Mahle Rings 4.030in Bore .043in 3.00MM Plasma Moly Ductile Std Tension Reduced Rad Moly Ring Set

When you're rebuilding the top end of your engine, getting the piston rings seated properly is critical for compression and oil control. This Mahle OE ring set is designed for a 4.030 inch bore, a common size for many performance and rebuild applications. They feature plasma moly ductile top rings, which are known for their durability and ability to handle heat, paired with reduced tension oil rings to help manage oil consumption.

Mahle has been a trusted name in engine components for a long time, and this set reflects that. The ductile iron construction of the top rings offers good strength, while the plasma moly coating on the face helps reduce friction and wear against the cylinder wall. The standard tension design ensures a solid seal against the cylinder bore, which is essential for maintaining good compression and preventing blow-by. These rings are a solid option for anyone looking to put a fresh set of pistons into their engine build.
