Product Details

If you're rebuilding the engine in your classic Buick, Dodge, or Plymouth, getting the right piston rings is key to a solid rebuild. These Mahle Moly Ring Sets are built to meet the demands of original equipment, focusing on reducing friction and minimizing oil consumption. That means a healthier engine that runs smoother and lasts longer.

Mahle has a reputation for bringing advanced piston ring technology to the table. These rings are designed to work with your pistons to create a tight seal in the cylinder bore. This seal is crucial for proper compression, which directly impacts how much power your engine makes and how efficiently it burns fuel. The moly coating on these rings helps them seat quickly and reduces wear, especially during the critical break-in period, contributing to their overall service life.

This set is designed for a range of classic V8 engines, including those found in the Dodge Challenger, Plymouth Barracuda, and Buick Gran Sport. Make sure to check the fitment details to confirm compatibility with your specific vehicle.
