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 a complete ring kit engineered for 8-cylinder engines requiring precision replacement or performance rebuilds. Manufactured by MAHLE Original/Clevite under part number 3150036.030, this piston ring set features a 4.030-inch bore size and plasma-moly coating for enhanced durability and reduced friction in high-demand engine applications.

The ring configuration—1/16-inch compression ring, 1/16-inch second compression ring, and 3/16-inch oil control ring—delivers standard tension performance across the piston ring set. Plasma-moly coating provides superior wear resistance and reduces blow-by in both street and performance engine environments. This steel construction withstands high cylinder pressures while maintaining consistent ring seal throughout the engine's operating range. The drop-in design ensures straightforward installation into compatible 8-cylinder engines without custom fitting or modification.

Engine rebuilders, performance shops, and serious enthusiasts rely on MAHLE Original piston rings for restorations, upgrades, and high-mileage engine rebuilds. Whether you're reconditioning a worn engine block or maximizing compression and efficiency in a modified platform, this piston ring set delivers the factory-grade quality and precise tolerances required for reliable long-term operation. The 4.030-inch bore specification matches many classic and modern V8 platforms that have been bored or are running overbore specifications.

MAHLE Original is recognized throughout the automotive rebuilding industry for OEM-quality components and strict manufacturing tolerances. This piston ring set is engineered to the same specifications as factory equipment rings, ensuring compatibility and performance across a wide range of 8-cylinder engine platforms. Proper installation with correct gap spacing and ring seating procedures is essential to achieve optimal compression and minimize oil consumption.
