Mahle Rings GMC Pass 400/ 428 Engs 1975-79 Moly Ring Set

These Mahle Moly piston rings are built to a 0.060 inch oversize, designed to reduce friction and minimize oil consumption in your engine. They are constructed with Moly (molybdenum) coating, which is known for its ability to handle heat and reduce wear, helping to extend the service life of your engine components. This set is engineered to meet the demanding requirements of original equipment manufacturers, ensuring a solid performance upgrade for your rebuild.

Mahle has a reputation for creating technically advanced piston rings, and this set is no exception. They focus on reducing both friction and the mass of the rings themselves, which contributes to better engine efficiency and responsiveness. This means you're getting a well-built part that's designed to perform reliably and last longer, even under regular use. This set fits a wide range of GM V8 engines from the mid-60s through the late 70s, including popular models like the Pontiac Firebird, Oldsmobile Delta 88, and Buick LeSabre.
