Mahle Rings Perf 4.075in x 1/16in .190in RW Plasma Moly Steel UCR Chrome Ring Set (48 Qty Bulk)

If you're rebuilding the engine in your performance vehicle, getting the right piston rings is crucial for sealing and power. This Mahle OE set is built for engines with a 4.075-inch bore, featuring a 1/16-inch top ring and a 0.190-inch oil ring. They're designed to ensure a solid seal between the piston and cylinder wall, which is key for compression and preventing oil from entering the combustion chamber.

These rings are constructed from plasma moly steel, a well-built material known for its strength and resistance to wear, especially under demanding conditions. The UCR (Under Crown Ring) design and chrome plating on the top ring help them stand up to the heat and friction found in performance applications. This bulk set includes 48 rings, making it a practical choice for shops or builders working on multiple engines or a large project.
