Mahle Rings Performance 4.470in x 1/16in HV385 Steel UCR .190in RW Moly Ring Set

Mahle OE is known for making reliable engine components, and this particular piston ring set, the HV385, is a good example of their work. These rings are designed to fit pistons with a 4.470-inch bore and feature a 1/16-inch top ring, a 1/16-inch second ring, and a 0.190-inch oil ring. The construction uses steel for the top ring with a Moly face, which helps with wear resistance and proper sealing against the cylinder wall.

The UCR designation means these are a unique compression ring design, and the RW indicates a specific oil ring type. This set is built for performance applications where a strong seal is important for maintaining compression and controlling oil consumption. When you're rebuilding an engine, getting the right piston rings is crucial for its long-term health and performance, and this Mahle set offers a well-built option.

Please note that this ring set is not CARB approved and cannot be shipped to California. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
