Mahle Rings Performance Metric HV385 81.5MM 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 Piston Ring Set (part number 3150209) is built for a standard 81.5mm bore. The moly coating on these rings helps reduce friction and wear, which is crucial for engine longevity and performance. These are standard tension rings, meaning they offer a good balance of sealing and durability for many common engine rebuilds.

Mahle is a well-known name in engine components, and this set is designed as a direct replacement for your engine's original rings. The drop-in design means they should fit right into your pistons without modification, making the rebuild process smoother. Proper ring seal is essential for maintaining compression, controlling oil consumption, and ensuring your engine runs efficiently.
