Mahle Rings 4.155in Bore .043in 3/16in Plasma Moly Duct Std Tension Reduced Radial Moly Ring Set

Mahle is known for making OE-quality engine components, and this set of piston rings is no different. If you're rebuilding an engine and need to ensure a good seal between the piston and cylinder wall, these rings are a solid choice. They're designed for a 4.155-inch bore and feature plasma moly duct construction for durability.

These rings use standard tension and have a reduced radial design, which helps them seat properly in the cylinder bore. The plasma moly coating on the top ring is a tough material that helps reduce friction and wear, contributing to a longer life for both the rings and the cylinder walls. This is important for maintaining compression and preventing oil from getting into the combustion chamber.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
