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

File fit rings require you to carefully file the end gap to match the specific cylinder bore of your engine. This allows for a precise fit, which is essential for proper sealing and preventing blow-by, especially in performance applications.

What are the dimensions of the rings in this set?

This set includes a top ring and second ring that are 0.0472 inches thick, and a low-tension oil ring that is 0.1181 inches thick. They are designed for a cylinder bore of 3.465 inches.

Why are these rings not CARB approved?

This particular set of piston rings is not approved by the California Air Resources Board (CARB). Therefore, it cannot be legally shipped to or installed on vehicles registered in California.

The specific dimensions of this set are 0.0472 inches for the top and second rings, and 0.1181 inches for the oil ring, with a bore size of 3.465 inches.
