to better oil economy and reduced consumption. Furthermore, the three-piece Flex Vent oil control rings are engineered with a small cross-sectional area for exceptional conformability to the cylinder bore, providing uniform pressure through four steel rails and two expanders for positive oil control. Proudly Made in the USA, this piston ring set is a testament to quality and reliability for motorcycle enthusiasts and professional mechanics.
