Mahle Rings Performance Metric HV385 90.0MM x 1.0MM/1.2MM/2.8MM Drop In Std Tension Moly Ring Set

This set gives you the piston rings you need for a standard rebuild. You get the top compression ring, second compression ring, and oil control ring, all designed to fit pistons with a 90.0mm bore. The rings feature a moly coating for improved durability and reduced friction, and they're set up for standard tension, meaning they're not overly tight or loose for most engine applications. These are a drop-in replacement, so they're made to install without needing special modifications to your pistons or cylinders.

Mahle is a well-known name in engine components, and this set is built to meet the needs of a performance metric application. The specific dimensions of 1.0mm for the top ring, 1.2mm for the second ring, and 2.8mm for the oil ring are common for many metric engines, ensuring a good seal against the cylinder wall. Using moly-coated rings helps them seat properly and maintain that seal over time, which is important for consistent engine performance and oil control.
