Mahle Rings 4.560in Bore .043in1/16in3/16in Plasma Moly Ductile Std Tension Engine Set Moly Ring Set

These Mahle OE piston rings start with a plasma moly coating on the top ring, which is a tough, wear-resistant material that helps them stand up to the heat and friction inside the cylinder. They're made from ductile iron, a strong material that can handle the pressures of combustion without cracking. This set is designed for a 4.560-inch bore and uses standard tension, meaning they're built to seal well without putting excessive drag on the cylinder walls.

The ring pack includes a specific size for the top ring (0.043 inches), a second ring (1/16 inch), and an oil ring (3/16 inch). This combination is crucial for proper engine function: the top ring handles the bulk of the sealing and heat transfer, the second ring helps with blow-by control and oil scraping, and the oil ring's job is to keep excess oil from getting into the combustion chamber. Mahle is a well-known name in engine components, and these rings are a solid option for rebuilding or repairing your engine.

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 installation procedures and torque specifications.
