What Part Do I Need to Reduce My Curt 2-1/2 Inch Hitch to a 2 Inch Opening

Question:

What is the inside diameter and outside diameter of this part? Is it 2.5 inches OD and will it fit as a sleeve for a class 5 hitch to reduce to a 2.0 inch ID Class 4 hitch?

We do offer a reducer that will allow you to use a Class III or IV accessory in a Class IV 2-1/2 inch receiver. The Curt Reducer Sleeve, part # C45405 would work well for you. The outside dimension is just a bit less than 2-1/2 inches, to allow for easy installation and removal. The inside dimension would be a bit larger than 2 inches to allow easy installation and removal of the hitch accessory.

Ford OEM 2-1/2 inch receivers have a tighter/different radius on their 2-1/2 inch receiver tubes. To accommodate the OEM Ford 2-1/2 inch hitch, the corners of a ball mount, shank or reducer sleeve may need to be sanded down to slide into the hitch. Do not remove any more material than necessary. Simply removing the paint or powder-coat is often sufficient. Never use a grinder to knock-down the corners, which may remove too much material and will also heat the accessory and could compromise the product's structural integrity. This is especially the case with cast accessories like larger weight distribution shanks.
