Piston Ring Set 4.030 Moly 1/16 1/16 3/16

The MAHLE Original Piston Ring Set 4.030 Moly 1/16 1/16 3/16 is designed specifically for engine rebuilders and performance mechanics working with bore sizes up to 4.030 inches. This set is ideal for both stock engine refreshes and high-output builds, ensuring optimal performance and reliability.

These moly-coated piston rings effectively seal combustion pressure, control blow-by, and regulate oil consumption. The 1/16-inch top and second rings, along with a 3/16-inch oil control ring, provide a proven compression and durability profile. Molybdenum coating enhances scuff resistance and reduces friction, facilitating quicker ring seating during break-in.

This piston ring set is compatible with any stock or stroker build utilizing 4.030-inch pistons, making it suitable for a range of applications from classic small-blocks to modern performance engines. For optimal results, verify bore diameter and ring end-gap clearance before installation to ensure maximum compression and longevity.
