Not going to fit in your standard 2” receiver hitch
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.

Increases hitch reach
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...

Extension for my F250 Hauling a 2005 Lance 845 Truck Camper
My original hitch extension broke on me so I had to order another one. I have a 2005 Lance Model 845 truck camper that sits well past my rear bumper. I ordered this one and had it on my front porch within two days. Love amazon Prime. The 34" length was a little to long for the extension and had to cut it down to 24" for it to barely go past my campers bumper. I used a circular saw with a metal cutting blade I bought at Home Depot for $3. After two minutes of cutting, I had the hitch extension but down to 24". I placed it in my 2 1/2 inch receiver on my Ford F250 and it works like a charm. I haul a 21 ft pontoon with the extension and sometimes a little utility trailer. Great product.

This adapter/extension worked great once the 2
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.

Made solid, drilled hole(s) not centered when it was manufactured.
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.

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

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.

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

Well made, rock solid! Nice extension, very practical to stretch that trailer another foot or two to carry long lumber.
