Mahle MS 4.070in+ .005in 1/16in 1/16in 3/16in File Fit Rings

This is a Mahle MS file-fit piston ring set, designed for universal application in engine rebuilding projects. These rings are crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. The file-fit design means you'll need to carefully adjust the end gap of each ring to match your specific cylinder bore, ensuring a precise fit and optimal performance.

This set features standard tension rings with specific dimensions: the top ring is 1/16 inch, the second ring is 1/16 inch, and the oil ring is 3/16 inch. They are also +.005 inches larger than standard, which is important to note when measuring your cylinder bore. Mahle is a well-known name in engine components, and this set is built to meet the demands of an engine rebuild where precise ring sealing is key to longevity and performance.

Remember that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for proper installation procedures and ring gap specifications.
