About this part

Product Details

This is a Mahle MS piston ring set, designed for a 4.045 inch bore with a +.005 inch file fit. The ring set includes a 1.0mm top ring, a 1.0mm second ring, and a 2.0mm oil ring. These rings are intended for engine rebuilding projects where precise fitment is crucial.

Mahle is a well-known name in engine components, and this set is built to meet the demands of engine work. The file-fit design means you can adjust the end gap yourself, which is important for achieving proper compression and oil control, especially in modified or performance applications. This allows for a more tailored fit to your specific cylinder bore and engine build.

Remember that this ring set is not CARB approved and cannot be shipped to California. Always refer to your engine build specifications and manufacturer instructions for proper installation and gap setting.
