Mahle Rings 4.155in Bore .043in1.5MM3.00MM Plasma Moly Ductile Low Tension Reduced Rad Moly 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 is designed for a 4.155-inch bore, featuring plasma moly coated top rings that are 0.043 inches thick. The second ring is 1.5mm, and the oil ring is 3.00mm, all constructed from ductile iron with low tension for reduced drag.

These rings use a reduced radius design, which helps them seat properly against the cylinder wall. The plasma moly coating on the top rings is a tough surface that helps reduce friction and wear, especially during the critical break-in period and throughout the life of the engine. This well-built set is a solid option for anyone looking to restore their engine's compression and efficiency.
