The HASTINGS Piston Rings Part Number 6482070 are designed for 1200 cc Big Twin engines, offering a comprehensive set that includes top compression rings, second compression rings, and oil control rings. Crafted with precision, the top compression rings feature a barrel face and cast coating, which facilitate efficient heat transfer between the piston and cylinder wall, helping maintain optimal operating temperatures and preventing thermal damage. These rings are engineered to effectively control combustion gases, ensuring maximum power transfer from expanding gases to the crankshaft for smooth engine performance. The second compression rings utilize a reverse torsional taper face design that promotes side sealing, reducing oil consumption by preventing oil from leaking under or behind the ring. This reverse twist combined with a taper-machined face mimics the scraping edge of positive twist torsional rings, enhancing sealing efficiency. The oil control rings are three-piece flex vent types, designed with steel rails and expanders that provide uniform pressure and conformability to the bore. This design ensures effective oil regulation, minimizing oil blow-by and reducing oil consumption. Made in the USA, these high-quality rings are suitable for two pistons, with two rings per groove (except for the rails, which include two rail rings per one expander ring). Installation of these rings will help improve engine efficiency, reduce oil consumption, and promote longevity of your Big Twin engine, making them an essential component for rebuilding or restoring vintage Harley-Davidson motorcycles or similar engines.
