Wiseco 102.921mm (4.052inch) Scraper Ring Ring Shelf Stock

What you get in this package is a single Wiseco scraper ring, measuring 102.921mm (4.052 inches) in diameter. This ring is designed to work specifically with Wiseco 4-stroke pistons, ensuring optimal performance and sealing. Piston rings are critical components; they handle compression, seal the combustion chamber, and control oil, so their quality directly impacts how well your piston performs. Wiseco develops and tests these rings for race-ready performance.

This scraper ring's main job is to help manage the oil on the cylinder wall. It scrapes excess oil down into the crankcase, preventing it from getting into the combustion chamber where it can burn and cause issues like smoking or carbon buildup. Getting this right is key to a healthy engine, especially in high-performance applications where Wiseco pistons are often used.
