About this part

Product Details

If you're rebuilding the top end of your engine, a fresh set of piston rings is essential for proper sealing and performance. These Mahle OE Performance Gas Nitride Steel rings are designed to replace your worn-out originals, helping to restore compression and prevent oil from getting into the combustion chamber. They feature a nitride steel construction, which offers good durability for the demanding environment inside a cylinder.

The rings measure 4.150 inches in bore size with a thickness of .043 inches for the top and second rings, and .157 inches for the oil ring. This specific configuration is often used in performance applications where a tight seal is critical. Mahle is a well-known name in engine components, and these rings are made to fit right into your existing pistons.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for proper installation procedures and torque specifications.
