Receiver: 2" x 2"
Tongue weight: 400 lbs
Gross towing weight: 10,000 lbs
Length:
- 11-1/4" From center of hitch pin hole to center of hitch pin hole
- 4-1/2" From center of hitch pin hole to angled brace

Note: This adapter is designed to flat tow a vehicle only. Do not use to tow a trailer. When using with a hitch-mounted accessory, such as a bike rack or cargo carrier, the tongue weight of your hitch will be reduced by at least 50 percent.

Most tow systems require some sort of hitch accessory to either raise or lower the tow bar to an appropriate level. The "Safe Zone" for a motor-home-mounted tow bar ranges from 3" above level to 3" below. Car-mounted models must be absolutely level. This high-low adapter can provide you with the necessary drop or desired rise to achieve a level tow bar setup.

This drop down hitch by Roadmaster is extremely well made. Welds are strong and steel is heavy gauge. Has a nice shiny black finish. Very satisfied.

Very strong hitch adapter. If you need to extend your hitch up or down I recommend this one.

Very reliable for is intended purpose. Should definitely use hitch locks while towing. This adapter will reduce the maximum weight that can be towed.

etrailer customized the RM-048-10 by lengthening the shaft so that it would fit through the bumper of our Class C RV and be strong enough to support the Stowaway 2 Cargo Carrier. It works beautifully! During travel there is some left to right wiggle that occurs with the carrier. We solved this problem with ratchet straps to secure both sides of the carrier. The hitch is stout and strong, and does the job! Of course we strengthened it with the clamps, so the hitch is solid and unmovable. With the custom hitch, the Stowaway 2 carrier is lifted enough so that it doesn't bottom out when traveling up or down steep hills. etrailer staff are very easy to work with, along with the brilliant engineers who communicated well with the exact details of the design to assure the build worked safely. It is an excellent hitch; worth the value. We're on the road again with all of our lawn chairs/tables, etc. in the cargo carrier out of the elements, instead of inside the RV. Great work, etrailer! Thank you! S&S

This was the perfect height to level my tow bar to my lifted jeep. I recommend using a good quality clamp on the upper and lower receiver to stabilize the hitch assembly.

Mounted on Jeep Grand Cherokee to lower hitch for attachment of wheelchair/scooter carrier. Does the job, and also extends the carrier further rearward, which provides sufficient clearance for the rear hatch to clear the scooter when loaded.

It's a big drop, 10 inches. I needed to get a 35 gal. tank low enough to the ground to drain waste water from my camper and take it to the dump station without always hooking back up to the camper. The waste tank sets on the aluminum platform and is easily transported to where it needs to go. The high-low adapter is rated at 10,000 pounds and more than I need for this application but it's going to be used for other things too.

by: Farmer John 09/08/2022

No good for a rise. The angle caused too much leverage and the pin hole does not leave enough depth for a deep shank. No way this thing is doing 400 lb TW without bending up your hitch/frame. Looked shakey at 200lb. I got the Blue Ox High-Low Adapter for Tow Bars - 2" Hitches - 7" Rise/Drop - 12" Long and use that one instead.

The highlow adapter is primarily designed for use when flat towing a vehicle, where theres no tongue weight applied to it. If used for a hitch mounted accessory, the tongue weight capacity of the hitch and the adapter itself is reduced by 50. The adapter is NOT meant for towing a trailer.

by: Jimmyj 10/17/2019

Called to ask a question about a trailer hitch riser I wanted. Got my answer and customer service guy placed my order while I was on phone. Part came quickly and was exactly what I needed. etrailer is a great on line retailer and I recommend them highly.

I bought this receiver for use with my bike rack. I have a frame mounted receiver on the back of my travel trailer. Before I used the receiver, the tires from my bicycles would strike the ground going over uneven ground, such as driveways. By flipping the receiver upside down, the 10 inch rise gives me tremendous clearance to prevent the bicycle tires from striking the ground. I now use the receiver for the rear receiver on my 3500 GMC. I have used the receiver over one dozen times and have not had any issues.
The only down side, is the weight of the receiver; but for the quality and strength of the receiver, I can happily live with the extra weight.

I needed this much drop to tow my low Ford Fiesta behind my Winnebago Sightseer. Didn't register how high the hitch was on the Winnebago when I bought it. This adapter fit the bill perfectly, got great service from the folks at etrailer, and have had no problems with the adapter.
You can't go wrong with etrailer.

What do I Need to flat Tow a 2011 to 2013 Jeep Grand Cherokee Behind a Motorhome
To flat tow a 2011 to 2013 Jeep Grand Cherokee there are 5 major components needed: base plates, tow bar, safety cables, lighting, and supplemental braking. The base plates are what attach to the front of the Jeep and provide a safe and proper attachment point for the tow bar. For the 2011 to 2013 Grand Cherokee I recommend Roadmaster EZ5 base plates # RM-521440-5. These base plates feature removable arms that, when removed, makes the base plates almost invisible.

Tow Bar With Cable Management for 2023 Newmar Kountry Star
Hi Edward, what exactly do you mean by a hitch riser? Do you mean a high-low adapter like # RM-048-10? Can you email me a picture? The Roadmaster Falcon 3HD Tow Bar # RM27NQ is a great option with channels for cables. It will connect to any 2" receiver and then to your base plate so something like a high-low adapter doesn't require anything special on the tow bar to work properly.

Troubleshooting Flat Tires When Towing Mini Cooper With 2011 Holiday Rambler
First, before flat towing your 2011 Mini Cooper, be sure the tires are filled to the recommended psi and in good condition. More importantly, be certain your steering column is not locked; if your tires are unable to turn they would wear out quickly. If you think your safety cables may be an issue, and yours are shorter than 7', an option would be the Blue Ox Blue Ox 7' Safety Cables # BX88197. Another thing you could do is add an anti-rattle device such as the Blue Ox Hitch Receiver Immobilizer...

Looking For High-Low Adapter For E-Bike Rack With 8"-12" Of Drop
Hey Dave, welcome back. We do have high-low adapters with that amount of drop. Take a look at the following: - Roadmaster High-Low Adapter - 2" Hitches - 10-1/4" Rise/Drop - 10K GTW, 400 lbs TW # RM-048-10 The main thing to keep in mind when using an adapter like this is your total tongue weight. Using a high-low adapter or hitch extension effectively reduces your hitches carrying capacity by half. So, for example, if the hitch on your Sequoia is rated for say 600 lbs of tongue weight,...

Recommended High/Low Adapter w/a 10" Rise and a 10,000 lbs Capacity
Thanks for the information Steve! That is quite the difference in height. I recommend the Roadmaster High-Low Adapter item # RM-048-10. It fits a 2" hitch receiver, will give you a 10-1/4" rise, and most importantly has a 10,000 lbs capacity. It looks like the 2025 Bronco's weigh anywhere from 5,100 lbs - 6,700 lbs if you have the Raptor once you get them loaded up. What kind of motorhome do you have and does it have a 2" hitch? You can add this information, along with any other questions...

Does 2025 Winnebago Hitch Drop Limitation Apply To High-Low Adapter for 2016 Equinox
Hey Michael! That restriction would be for a ball mount towing a trailer with tongue weight. It is different when you're flat towing your 2016 Chevrolet Equinox. You want to be within 3" of level so you can use the Roadmaster High-Low Adapter - 2" Hitches - 10-1/4" Rise/Drop # RM-048-10 with that setup. Where are you headed first once you get the Equinox all set up?

These range from a 2" rise/drop # RM-072-2 all the way to a 10-1/4" rise/drop # RM-048-10. If you're looking for an option with about a 7" drop like what the Malone # RM-048-10...

Parts Needed To Flat Tow a 2024 Ford Escape
Since the 2024 Ford Escape is unchanged from the 2023 I see no reason you would not be able to use the Roadmaster Base Plate # RM77GR on the Hybrid trims. I recommend using the Roadmaster Nighthawk Tow Bar # RM-676 and the Accessory Kit # RM-9284-2 to connect your Escape. You will also need a Charge Line # RM-156-25 to prevent your battery from being drained down while towing. I do recommend using either the Air Force One # DM26VR if your motor home has actuate brakes or Stay-IN-Play...

Highest Amount of Rise for a High/Low Hitch Adapter for Use with Tow Bar
When using a tow bar to pull your modified 2016 Jeep Wrangler Unlimited you will need a high/low adapter to reduce the height difference between it and the RV. The greatest amount of rise available comes from the two items shown on the linked page, Roadmaster # RM-048-10 and Blue Ox # BX88132. There is no adapter with 15-inches of rise. Generally tow bar makers recommend no more than 3-inches above or below level for either end of the tow bar, so you may need to re-position your D-rings...

Solution to Allow a Cargo Carrier be Carried Higher than Stock Hitch Height
Because the high/low adapters like the part # RM-048-10 that you referenced are only designed for flat-towing purposes I cannot recommend you use one with your cargo carrier. The best recommendation I could make for you would be to use a Curt Multipurpose Ball Mount # D210. This will give you about 4-1/2 inches of additional rise for your cargo carrier.

Carrying Bikes at the Back of an RV While Towing a Car on a Tow Dolly at the Same Time
There are a couple of hurdles to overcome in order to be able to carry bikes while using a tow dolly at the same time. First there is the drop issue. The most amount of drop from an adapter that we have is 10-1/4 inches, # RM-048-10, which will still work even if it doesn't quite get down to 12 inches. There aren't any dual receivers that you can use that will also have enough drop and work with a tow dolly. So what I propose is to use the above 10-1/4 drop adapter with a different kind...

Recommended Flat Towing Parts for a 2026 GMC Sierra 1500
You sure can Joe, and congrats on the new truck! You will need a high/low adapter that's a bit taller though since your Sierra is lifted. Something like the 8" item # RM-048-8 or the 10-1/4" item # RM-048-10 depending on how low to the ground your motorhome's hitch is.

Can Two High-Low Adapter be Used to Achieve Needed Rise or Drop
To achieve a 10 inch drop to keep your tow bar within the "Safe Zone" (3 inches above or below level) I definitely recommend going with a single high-low adapter that features the full 10 inch drop. The potential issue with using 2 adapters like you mentioned is that it's going to cause an awful lot of movement at the connection point which may lead to failure down the line. With a flat towing setup using 2 adapters like this isn't as much of a concern compared to with a hitch mounted...

How Far Off Level Can a Tow Bar Be When Flat Towing a Vehicle Behind an RV
For most tow bars the "safe zone" between the RV and the toad is 3 inches off level. The height is measured from the ground to the center of the receiver opening and to the center of the base plate. If you find that your set up is outside of the safe zone then there are high/low adapters you can use to compensate for the height difference. I have included a link to our help article explaining the adapters and safe zone as well as a link to our selection of high/low adapters.

Hitch High/Low Adapter for Better Ground Clearance When Using Cargo Carrier
Roadmaster High-Low Adapter # RM-048-10 for 2-inch hitches will give your hitch-mount cargo carrier 10-1/4-inches of height gain for better ground clearance. It will also reduce your hitch capacity by 50-percent, as do all such adapters/extenders. This loss of hitch capacity results from the change in geometry, which moves the carrier's weight load further away from the hitch itself. You'll need to make sure the combined weight of the carrier and its loaded cargo does not exceed half of...
