Mahle MS 3.776in +.005in 1.0mm 1.0mm 2.0mm File Fit Rings

This Mahle MS piston ring set gives you the components needed for a custom engine rebuild. You get a set of file-fit rings, with a 1.0mm top ring, a 1.0mm second ring, and a 2.0mm oil ring. These are designed for builders who need to precisely set their ring end gaps to match specific engine clearances.

Mahle is a well-known name in engine components, and this set is built to their standards. The file-fit design means you'll need to carefully measure and file the end gaps to achieve the correct fit for your pistons and cylinder bore. This approach allows for very specific tuning of your engine's sealing and oil control, especially important when working with modified or performance engines where standard rings might not offer the exact clearance needed.

Remember, 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.
