MaxxHaul 70070 - 4000lbs 2 Inch Trailer Hitch Receiver Adapter Extender Dual Hitch Extension 10-12 Inches, Hitch Riser With 6 Inch Rise or Drop

Purchased to use with my VelociRAX 7 bike carrier and my tent trailer. I saw the reviews of some other people having the hitch break on them (after I had already made the purchase). I could not find anything out there that had stronger specs than this, so I decided to give it a try. I had to use a 4” drop on my ball mount so the ball cup would clear the bike rack. I also made a modification so I could insert my bike rack 3” further into the top receiver. My bike rack has an anti wobble bolt and I also purchased an anti wobble bracket to take the slack out of the link between the van receiver hitch and the dual receiver adapter. Lastly I used some tie downs to add some additional support and stability to the system. I assume my bike rack fully loaded weighs close to 325lbs. I am not sure if the Tongue weight limit refers to just the trailer being pulled by the lower receiver, or if it is referring to the total weight of the bike rack and the trailer tongue Weight. Nevertheless, I did not want to take any chances so the tie downs were put in place to add additional support as we went over dips in the freeway and bumps in the dirt roads.Results: 400 miles on freeways, country roads and dirt roads to City of Rocks and nothing broke or even showed signs of fatigue. After I got home I pulled it all apart and it does not look like anything even got bent. There were a few transitions on freeway overpasses that made me tense up as the 12 passenger van, 7 bikes, and a tent trailer bounced through the dips... but it all held and it made our trip a success. I will say that it takes some experimentation to get all your spacing right and on my Nissan NVP 3500, the 4” drop makes the trailer a little lower than it should be. All that being said, I’m happy with the purchase and I hope it gives me lots of years of future adventures.

This works great. I use it on the back of our camper to raise up the bike rack to avoid dragging when going over low spots.

This hitch doubler solves a very specific problem for those of us that still want to use a bike rack while towing.I have a teardrop, but I wanted to use a bike rack to free up room on the truck bed to carry other gear. Since my trailer has a long, straight beam tongue this solved my problem perfectly. The trailer weighs about 1500lbs loaded, so figure ~150lbs of tongue weight plus a little under 100lbs for the rack and bikes. This thing is more than sturdy enough for that. However, I probably wouldn't trust it with much more than that. It's held strong on many miles of highway and forest road driving, but I still wouldn't put more than 60-70% of it's rating on it just to be safe.

Built sturdy, doesn't appear to be cheaply made. Good clean welds. With this part, I can open the rear hatch on my 05 Suburban and clear the bike rack (with rack in top receiver). One negative I discovered is that with the little bit of play in the vehicle hitch receiver and the little bit of play in each of the receivers on this part, it generates a lot of wiggle room for your items to slop back and forth when turning. This is in no way the fault of the dual hitch. Any brand will do the same thing. I built some tighteners similar to the Roadmaster 061 Quiet Hitch you can buy on Amazon. The ones I built snug everthing up nicely. As in rock solid. No play whatsoever. I can only assume that the quiet hitch would do the same thing (although I have not tried one). In order for the quiet hitch to work for the top hitch, you would need to weld something on the top or bottom to act as a lip for the quiet hitch to grab on to. Other than the moving around of stuff, it's a great item. Cheaper than the big name brands and it does the same thing.

For the most part I am very happy with this two-level hitch. I use it to haul a long kayak trailer from the bottom receiver and for a bike rack on the top. It is plenty strong for that. But - it would be good to make the lower receiver stick out more beyond the top one to better allow for trailer couplers that use pop-up handles to engage the ball. This could also be done by raising the top receiver a bit more with a 1 inch longer connecting tube.I can't open and close the handle unless I maneuver the car/trailer to exactly the right hump that gives me a bit more clearance. If the trailer was a screw down type closure, it would be much easier, but that's not what I have. I would consider a straight extender for the lower receiver, but I don't need yet another pin-on joint and that would also transfer the tongue weight further back.

Very sturdy. Works perfectly.

This is very well made and works great. I have been using it all summer for my bike rack to carry heavy E bikes.

I like it and a good price
