Mahle Rings Performance Metric HV385 81.0MM x 1.0MM/1.2MM/2.8MM Drop In Std Tension Moly Ring Set

With a 1.0mm top ring, 1.2mm second ring, and 2.8mm oil ring, this Mahle HV385 set is built for 81.0mm bore engines. The moly coating on the top ring helps reduce friction and wear, which is important for keeping your engine running smoothly over time. These are standard tension rings, meaning they offer a good balance of sealing ability and reasonable cylinder wall pressure, making them a solid choice for many rebuilds.

Mahle is a well-known name in engine components, and this set is designed as a direct drop-in replacement for stock applications. The moly coating is a practical detail that helps with initial break-in and extends the life of both the rings and the cylinder walls. If you're rebuilding the top end of your engine and need a reliable set of piston rings, this Mahle set is a popular option.
