Mahle Rings Performance HV385 Steel Top 3.759 x 1.2MM .133RW Moly Ring Set

If you're rebuilding the top end of your engine, a solid set of piston rings is crucial for proper sealing and performance. This Mahle OE Moly Ring Set is designed to help restore compression and keep oil where it belongs. The steel top ring is built for durability, while the moly coating helps reduce friction and wear, especially during the break-in period. These rings are made to fit pistons with a 3.759 inch bore and feature a 1.2mm top ring groove and a 3mm oil ring groove.

Mahle is a well-known name in engine components, and this set is a popular choice for many engine builders. The moly coating on the top ring is a notable feature that helps ensure a good seal against the cylinder wall from the start. It's important to note that these rings are not CARB approved and cannot be shipped to California.
