Mahle Rings 4.155in Bore .043in1/16in 3.00MM Plasma Moly Ductile Low Tension Reduced Moly Ring Set

Mahle is known for making well-built engine components, and this piston ring set is no exception. If you're rebuilding an engine and need a reliable set of rings, these are a solid option. They're designed for a 4.155-inch bore and feature a specific ring configuration: the top and second rings are .043 inches wide, while the oil control ring is 3.00mm. This setup is engineered for low tension and reduced tension, which helps improve efficiency and reduce drag inside the cylinder.

The plasma moly coating on the top and second rings is a notable detail. This tough coating helps them resist wear and friction against the cylinder wall, especially important in engines that see regular use. The ductile iron construction of the oil control ring also adds to its durability and ability to seal effectively. These rings are designed to work well in many engine builds where a balance of performance and longevity is key.
