JE Pistons Ring Sets 017-1/16-3/16 RINGS

JE Pistons has a long history of making top-tier engine components, especially for racing applications. This file-fit piston ring set is built with that same attention to detail, designed to help your engine breathe and seal better. The set includes a D017 inch ductile iron plasma moly top ring, a 0.064 inch iron phosphate second ring, and a 0.188 inch carbon steel chrome standard tension oil ring. These rings are crucial for sealing combustion pressure, which directly impacts how much horsepower your engine can make and how efficiently it runs.

Because these are file-fit rings, they give you the flexibility to achieve a perfect seal in your specific cylinder bore, a common practice in performance engine builds. JE Pistons uses the same techniques for these rings that you'd find on professional race engines in NHRA Pro Stock and NASCAR, aiming for improved durability and reduced friction for more power. While these rings are designed for maximum performance, please note they are not CARB approved and cannot be shipped to California.
