Mahle Rings Performance Steel Napier 2nd Ring 3.909in x 1.0MM .136in RW Plain Ring Set

If you're rebuilding the engine in your vehicle, getting the right piston rings is crucial for proper sealing and performance. This set from Mahle OE features steel Napier 2nd rings, designed to help maintain a good seal against the cylinder wall. The Napier hook design on the second ring helps to scrape oil on the downstroke and seal compression on the upstroke, contributing to a well-functioning engine.

These rings are made from steel and measure 3.909 inches in diameter with a 1.0mm top ring groove and a 1.36 inch ring height. Mahle OE is a well-known name in engine components, and this set is built to meet the needs of a performance-oriented rebuild. They are a plain ring set, meaning they don't have special coatings, but their steel construction and Napier design offer reliable performance for many applications.
