Got a heavy-duty 3-inch receiver on your truck, motorhome, or fifth-wheel chassis and want to run a standard 2-1/2-inch shank accessory? The B&W Hitches RHXA2183 reducer sleeve drops right in so you can use your existing ball mounts, bike racks, cargo carriers, and sway control bars without buying a second hitch. No welding, no drilling -- just insert, pin, and go.
Class IV and Class V hitches with a 3-inch receiver opening are common on heavy-duty pickups, dually trucks, large Class A motorhomes, and commercial tow vehicles. The problem is that most aftermarket ball mounts, hitch-mounted cargo carriers, bike racks, and tow bars are built around the more common 2-inch or 2-1/2-inch shank standard. The RHXA2183 bridges that gap cleanly.
B&W Hitches is best known for their Turnoverball gooseneck systems and Companion fifth-wheel hitches, but their line of receiver accessories -- including this reducer sleeve -- carries the same commitment to heavy-gauge American steel. At 3.05 lbs, this sleeve is built to handle real working loads, not just light-duty accessories.
Slides into any standard 3-inch receiver opening. Accepts any 2-1/2-inch square shank accessory without modification.
Heavy-gauge steel sleeve -- not cast or stamped -- handles the lateral and vertical loads typical of Class IV and V towing applications.
Aligns with the receiver's existing hitch pin hole so your standard 5/8-inch hitch pin and clip secure both the sleeve and the inserted accessory shank.
At 5.75 inches long and 2.5 x 2.5 inches in cross section, the sleeve adds minimal protrusion beyond the receiver face.
The RHXA2183 reduces the receiver opening from 3 inches down to 2-1/2 inches. This lets you use accessories with a 2-1/2-inch square shank in a 3-inch receiver. It does not reduce down to the more common 2-inch shank size -- for a 3-inch to 2-inch reduction, you would need a different sleeve. If your accessory shank is 2-1/2 inches square, this is the correct part.
Three-inch receiver hitches are found on the following types of vehicles and applications:
If your receiver opening measures 3 inches square inside, this is the correct reducer for 2-1/2-inch accessories.
Measure the inside dimension of the receiver tube opening (not the outside of the hitch). A 3-inch receiver measures approximately 3 inches square on the interior. A standard full-size truck receiver measures 2 inches, and a mid-size receiver measures 1-1/4 inches. If your inside measurement is 3 inches, you need this sleeve for 2-1/2-inch shank accessories.
Installation is straightforward -- no tools are required beyond a standard hitch pin:
B&W offers a full line of receiver accessories to complement this sleeve, including pintle hook adapters, receiver-mounted ball mounts, and their signature Turnoverball gooseneck systems. For 3-inch to 2-inch reductions or other configurations, check additional B&W reducer and adapter part numbers to confirm the correct fit for your shank size.
