Mahle Rings Performance Gas Nitride Steel 4.115 x .043 .157 RW Plain Ring Set

When you're rebuilding the top end of your engine, especially for a performance application, the piston rings are critical. This set from Mahle OE is built with nitride steel, a material known for its strength and resistance to wear, which is important for maintaining a good seal under higher cylinder pressures. The 4.115 inch bore size and .043 inch ring thickness are specific dimensions to ensure they match your pistons correctly.

The nitride treatment on these rings helps them hold up better to the heat and friction found in performance engines. This means they can help maintain a solid seal between the piston and cylinder wall, which is key for both power output and oil control. Mahle OE is a well-known name in engine components, and this set is a solid option for anyone looking to get their engine back in top shape with reliable parts.
