Roadmaster Dual Hitch Receiver Adapter with 2" or 6" Drop/Rise - RM-077-6

Average Customer Rating:  4.8 out of 5 stars   (148 Customer Reviews)

Add a bike carrier or cargo carrier with the dual hitch receiver.

by:

Worked out great for my family bike adventure. Traveled with that setup over 1000 miles and it was easy drive. I had cargo carrier on the bottom and bike rack on top, and with that setup and 4 people on board still plenty of ground clearance 11". Dual hitch is a solid piece of steel that can carry a lot of lbs. Just don't overload max. tong weight, need some room for safety!



by:

This adapter design was exactly what I was looking for. I often carry 4 or more bikes with my Sylvan GO. The pictures show how I configured my setup. Its perfect!!! And yes, I have to be a little careful on really tight turns but its never been an issue. Thank you George and the etrailer team.



by:

Great hitch. Exactly what it says in the description. Works perfect for my Blue ox tow bar and my 1UP bike rack.



by:

This seems sturdy and fits, but it is a slightly loose fitting. A better design would enable you to tighten the fit.

If you are having issues with it sitting tight, you could always use an anti-rattle hitch lock, like part # RM-061 to reduce the loose fit.



by:

Exactly what I needed to not only tow our Jeep, but also to put our Hollywood bike rack on. Great quality!



by:

This hitch adapter is just what I needed to carry bikes and flat tow my car. Etrailer is very helpful as carry what I need.



by:

Built stout, fit perfectly. Suggest buying a locking hitch pin!



by:

I use this for towing my TOAD and flipped up using the upper one for my E-bike rack. After 1 year, this dual receiver has worked flawlessly and is very strong. I would recommend it to anyone who needs something along this line. Lastly using a hitch clamp / anti wobble device will take any play out the receiver.



by:

We bought this hitch along with a bike rack. After a year of use we are still travelling across North America. Awesome product! Easy and totally easy to use.

Delivery was fast and efficient.



by:

Does it's job well. Holds the bike rack for the ebikes and allows us to tow our Jeep behind the RV.



by:

As Expected. 2" drop aligned car tow bar. Hope to use 5" rise for bike rack in future.



by:

Just what I needed for my tow and bikes.
Thank you.



by:

Works as designed, well built,



by:

Really quick delivery. Hitch is very heavy duty. Just what I wanted.



by:

It looks to be exactly what I need to raise my carrier up higher



by:

I wish the pin bore was not so far back. The instructions say a second hole can't be drilled to allow it to set closer to the vehicle. Will make it work as is I guess.



by:

Solid product!! Fits perfectly and looks great :-D Puts my bike rack a nice distance over the tow arm. Nice to find one that is rated to 10,000 lbs even thought I'm towing 5,000.



by:

Very well built, great finish too.



by:

This adapter is solid. Very well made.



by:

Great addition to my car.



by:

Great solid quality. Excellent costumer service!



by:

heavy duty. fast shipping



by:

Another Roadmaster quality product, amazed as how it has resisted signs of rust or corrosion from being exposed to the elements. Part looks as good as new.



by:

Fast delivery of part and works very nice. Still need to see how it travels but stationary it looks great!



by:

This was the perfect solution for our problem. We needed to add a bike rack to our hitch that we already used for towing.

  • Roadmaster Dual Hitch Adapter with 6 inch Drop for Flat Towing Vehicle and Carrying Bike Rack
    Yes the Roadmaster dual hitch adapter part # RM-077-6 that has a 6 inch drop hitch opening as well as a higher one that you could use for your bike rack would work great for you. This adapter was designed for basically your exact situation where the lower hitch is used for the tow bar and the upper one for an accessory like a bike rack.

  • Can Recumbent Bike Rack be Used with Roadmaster Dual Hitch Receiver Adapter
    The tongue weight capacity of the # RM-077-6 is 400 lbs so as long as your rack and bikes weigh less than that considering the tongue weight of your tow dolly as well you'd be fine.

  • Can Roadmaster Dual Hitch Receiver Adapter # RM-077-6 be Used with Tow Dolly
    At one point Roadmaster would only recommend the use of the Roadmaster Dual Hitch Receiver Adapter # RM-077-6 with flat towing setups but they recently changed that stance and now allow the hitch adapter to be used with a tow dolly like they told you.

  • Hitch Extender with 4 to 6 inches of Rise to Carry a Bike Rack or Cargo Carrier
    It sounds like you're looking for a hitch adapter that gives you 4 to 6 inches of rise to carry a bike rack or cargo carrier. We don't have a standard adapter with a rise but we do carry dual hitch adapter that have two receivers where one is used in the rise position. You don't have to use the other receiver opening if you don't need it. I recommend the Roadmaster, part # RM-077-6, because it has a 6 inch rise and is rated for up to 400 pounds of tongue weight. Since it has its own...

  • Weight Capacity of the Roadmaster Dual Hitch Receiver Adapter
    The Roadmaster Dual Hitch Receiver Adapter, 2" or 6" Drop/Rise # RM-077-6 will be able to hold your spare tire as long as you are not exceeding the tongue weight capacity of the adapter or your trailer hitch. The Roadmaster adapter has a maximum tongue weight of 400 lbs. So, as long as you are not over 400 lbs of tongue weight the adapter won't have any problems.

  • Dual Hitch Adapter Solution for Needing 6 inch Rise/Drop
    I have a solution for you but we can't recommend using two hitch adapters at the same time due to how much added leverage and movement would be added. Instead your best option would be Roadmaster dual hitch adapter like the part # RM-077-6 which gives you ability to have 6 inch rise or drop for one hitch opening and a 2 inch rise/drop for the other opening.

  • Which Dual Hitch Adapter Has the Highest Tongue Weight Capacity
    The dual hitch adapter we carry with the highest tongue weight capacity is the Roadmaster Dual Hitch Receiver Adapter part # RM-077-6 for 6" rise or part # RM-077-8 for 8" rise. They both have a 400 lb tongue weight capacity. Please note that this adapter is designed for flat towing only. If you can give me a better idea of what you are using the adapter for we may have alternative options if the above will not work.

  • Dual Hitch with 6 Inches of Drop
    Sure is. You need part # RM-077-6 which has a rise or drop of 6 inches depending which way you use it. It's exactly like part # RM-077-8 except for the amount or rise/drop.

  • Roadmaster Hitch Adapter for Flat towing a 2018 Jeep Rubicon and Two E-Bikes
    I recommend the Roadmaster Dual Hitch Receiver Adapter, 10" Drop/Rise item # RM-077-10. This adapter was designed for this type of set up. Your Jeep Rubicon and Swagman E bike rack weigh well below the 10,000 lbs maximum capacity of this hitch. I have attached a review video as well as a picture that show this rack being utilized in the same way.

  • Which Roadmaster Dual Hitch Adapter For Carrying Bike Rack While Flat Towing
    Since the receiver height and the base plate height of the vehicle is the same, you won't need to worry about keeping the tow bar level. If your bike rack has an angled shank with a couple inches of rise to it, you could use the # RM-077-6. If the bike rack has a straight shank, you'll want a dual-hitch adapter with a larger rise such as # RM-077-8 for an 8-inch or # RM-077-10 for a 10-inch rise to move the bike rack up and out of the way. The adapters have a tongue weight capacity...

  • How To Carry Bikes and Use a Tow Bar On the Back Of An RV
    In order to carry bikes on the back of an RV and still use a tow bar you'll need to look into a dual high, high-low adapter like the Roadmaster Dual Hitch Receiver Adapter for Tow Bars part # RM-077-2. This adapter is also offered in a few other rises/drops like part # RM-077-4 and part # RM-077-6.

  • Recommended Dual Hitch Adapter for Newmar Baystar Towing 2013 Jeep Wrangler Unlimited
    Thank you for providing those helpful measurements. With the 8" difference I would go ahead and choose the Roadmaster Dual Hitch Receiver Adapter, 2 " or 8" Drop/Rise # RM-077-8 over the # RM-077-6. Loading it won't make much of a difference on the height. Also, the flat towed vehicle adds no tongue weight so really there should be no sag at all. Even if you did somehow drop 2" after loading your motorhome you would still be in the safe zone, which is +/- 3" from level. If you want to...

  • Is it Possible to Carry a Scooter Carrier and Flat Tow a Vehicle
    A scooter carrier is a bit heavy but we do have dual hitch adapters like the Roadmaster part # RM-077-6 which have a tongue weight capacity of 400 lbs and is designed for flat towing a vehicle and carrying an accessory above it.

  • Recommended Dual Hitch Adapter and Cargo Carrier for Flat Towing/Carrying Bike Rack and Cargo Carrie
    You can use a Dual Hitch Adapter like # RM-077-2 so you can simultaneously carry a cargo carrier/bike rack and flat tow. There are a couple things to keep in mind, though... Using an adapter will reduce the tongue weight capacity of the hitch by half. Therefore, if the hitch has a tongue weight capacity of 350 lbs, using the adapter will reduce that capacity to 175 lbs. That's not a big deal for the flat towed vehicle, because flat towed vehicles are a rolling load that don't exert any...

  • Hitch Adapter Added To Dual Hitch For More Clearance
    It Is not at all recommended to use two adapters with eachother, so your best option would be to use the Roadmaster Dual Hitch Receiver Adapter # RM-077-6 which features a 6" rise or drop which should give you plenty more clearance, we do also offer the Roadmaster Dual Hitch Receiver Adapter # RM-077-8 which will give you an 8" rise or drop for even more clearance; and the last height we offer is the Roadmaster Dual Hitch Receiver Adapter # RM-077-10 which offers a 10" rise or drop for...

    The best way to flat tow your Fiat 500 or Mini Cooper and also transport your two e-bikes is with a Roadmaster Dual Hitch Receiver Adapter like # RM-077-6. This adapter is specifically designed for this application, providing you with a 2 inch receiver on the bottom for attaching a tow bar and an additional 2 inch receiver on top to attach a hitch-mounted accessory like a bike rack.

  • Hitch Receiver Adapter With a 6" Rise For Tow Bars To Sit Level
    Yes, the Roadmaster Dual Hitch Receiver Adapter # RM-077-6 can be flipped to raise the receiver 6" and allow your tow bar to be level. You would not be able to use the lower receiver tube with your tow bar on top. I recommend the Roadmaster High-Low Adapter # RM-048-6 for raising your tow bars. This will ensure that the additional receiver does not hang to low as it may catch on road debris or contact speed bumps depending on the height of your vehicle receiver. The Roadmaster Quiet...

    There is not a maximum length ball mount or hitch extension that can be used in a flat-towing setup. However, the further out you go, the less tongue weight the ball mount or extension will be able to carry which is not really an issue for a flat-towing setup but is something you need to keep in mind.
