Mahle Rings 4.160in Bore Dia 1/16in PC479 Top Rings Plain Ring Set

This is a set of Mahle OE top piston rings, designed for a 4.160-inch bore diameter. These rings feature a 1/16-inch face width and a plain ring design, part number PC479. They are a direct replacement for your engine's original top rings, crucial for sealing the combustion chamber and managing oil.

Mahle is a well-known name in engine components, and these rings are built to meet the specifications of original equipment. The plain ring design is a common and effective type for many engine applications, ensuring a good seal against the cylinder wall. Proper ring seal is essential for maintaining compression, preventing oil from entering the combustion chamber, and helping to dissipate heat from the piston.

When rebuilding or refreshing an engine, using quality piston rings like these from Mahle OE is important for the longevity and performance of your motor. Always refer to your vehicle's specific service manual for proper installation procedures and torque specifications.
