Mahle Rings Buick 305 5.0L Eng 77-91 Checker 305 5.0L Eng 78-80 Chevy 305 Plain Ring Set

This is a set of Mahle OE 0.040 inch undersize piston rings. These rings are designed to help minimize engine oil consumption, reduce friction, and provide a longer service life for your engine. They are built to meet original equipment requirements, meaning they are made to the same standards as the parts that came with your vehicle from the factory.

Mahle is known for making technically advanced engine components. These piston rings are a solid option if you're rebuilding the top end of your engine and need reliable replacements. The 0.040 inch undersize specification means they are intended for use with pistons that have also been machined to be 0.040 inches smaller than their standard size, typically used when the cylinder bore has been honed out to correct wear.

This set fits a wide range of vehicles equipped with the 305 5.0L engine, including many Buick, Chevrolet, and Cadillac models from the 1970s through the 1990s. Always confirm fitment for your specific vehicle.
