Curt Dual Hitch Extender for 2" Trailer Hitches - 8" Extension - D-192

Average Customer Rating:  4.8 out of 5 stars   (111 Customer Reviews)

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
Roadmaster Quiet Hitch for 2" Trailer Hitches
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.

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.


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


This has worked out great because I have a 16 foot canoe that I put on my roof rack on my Jeep and the back of it on my yak bone and there's enough space that my yak bone does not touch any park of the trailer.


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 this hitch riser to use with a bike rack and tow bar for later in the year. Looks to be very well built. I will add comments once we start using.


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.


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


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.


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.

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!


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.

quality is oustanding


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.


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!


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


Does the job. Allows for a bike rack and a boat towed off the same hitch.


I've used this a couple of times before the end camping season last year. I really need to now get a drop extension for the bottom adapter so that the camper's tongue doesn't hit the bikes. I think it will work out just fine.


Have a RAV 2017 and with the regular hitch set up I kept bottoming on when pulling in driveways. NOT ANY MORE this worked great even on the biggest dippy entrance at SAMS. Salespersons should recommend this for anyone with a RAV who is buying a hitch.


Awesome hitch can hardly why to use it now that I have it

It is working out great
Van - 08/20/2021


Great service! I received the adapter in short order and in great condition. I have a need to tow a car and a double trike carrier with my RV. Before I purchased this adapter I had a choice of towing one or the other. Now I can take both!


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.


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.


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.
