What does 'file-fit' mean for these piston rings?

File-fit rings have an end gap that you must adjust yourself by filing the ends to the correct specification for your engine's cylinder bore. This allows for a precise fit and optimal sealing.

What are the ring dimensions?

This set includes 1.0mm width for the top and second compression rings, and a 2.0mm width for the oil control ring. The bore size is 3.830 inches, with a +.005 inch oversize.

Can these rings be shipped to California?

No, this part is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

This is a Mahle MS 3.830 inch piston ring set, specifically the file-fit type with a +.005 inch oversize. These rings are designed for engine rebuilding applications where precise fitment is crucial. The set includes rings with face widths of 1.0mm for the top and second rings, and 2.0mm for the oil ring, offering standard tension for reliable sealing.

Mahle is a well-known name in engine components, and this ring set is built to meet the demands of an engine rebuild. The file-fit design means you'll need to gap the end of each ring to achieve the exact clearance required for your specific cylinder bore. This allows for a more customized and potentially better-sealed piston assembly compared to pre-gapped rings, especially in custom or performance engine builds. Ensure you have the proper tools and knowledge for gapping piston rings before installation.

Please note that this part is not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for detailed installation procedures and specifications.
