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

Average Customer Rating:  4.8 out of 5 stars   (115 Customer Reviews)

Extend your trailer hitch receiver opening and get an extra receiver with the same piece. This dual hitch extension gives you (2) 2" receivers so you can tow a trailer and use an accessory at the same time. Powder coated steel resists rust.


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.

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.

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.


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


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.


Excellent products


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.

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.


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.


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.


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.


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.


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.

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.


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!


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.


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.


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


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.


I turn it over to lower the mobility scooter carrier down low enough to be able to run the scooter on and off of the ramp that is attached. Would like to sent a picture but have no way of doing so. I am very pleased with the product and quality of it. I have a 2017 Ford Explorer with a factory hitch, very high.


Hitch receiver very well built solid steel shank so the anti rattle hitch pin could not be used on it. I put it on the back of my motor home so I can use the bike rack and tow my Jeep at the same time. Drlrvery time through UPS was outstanding as we move quite often because we full time RV.

  • The Best Cargo Carrier To Use While Towing A Vehicle
    The Curt Dual 2" Receiver Tube Adapter part # D-192 is a great option. Please note: Your tongue weight will be decreased by 50% while using any type of adapter. You will also want to consider the Anti-Rattle Trailer Hitch Receiver Lock part # 63232 to secure the adapter to your hitch receiver as this has both locking and anti-rattler features.

  • How to Use a Cargo Carrier and Bike Rack Together
    Depending on your rack and carrier, they maybe able to be used at the same time, but more than likely, one will interfere with the other. Keep in mind the shape of your bike rack may interfere with loading cargo on your carrier and the carrier may be in the way of the bikes hanging down. If the cargo carrier has sides or rails that are tall, they may prevent the bike rack from being installed. Additionally this adapter/extension has a tongue weight rating of 350 pounds. This means that...

  • Dual Hitch Recommendation for Carrying a Thule Apex Bike Rack and Towing a Small Trailer
    The Curt Dual Reciever Hitch # D-192 that you referenced should work well for you as long as the hitch on your vehicle has the capacity for the tongue weight of your trailer plus the weight of your Thule Apex Swing Away Carrier # TH9027 and bikes. You should note that when you use a hitch extender such as the # D-192 you cut the capacity of the hitch in half. So as long as you confirm that you have enough capacity you should have no problem using this setup. I attached an FAQ article...

  • Way to Drive Up Steep Driveway and Prevent Wheelchair Carrier from Dragging
    Hitch extenders and similar adapters cut the capacity of the hitch they are installed on in half so I can't recommend any product (if there was one available), that would allow you more clearance so that your wheel chair carrier would clear the driveway angle better. The best solution I can provide for you would be to approach your driveway at an angle so that the carrier won't tilt back as far as you make the transition up the driveway.

  • Can the Curt Dual 2" Receiver Tube Adapter, 8" Extension # D-192 be Used to Tow a Boat Trailer
    The lower hitch opening of the Curt Dual 2" Receiver Tube Adapter, 8" Extension # D-192 that you referenced can be used for flat towing and towing trailers like you are interested in doing. You should note that this has a capacity of 350 lbs TW/3,500 lbs GTW and will reduce the capacities of the hitch it is used on by 50 percent.

  • Could I Use a Curt Dual Reciever # D-192 to Flat Tow a 2005 Pontiac Vibe and Carry a Bike Rack
    I did a little research and found that based on various options your 2005 Pontiac Vibe will weigh around 2,700 lbs, which is much less than the 3,500 lb limit of this Curt Dual Reciever # D-192. Also, you are correct, when using a tow bar there will be a minimal amount of tongue weight on the hitch. And, based on the fact that you will only have 100 lbs in bikes and bike rack on the top receiver you should be good in that regard.

  • Bike Rack Availability for an RV Towing a Jetta on a Tow Dolly
    I have a solution for you, but it won't include your Thule T2 bike rack unfortunately. The T2 isn't rated for use behind an RV so it can't be used with the hitch adapter # D-192 on your RV. There are RV rated bike racks available that could work. I attached a link to all of them for you to check out. You will want to pick out the one that would work the best on your application. There are hitch mounted racks, ladder mounted racks, and bumper mounted racks.

  • Can the Curt Dual Ball Mount # D-192 Be Used in the Drop Position
    If you wanted to carry a bike rack in the lower position with the # D-192 in the drop position (the second hitch opening facing down), you could. However, if you are needing a way to lower the ball mount platform of your hitch ball so that you can tow a trailer level you would be better off going with a ball mount with more drop. Check out the FAQ I attached on picking out the correct rise/drop ball mount to the right.

  • Adapter Recommendation for Lowering a Yakima Doubledown Bike Rack
    I believe I have a solution that would allow you to lower your Yakima DoubleDown, but the Roadmaster Hi/Low adapters are not rated for any use besides flat towing. Check out the Curt Hitch Adapter # D-192. You could flip this product so that the additional hitch opening sits lower. You should note that any time you use a hitch extender or adapter you cut the hitch capacity in half. So you will need to determine if half of your hitch capacity will be enough for the weight of your bikes...

  • Towing Capacity Using Curt Dual 2 Inch Receiver Tube Adapter # D-192
    A dual hitch extender like the Curt Dual 2" Receiver Tube Adapter, 8" Extension # D-192 will not effect your towing capacity, but will effect your tongue weight capacity by 50%. So depending on the tongue weight of your trailer, it may or may not allow you to use your trailer and an additional accessory as the combined tongue weight rating is going to be a limit of 350 lbs.

  • Solution for Raising Curt Hitch Mounted Cargo Carrier
    The best solution to raise your Curt hitch-mounted cargo carrier further above the ground is with an adapter like the Curt # D-192. This provides you with a top 2 inch receiver that sits 3-1/4 inches above the hitch on your vehicle. As you referenced in your question, using an adapter like this will reduce the tongue weight capacity of your trailer hitch by 50 percent. For example if your hitch has a tongue weight capacity of 300 pounds this will be reduced to 150 pounds when using the...

  • What Does Reduction of Hitch Capacity With Receiver Adapter Mean?
    When using the Curt Receiver Tube Adapter # D-192, what a 50 percent reduction means is that the hitch's towing capacity and tongue weight - both - will have their capacities reduced by 50 percent. As a simple example, if your hitch had a towing capacity of 5,000 lbs and tongue weight capacity of 500 lbs then using adapter # D-192 will reduce the towing capacity to 2,500 lbs and tongue weight capacity to 250 lbs.

  • Dual Hitch Adapter to Fit 2 inch Hitch with Zero Drop on Lower Hitch Opening
    The closest match we have is the part # D-192 but this only has a 3,500 lb capacity. If you could get by with a 3,500 lb capacity this would be the adapter to go with.

  • Does Hitch Adapter with 2 Hitch Openings Cut the Capacity of the Hitch by 50 Percent
    The setup you sent in a picture of is going to have a hitch tongue weight setup reduced by 50 percent. It's the added length added to the hitch and the increased movement that puts leverage and stress on the hitch which is why the capacity is diminished.

  • Is Tongue Weight Capacity Reduced When Using Curt Dual 2-Inch Receiver Tube Adapter D-192
    Yes, use of the Curt Dual 2-Inch Receiver Tube Adapter # D-192 does reduce your hitch's tongue weight (TW) capacity by half. Towing capacity is not reduced. The 2016 Fit curb weight is between 2513 and 2642-lbs so if your tow dolly's weight does not put you over 3500-lbs you're okay. Since the tow dolly carries the weight of the car's front end, there is really very little actual TW from the dolly put on the adapter or hitch. The weight of the bike rack and the loaded bikes does count...

  • Tongue Weight Capacity of Dual Hitch Receiver Adapters
    The weight capacity of a dual hitch adapter like the Curt # D-192 is a total combined for the entire adapter. The Curt adapter has a total tongue weight capacity of 350 pounds. So you won't be able to carry 300 pounds on just the top receiver unless the bottom one has very little weight on it. In addition you will need to make sure that the hitch the adapter is installed in, and the vehicle with the hitch are both rated for the capacities you're tying to carry.

  • 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. So basically you need to have a hitch on your vehicle with twice the capacity needed for the...

  • Dimensions for Curt Dual 2 Inch Receiver Tube Adapter D-192
    I went out to the warehouse to take a look at the Curt Dual 2 Inch Receiver Tube Adapter # D-192 referenced in your question. I measured a distance of right at 7 inches from the back of the top receiver to the back of the bottom shank. There is a distance of 5 inches from the center of the hitch pin hole to the back end of the top receiver. I have attached an image with these dimensions labeled that you can also check out.

  • Could Curt Hitch Adapter D-192 be Used in Drop Position for Carrying Bike Rack
    Using a hitch extender like the Curt Dual Adapter part # D-192 does cut the capacity of the hitch it is installed in by 50 percent, so if your hitch has a capacity that is currently double the capacity needed for your bikes and bike rack this would be a viable option. This also can be used in the drop position if needed as well.

  • Is There a Dual Hitch Receiver Adapter for 1-1/4 Inch Class I and Class II Trailer Hitches
    There is not a dual hitch receiver for the 1-1/4 inch receivers as they are not able to handle the torque due to the tongue weight location. The tongue weight of the hitch is reduced by 50% when using an adapter, so it really wouldn't be worth using for most applications.
