Mahle Rings GM 396/421 63-69 Moly Ring Set

These Mahle Moly ring sets are built to the original equipment specifications for GM 396 and 421 cubic inch engines from 1963 to 1969. The moly coating on the top ring is a key feature, helping to reduce friction between the piston and cylinder wall. This not only contributes to a longer service life for your engine components but also helps minimize oil consumption, keeping your engine running more efficiently.

Mahle designs these rings with OE requirements in mind, focusing on reducing friction and ring mass. This attention to detail means you're getting a well-built set that aims to provide improved performance and durability. They are a solid option when you're rebuilding the top end of your classic GM V8, fitting a wide range of Chevrolet and Pontiac vehicles from the mid-60s.
