Review HASTINGS Moly Piston Ring Set .010 Inch Over For Big fits TWIN SHOVELHEAD 1980

Introducing the Hastings 2M6127010 Molybdenum Piston Ring Set, specifically designed for Harley-Davidson 80 Big Twin Shovelhead engines. This set includes four piston rings: two compression rings, one oil control ring, and one skirt or groove ring.

The compression rings, also known as the top rings, are made of molybdenum material. Molybdenum is a high-performance alloy that provides excellent compression sealing and resistance to wear and tear. These rings are also designed to minimize friction between the piston and the cylinder wall, resulting in improved engine performance and efficiency.

The oil control ring is also made of molybdenum and is responsible for controlling and regulating the flow of oil between the piston and the cylinder wall. It features a unique design with multiple grooves that help maintain an even oil film on the piston skirt, ensuring proper lubrication and reducing the risk of scuffing or scoring.

The skirt or groove rings, also known as the third ring, are located at the bottom of the piston. They are designed to prevent oil from leaking past the piston rings and into the crankcase. The molybdenum material used in these rings provides excellent sealing properties, ensuring that oil is contained within the engine and preventing unnecessary oil consumption.

This piston ring set is suitable for Harley-Davidson 80 Big Twin Shovelhead engines and is an excellent upgrade for those looking to improve their engine performance and longevity. The high-quality molybdenum material used in the construction of these rings ensures excellent sealing, reduced wear and tear, and improved engine efficiency. Installation is straightforward, and the rings come with clear installation instructions to ensure a hassle-free experience. Upgrade your Harley-Davidson engine today with the Hastings 2M6127010 Molybdenum Piston Ring Set.
