Mahle Rings FRD/GM V8 56-67 Plain Ring Set

These Mahle piston rings are 0.030 inch undersize, meaning they are designed to fit pistons that have been bored out by 0.030 inches during an engine rebuild. They are built to meet original equipment requirements, focusing on reducing friction and minimizing oil consumption for a longer service life. This set is intended for a wide range of V8 engines from Ford, Mercury, Lincoln, and some Oldsmobile models produced between 1956 and 1967, including popular vehicles like the Ford F-100, Ford Galaxie, and Mercury Monterey.

Mahle's approach to piston ring technology aims to improve engine efficiency and durability. By carefully managing ring mass and friction, these rings help ensure proper sealing between the piston and cylinder wall. This is crucial for maintaining compression, controlling oil levels, and ultimately contributing to the overall health and performance of your engine. They are a well-built option for anyone rebuilding a compatible V8 engine from this era.
