Product Details

Mahle OE is known for making technically advanced engine components that meet strict original equipment requirements. This Moly Ring Set, part number 40668CP.060, is designed for AMC 199, 232, and 258 cubic inch engines, Buick 225 cubic inch engines from the mid-60s, and a wide range of Jeep vehicles from 1964 through 1988. These rings are built to help minimize oil consumption and reduce friction, contributing to a longer service life for your engine.

This set features moly-coated top rings, which are a popular choice for their ability to reduce friction and improve wear resistance, especially in engines that see regular use. The advanced design aims to provide a good seal between the piston and cylinder wall, which is crucial for maintaining compression and preventing blow-by. Mahle focuses on the latest piston ring technology to ensure these rings perform well and last.

When rebuilding or refreshing an engine that fits this application, like a Jeep CJ or an AMC Gremlin, these rings are a solid option. They are designed to fit right and function as intended, helping to restore or improve your engine's performance and efficiency.
