Wiseco 106.375mm (4.188inch) Scraper Ring Ring Shelf Stock

Wiseco is known for making high-performance forged pistons, and they develop their piston ring sets specifically to work with their pistons. This scraper ring, part number 4188FSX, is designed to ensure ultimate performance and sealing in your 4-stroke engine. The right piston rings are critical for everything from compression and sealing to controlling oil, and Wiseco rings are developed and tested to meet race-ready performance standards.

This specific ring is a scraper ring, meaning its primary job is to scrape excess oil off the cylinder walls as the piston moves down. This helps prevent oil from getting into the combustion chamber, which can cause smoking and reduce performance. It's a well-built component that plays a vital role in the overall health and efficiency of your engine's top end.
