Mahle Rings Ford 429/460 7.5L Engs 68-78 Ford Trk 429/460 7.5L Engs Moly Ring Set

This is a Mahle OE Moly Ring Set, part number 40843CP.040. You get a complete set of piston rings designed for Ford 429 and 460 cubic inch, 7.5-liter engines from 1968 through 1978, commonly found in Ford trucks and various car models. These rings are crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall.

Mahle developed these rings with a focus on reducing friction and minimizing engine oil consumption, which helps extend the overall service life of your engine. The moly coating on these rings helps with initial seating and provides a durable surface for consistent performance. They are built to meet original equipment requirements, meaning they are designed to fit and function just like the factory rings.

This set is a solid option for anyone rebuilding or refreshing their Ford 429/460 engine. Remember that these rings are 0.040 inches undersize, so ensure your cylinders are bored to match this specification before installation. Always refer to the manufacturer's installation instructions for precise details.
