Mahle MS 4.350in+ .005in 1/16in 1/16in 3/16in File Fit Rings

If you're rebuilding an engine and need to get the piston ring end gap just right, this Mahle MS file fit ring set is a solid option. These rings are designed so you can precisely file the end gap to match your cylinder bore, which is crucial for proper sealing and compression.

This set features a common 1/16 inch top and second ring size, paired with a 3/16 inch oil ring. They're intended for a standard tension application and come at a +.005 inch oversize, meaning you'll need to file them down to achieve the perfect fit for your specific cylinder bore. Mahle is a well-known name in engine components, and these rings are made to hold up in a rebuilt engine.

Remember, these rings are file-fit, so you'll need the right tools and a steady hand to set the end gap correctly. It's a good idea to check the manufacturer's recommendations for your specific engine build to determine the ideal end gap clearance.
