Piston Ring Set 4.165 1/16 1/16 3/16

The Piston Ring Set 4.165 1/16 1/16 3/16 from Hastings is a crucial component for engine rebuilds, designed for serious builders and mechanics engaged in complete engine overhauls or restorations. This set is ideal for those working on vintage performance builds or replacing worn engine components, as quality piston rings are essential for controlling blow-by, regulating oil consumption, and maintaining compression ratios that impact horsepower and efficiency.

Manufactured to OEM tolerances, this Hastings ring set ensures a precise fit for 4.165-inch bore diameter applications. It features a three-piece design with compression ring widths of 1/16 inch for the top and second rings, and a 3/16 inch oil-control ring. This design effectively manages combustion pressure and blow-by while minimizing friction loss, enhancing engine performance and longevity.

Mechanics rebuilding small-block or mid-range displacement engines will find this ring set particularly beneficial, as it is commonly used in street performance, classic muscle car restorations, and marine applications. The high-carbon steel alloys used in the rings, along with hard-anodized or chrome-plated surfaces, provide durability and extended ring life, making them suitable for modern fuel blends and longer oil change intervals.
