Whether a ball mount shank is too small or too large to fit into a receiver tube, a CURT adapter can make up the difference. Our adapters are built with exceptional strength and designed to be precisely fitted for their application. We carry trailer hitch adapters to accommodate both receiver tube openings and shanks of 1-1/4", 2" and 2-1/2" dimensions. CURT adapters also come in various lengths to allow more clearance for a cargo carrier, bike rake or spare tire. This specialized CURT receiver adapter converts a 2-1/2" x 2-1/2" receiver tube opening to a 2" x 2" opening. It offers a gross trailer weight capacity of 4,500 lbs. and a tongue weight capacity of 450 lbs., and when combined with a weight distribution hitch, it offers 6,000 lbs. GTW and 600 lbs. TW. It also has the option to be cut down from its 34" length to 24", increasing its weight carrying capacity to 6,000 lbs. and its tongue weight to 600 lbs. When combined with a weight distribution hitch, the 24" length maxes out at 8,000 lbs. GTW and 800 lbs. TW. This hitch adapter also comes with integrated safety chain loops and an electrical bracket. All CURT adapters are constructed using our quality manufacturing processes. We CNC-form each unit, weld it together using advanced robotic systems and then mechanically descale every surface to make each adapter smooth to accept a finishing coat. To finish off this adapter, we give it a durable gloss black powder coat finish to ensure it has excellent rust, chip and UV resistance.

Worked perfectly for pulling my boat with a 2023 9-6 northern lite camper on a long box pickup.

Finally! A heavy steel item that was well-packed for shipping. I had anticipated getting a carton that looked like it had sank with the Titanic. Instead, this piece was well wrapped in a heavy gauge cardboard carton. I have not used the product as of yet. The gloss black finish is flawless and the welds look uber tight. If you are considering the purchase of this or similar hitch items, always check the weight capacity. There, my Safety Sally duty for the day. BTW, there is a dashed line showing where to cut the square tubing in order to make a 24" bar. I will be doing this.

Heavy built, purchased to use with truck camper to also pull boat. Note,: you may have to redo the drilled hole on the truck side for hitch pin insertion. The holes were not drilled square thru the tube, hitch pin would not go in all the way, hitch had to have hole spacing corrected. Be ready to do that to make it work for your truck.

This unit works great with an oversize camper on a long box PU. No issues hauling the 22’ fishing boat while hauling the oversize camper. Highly recommended for anyone looking for a longer reach for trailer clearance

I needed to extend my reach on my trucks hitch so I could tow my car trailer when my pick-up camper is on the truck. This hitch is rated for the load is well designed. It has a 'bend' in it so the connection point (2" ball) is elevated just enough so it doesn't bottom out when pulling into parking lots etc that are above the road level. Additional benefit I found is that the additional extended length actually keeps my 20' trailer within the track of my truck when turning at intersections. (ie as I turned right, the trailer shifts slightly to the left as I start the turn. I quickly became comfortable turning and manoeuvring in parking lots without needing to allow as wide 'birth' as a shorter coupled trailer.

First, let me start by this is a great product and serves it’s intended purpose. It shipped quickly, arrived safe. For me, I was under the impression that it would fit into my 2” receiver hitch, that’s on me. It. Does. Not. But because I have a welder and skills, I made it work. This unit will fit the larger 2.5” diameter receiver, but not many trucks are outfitted with them. Be aware of that before purchasing. I ended up going to the metal yard and outfitting the extension with a smaller internal square tube, welded it in after trimming back the original length and re-drilling holes to line up with my receiver standard class 3 (2”) receiver hitch.

Bought this to extend my hitch so I can load my side by side and haul my holiday trailer. I haven’t given a road test yet but it seems to be well built and I’m hoping it can handle the weight ! We will see come camping season !

Works well, fits snug in hitch (which is good so i its not wobbly). Comes in longer lengths, and cam be cut down to shorter if lengthbis not need, this will increase weight capacity. It DOES NOT come with stability straps which ARE necessary, and the metal loops are there for them so if you need to use this right away, order them at the same time. Lastly mine was missing some of its coating, which was not mentionedbin the listing. I used some black nail polish to deter rusting...

I needed an extension so I could tow my utility trailer (with my Jeep) or my boat. This adapter/extension worked great once the 2.5" receiver tube was welded on. I added side chains which stabilized the lateral movement and had no problems. Now I'm set to go fishing, boating, and off-roading. I also have a Lance 915 truck camper, which extends about 18" behind the truck. I cut some off the Curt receiver adapter so it wouldn't be too long, which allows room for the ball to extend beyond the camper's bumper. This is perfect with the 16' utility trailer, which I use to carry my Jeep, tractor, or tree trimmings from my pecan orchard. The side chains mount to the Curtis unit and then go to a bracket welded onto the tie-downs (Torklift) making a perfect triangle. No side sway & better support for the trailer. Heavy duty assembly which has been in use for a couple of years now without any issues.

I needed a long exstion for my short bed camper,and new camper. The camper is the largest short bed camper U can buy.I needed 40 inches of exstion to reach my boat trailer. I had two choses , 1 the 2" supper hitch that sold for $1200 too $1300 dallors. Or go to a class 5 2 1/2" hitch assy , with the 45048 receiver adapter. The cost of the 2 1/2" hitch and receiver adapter was $519.00 pluss safty chain and hard ware at $36.00. This system works great and was hafe the cost of a suppor hitch. I did go to a 13 inch stinger from a 10 inch. If you go this rout make sure to use the safty chain set up , it helps 75% on trailer bouncing up and down. Very happy Rob Eagle Point Or. Thank Curt Manufacturing. The change over to the class 5 hitch take about 1.25 hours.
