Mahle Rings Performance Gas Nitride Steel 4.140 x .043 .157 RW Plain Ring Set

Mahle OE Performance Gas Nitride Steel Piston Rings are a solid option when you're rebuilding the top end of your engine. These rings are designed to seal the combustion chamber effectively, ensuring optimal compression and preventing oil from entering the cylinder. The set includes rings with a 4.140 inch bore size, .043 inch top ring thickness, and .157 inch oil ring thickness, specifically for gas applications.

Crafted from steel and treated with a nitride finish, these rings offer improved wear resistance compared to standard cast iron rings. This nitriding process hardens the surface, making them more durable and better able to withstand the heat and pressure of combustion. They are a direct replacement for your stock rings, fitting right into the piston grooves without modification.
