Mahle Rings 4.020in Bore 1/16in 3.00MM Plasma Moly Ductile Std Tension Engine Set Moly Ring Set

Mahle is well-known for making solid engine components, and this piston ring set is no different. If you're rebuilding an engine with a 4.020-inch bore, these rings are built to get the job done. They feature a plasma moly coating on the top ring, which is a tough material that helps reduce friction and wear against the cylinder wall. The middle and oil rings are made from ductile iron, offering good strength and sealing performance.

This set uses standard tension rings, which are a common choice for many engine builds. The combination of plasma moly and ductile iron means you're getting a well-built set that's designed to seal well and last. When you're putting an engine back together, good piston rings are crucial for proper compression and oil control, and this Mahle set is a popular option for that.
