About this part

Product Details

Mahle is known for making solid OE replacement parts, and these performance top rings are no exception. If you're rebuilding an engine with a 4.250-inch bore, these rings are built to perform. They feature a plasma-moly coating on the top ring, which is a common upgrade for better wear resistance and sealing.

The top ring is 1.0mm thick, and the overall ring set is designed for a 4.250-inch bore. The HVOF (High-Velocity Oxygen Fuel) application of the moly coating helps it bond strongly to the steel, creating a durable surface that works well against the cylinder wall. This type of coating is often chosen for its ability to handle heat and friction effectively, helping to maintain good compression and oil control.

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