Works great on my Jeep Cherokee. Beefed it up a little to facilitate 450 + pound cargo weight on upper


The hitch extender adapter arrived a day early and will allow me to use my bike rack while towing my trailer. If I do not bring the bike rack, the extension will allow the tail gate on my 2017 Silverado to be lowered without hitting the trailer tongue jack with the trailer hitched to the truck. Also the rated max towing weight of 3500 lbs with the extender is adequate for my needs, since the gross vehicle weight of my trailer is only 3000 lbs.

Be aware that using this extender will LOWER the capacity both the towing and the tongue weight capacity of your hitch by half.


I bought one from Harbor Freight first and returned it because the fit was sloppy. This one was about the same. However even worse was that it had been dropped and had multiple chips out of the black finish. I had no idea it would include a hitch pin.

You mentioned that the adapter was still sloppy and I wondered if you meant that it was loose in the receiver. If that is the case, then using an anti-rattle device like part # RM-061 will help. I will also have our Customer Service team reach out to you about the chipped paint. I recommend touching up the extender with a rust resistant paint to help protect against rust.


I have a Ford Flex and needed a hitch receiver adapter solution for my bike rack to mount higher from the ground and away from back hatch. After shopping locally at a few shops without success I went to google and discovered etrailer & desired product within 5 minutes. Three days later I had my double receiver and couldn’t be happier. Great product and great service. Thank You, etrailer.


Product did what it is supposed to. I would have liked the product to have been able to have a higher weight tolerance. Also, the designers need to look into making a product with a higher second mount. If a trailer is towed, the second mount needs to be much higher to have clearance for bikes, etc.

Product has held up for couple hundred miles. We will be using it for a trip of several hundred more miles.


Easy to assemble, solid construction. I connected it to the after market trailer hitch that I bought on etrailer no problem. Since my after market trailer hitch is located low, I had to purchase the Curt Dual Hitch Extender which raised the cargo trailer to avoid a low clearance. Worked well.


Got the Dual Receiver hitch quickly and it works great. It serves two purposes. One as advertised to tow a trailer and connect a bike rack or cargo case. Second, while we are camping in our 1978 Vintage lifted Blazer the Dual Receiver, is turned upside down and a RHS2 two step Hitch Stair is put in the lower tube and it lowers the step to a usable normal step to get into the Blazer...both units work perfectly. I hope there is a way to add a picture from a future camping trip to show everyone.


I recently purchase a riser for my 2018 Toyota Rav4. I found the product to be of excellent quality and met my expectations. I will be using it both to tow my boat trailer and to attach my cargo carrier or bike rack. When going over a steep driveway my cargo carrier would bottom out. This riser eliminated this problem. Although I opted for the standard shipping. etrailer expedited the shipment at no additional cost to me. etrailer stood behind this product and I would recommend doing business with this company.


Works great - we are able to tow our boat trailer and our hitch mounted bike rack at the same time!
Also GREAT customer service for helping us figure out what we needed!


I ordered this product to be able to tow a car and haul 4 bikes on a bike rack. I used it first on a camping trip 150 miles away. The product works as advertised. I towed a Pontiac Grand Am and caried 4 heavy mountain bikes with no problem. I did have to get longer chains and an extension for the electrical hookup for the tow dolly (the extender adds about 8 inches). I was initially worried about clearence between the bike rack and the car but that turned out not to be a problem at all and could have addded a fifth bike easily. I probably had 150 pounds of bikes plus about 100 to 125 pounds of tounge weight from the Grand Am on a tow dolly. This is close, but still under the limit of the product and had no issues while driving across some very bumpy roads. It was worth every penny not to have to drive a motor home and car seperately. It will certainly pay for itself on longer trips.


Purchased this multi-hitch after being informed a separately ordered product wouldn't be in on time. Customer service Michelle S and Nicky K) were outstanding in helping me cancel my prior order and replacing it with the multi-hitch. They even expedited shipping knowing I needed it for a trip. This is my fifth time purchasing with eTrailer and I've never been disappointed. The product selection is excellent, prices cannot be beat and the customer service is the absolute best in the business.


Exactly what I needed for my motor home. I'm able to carry a receiver hitch bike rack with bikes and still tow my car. Works extremely well. This dual receiver is built very well. One point. For my needs, I also purchased anti-rattle locking bolts to take the "play" out of the hitch connections to stabilize the bike rack. They perform exactly as advertised. The bikes are very stable on the hitch except where the dual receiver mounts to the original receiver. Since the dual receiver is built so well, the "male" end is solid steel and not hollow. Therefore, internal locking bolts cannot be used. An external anti-rattle device is required at this connection and they are harder to find.


Thank You for making my life much easier, especially when I am in need of anything pertaining to Trailering !

All products that I ordered from you came in Excellent condition (packaging).

The Hitch extension and Hitch Receiver Locks fit like a champ and were an easy install!
Pictures to follow.

It’s perfect for towing our sailboat while also carrying our bike rack. This hitch is heavy duty, well designed, and inexpensive. I’d definitely recommend it for boats or trailers. I paid the lowest shipping charge but the company shipped it with a faster carrier and I received it within only a few days.


First, I know that processing and shipping comments are taboo, but I am truly amazed at how you got this to me so fast.

Our problem was that we both kayak and bike. We have a trailer for the kayaks and a hitch rack for the bikes. We've only been able to take one or the other. Of course the logical idea is to get a dual receiver, but that didn't work because many duals offset the top receiver several inches to the rear, putting the bike rack into the front of the boats. This one, by having "even" openings, is a more excellent choice.

But still not done. The bikes STILL sat too far aft and would STILL hit the boats, not directly, but when turning. So we also purchased an 18" extender for the bottom trailer opening. Now we have plenty enough space to allow for transporting everything! Bring on the recreation!


Overall, this is exactly what I needed. The only reason that it's not Excellent is because the weld seam between the front and read of the hitch is approximately 1/2". This causes the receiver not to line up with the hitch receiver unless you're able to "lengthen" receiver holes.


Great product. Well made. Exactly what I needed. Arrived in two days, before promised. Thanks for the quick service.


Does what it is supposed to do. Allowed me to install my 2" bike rack on my 2017 Sienna higher off the ground to prevent it from scraping on the ground.


This hitch adaptor fits the need: bike rack on top and spare tire below. It has a huge flaw though - the design allows it to rattle. Which really shows it's ugly head once you load it. The engineers should be called to the carpet on this one. Guys lines are nearly mandatory using this hitch adaptor.


I have a hitch mounted winch that I need to use occasionally to winch various things on to a flat bed trailer. The Curt Dual receiver was a great solution for me! I can also use with my hitch mounted bike carrier when traveling.
etrailer had the receiver in stock and shipped the same day. Great service!


The Curt dual 2" receiver extension appears to be of high quality. It does the job of getting my carrier above the exhaust pipes.

The Erikson retractable ratchet straps also appear to be very easy to use to keep cargo in my carrier secure.


We were thrilled to receive our hitch today after ordering it three days ago. We have towed boats and horse trailers for thirty years. We have just purchased a new Class A Motorcoach and wanted to find out how to Best load two bikes and tow a Mini Cooper at the same time. We did not want to use the ladder for the bikes. My husband had seen a product like this and knew it was exactly what we wanted. I tracked it down and we can’t wait to get everything all loaded up. Based on our experience it is obvious that this is a high quality durable product. These guys are great to work with too. Very refreshing.


I use this Curt adapter to raise a cargo box for more ground clearance off-road. I works well for that, at the cost of pushing the box further out away from the vehicle. But it works, and is the shortest I've found in that regard. It isn't rusting after one year either, which shows the quality of the paint.


This is exactly the hitch I was looking for to accommodate travelling in my Tacoma with a tandem kayak as well as a Yakima bike rack for two bikes. It actually saved me from buying a multi-sport trailer which can limit the possibilities of parking in limited areas to take advantage of secluded biking and kayaking venues.


Excellent product if you’re towing but still want a bike rack that needs a receiver hitch.

  • Bike Rack and Cargo Carrier Recommendation for 2015 Lexus RX 350
    There really isn't a great way to accomplish what you are trying to do. The dual hitch receivers like the part # D-192 cut the capacity of the hitch they are installed in by 50 percent and add quite a bit of leverage to the hitch. I really wouldn't recommend going this route. A better choice would be the # HR1400Z-85 which has a bike rack and a cargo carrier behind it. As long as you have a 2 inch hitch installed on your 2015 Lexus RX 350 like the part # C13143 you would be good.

    Thank you for all of the info and the pictures! I believe from everything you are saying that you are trying to use the Roadmaster Falcon All Terrain Tow Bar # RM-522 and the Swagman G10 S64682 with your Roadmaster Dual Hitch Receiver Adapter # RM-077-2. You may be able to use the Curt Dual 2" Receiver Tube Adapter # D-192 instead but it only has 3-1/4" of clearance between the top of the bottom receiver tube and the bottom of the top receiver tube so I'm not sure if you will have enough...

    The Curt Multipurpose Ball Mount # D210 is not offered with different amounts of drop from the ball platform to the receiver opening. It comes only in this particular size which, importantly, does not reduce your hitch's capacity the way most other adapters do. We do offer Curt's Dual Receiver Tube Adapter # D-192 which provides two 2-inch receiver opening, a top one for use with accessories like bike and cargo carriers and a bottom one that accepts either a tow bar shank or a 2-inch ball...

    It is possible to carry both the Darby Extend-A-Truck Kayak Carrier part # DTA944-968-924 and certain bike racks on the rear mounted hitch receiver however, you will need to have a bike rack with a shank long enough to clear the Darby Carrier.

If there is enough clearance to account for this, then you can use our Curt Dual 2" Receiver Tube Adapter part # D-192 to carry both the Darby Kayak Carrier...

  • What 4-Bike Bike Rack do You Recommend for My 2021 Hyundai Palisade?
    I have a great solution for you. I confirmed with Curt that they do not have a tongue weight rating for the Curt High-Low Adapter for Tow Bars - 2" Hitches - 4" Rise/Drop - 8" Long # C59KR because this adapter is recommended to use for flat-towing applications only. With that being said, the Curt High-Low Adapter # C59KR only has a tested gross towing weight capacity of 7,500 pounds. However, if you want a great adapter alternative that has been tested for its tongue weight capacity, I...

  • Recommended Adapter for Ground Clearance of Bike Rack
    The Curt Dual 2" Receiver Tube Adapter, 8" Extension # D-192 will work well to give you the extra height you desire but using any adapter will reduce your hitch tongue weight by 50%. This won't be an issue with a Curt Class III hitch is you just use your Ridgeback # Y02457. A similar option for more height is the Malone 2" Dual Purpose Hitch Receiver # MPG544 but it will also extend the length of the hitch 2-1/2 more inches than the # D-192. This will probably result in the adapter...

    Based on your information, a dual hitch extender like the Curt Adapter, Item # D-192, will not work for you or with a weight distribution system. About the only way you can have both a bike rack and a weight distribution system is to look at something like the Gen-Y Adjustable 2-Ball Mount with Stacked Receivers, Item # 325-GH-315. With this ball mount, you will be able to tow your trailer with weight distribution and carry a 2 inch hitch mounted bike rack. For example, the Kuat Beta...

  • Can Dual Hitch Adapter Be Used with Weight Distribution System
    Makers of weight distribution systems generally do not recommend using any sort of hitch adapter/extender with their systems. The reason is that such adapters/extenders like Malone # MPG544 and Curt # D-192 reduce your trailer hitch's tongue weight rating, and by a full 50-percent. The loss of hitch TW capacity derives from the change to the overall geometry of the set-up; the whole WD head and shank will be further from the hitch and this applies extra leverage on the hitch tube, reducing...

    I do have an option for you but you cannot use multiple hitch adapters together like the dual hitch adapter part # D-192 and the hitch extender part # C45791 for example. This would create too weak of a connection point and would limit your towing capacity to almost nothing. If you need to tow a trailer and haul a bike rack at the same time a much better option for you would be with the Curt Multipurpose Ball Mount part # D210 or the Jack-It 2 Bike Rack part # LC429756.

    In order to be able to carry bikes between your towed vehicle and the RV you will first need a dual receiver for your trailer hitch.

  • Can Curt Dual Hitch Adapter part # D-192 be Used to Carry Bike Rack and Flat Tow a Vehicle
    The part # D-192 is designed for what you are looking to do. It will allow you to carry a bike rack and flat tow a vehicle. There are some capacities you need to keep in mind though. The # D-192 has a 3,500 lb towing capacity so you need to make sure your vehicle weighs less than that. The # D-192 also cuts the capacity of your trailer hitch by 50 percent so you need to keep that in mind as well.
