Product Details

This set includes the piston rings you need for a rebuild of your Ford 2.3L engine. These are the Mahle OE rings, designed to meet the original equipment specifications for a wide range of Ford and Mercury vehicles from the mid-70s to mid-80s. They are built to reduce friction and oil consumption while providing a solid service life.

Mahle has a reputation for advanced piston ring technology, and these rings are no exception. They are engineered to minimize friction, which can help improve engine efficiency, and also help control oil consumption, keeping your exhaust cleaner. The rings are 0.030 inch undersize, meaning they are intended for engines where the cylinder bores have been honed or bored out to that specific size during a rebuild. This ensures a proper seal between the piston and cylinder wall.

This set is designed for a direct fit on many Ford and Mercury models, including popular vehicles like the Ford Mustang, Pinto, and Ranger, as well as the Mercury Capri and Bobcat. Always refer to your vehicle's specific service manual for detailed installation procedures and specifications.
