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.

Video Transcript for Roadmaster High-Low Adapter for Tow Bars Review

Today we're gonna be taking a look at the Roadmaster High-Low Adapter for tow bars, part number: RM-048-2. Now, our high-low adapter's not only for tow bars, and it's not only to be used in the lowered position. We can actually flip it around, put it in the rise position, and we can actually mount any kind of accessory -- such as a bike rack or cargo carrier -- and then now we have more adequate ground clearance. Now as you can see, this is gonna give us adequate clearance for our bike rack, and we're not gonna have to worry about bottoming out. There is one thing I would like to mention, when you are using the high-low adapter in conjunction with a bike rack or a cargo carrier, you need to keep in mind, the tongue weight is gonna be reduced by at least 50%. Our high-low adapter does feature a solid shank, so it's gonna be extra strong and durable. Our high-low adapter is designed to work with 2" hitches only, and the pin and clip is not included, but you can pick one up on our website using part number: PC3.

The overall length of our adapter is gonna be 14-5/8". From the center of the hitch pin hole to the center of the other hitch pin hole, it's gonna be right about 10-1/8". Our high-low adapter is gonna feature a 400lb tongue weight and a 10,000lb gross trailer weight. Now I want to mention, you always want to double check not only your motor home and the hitch that it's attached to, but also how much you're gonna be carrying. If you ever went to flat-tow your car with your RV, you had a tow bar involved. Every tow bar's a little different, but the manufacturer does recommend that you try to get it level as possible between where it connects to your vehicle and where it connects to the RV.

Now, in our application, the center of our hitch pin hole is right about 21", and the center of our base plate attachment point is right about 18". Now that's the maximum allowed clearance that we're allowed in difference between our tow bar and our base plate connection, but that's where our adapter comes into play. Since our motor home is 3" higher than our connection point on our tow bar, we're gonna put it in the lower position, that way it's almost level. Now we can slide it in, line up the pin hole in the receiver, and then we can put in our 5/8 pin and clip. Now we can safely attach our tow bar and not have to worry about anything binding up because of the extreme angles. Now that we have our adapter installed, let's go and check our measurements again.

Now the center of the hitch pin hole under my adapter is just over 18", my tow bar is right at 18", so it's almost perfectly level. Now we can put in our tow bar into the high-low adapter so it'll be the right angle to tow our vehicle. Now we can put in our pin and clip. And we're ready to hit the road. And that'll finish up our look at the Roadmaster High-Low Adapter for tow bars, part number: RM-048-2.

Average Customer Rating:  4.9 out of 5 stars   (39 Customer Reviews)

Make up for the height difference between your RV and towed vehicle with this hitch adapter. Provides either a 2" drop or a 2" rise. Solid shank provides strength and durability.


I run a motorhome during the summer. I changed towed vehicles from a Truck to a SUV. This Hi/Lo receiver is what I required to ensure a straight tow. I went with the heavier 10K rating. Etrailer may not be the cheapest on the net, however very reliable. The picture shows the finish tow setup. The piece above everything is a motorcycle lift.


Works well on my 2014 Wrangler Unlimited. Yakima Swing Daddy - 4 bike rack.

I am able to open the gate completely until it locks.


The two inch adapter was used on my wheelchair ramp to lower it for easier transport of the wheelchair on and off the ramp. The assembly itself was met without any problems. The only addition I incorporated was to use some WD-40
on the inner ridges of the adapter to allow sliding the adapter on easier.
I felt etrailer delivered a good product which was easy to use. I am a disabled 64 year old woman who is in great appreciation of your company.


I am giving it 2 stars only for the fast service by etrailer. The product alone I'm not happy with. Went to pick up our new RV and our Jeep's tow bar would only go in a 1/3 of the way. Seemed to be more than just paint. We had to force it in to get to the first hole just so I could get the Jeep home. I will be requesting etrailer take this product back.


Solved my problem of not enough spare tire clearance on the hitch-mounted storage rack I had bought. Solid construction, easy to use, as are the hitch pins and storage bag.

Everything has worked out fine. Weve used the equipment quite a bit since the fall for our bird hunting trips. Rather than use the straps on the bag I just secure it in the rack with bungee cords. Much faster to load and unload.

As always, E-Trailer never lets you down. This arrived on schedule and is of high quality as expected. We are using this to tow our "dingy" behind our motorhome. Love the Video's the E-trailer provides...makes for a smooth purchase experience, because 99% of all your questions are answered in the video.


I purchased a Roadmaster rise/drop hitch in order for my motor home to flat tow a Jeep Grand Cherokee more level. I searched the internet for the best prices on several hitch brands. I found the combination of Roadmaster and eTrailer to be very reasonably priced and of excellent quality. This is at least my third purchase of towing components from etrailer, and I have always had timely deliveries and very courteous support. I think I’m at the point of just shopping etrailer in the future, rather than wasting time comparison shopping.


Good quality... arrived super fast... I got free shipping as I added some safety cables to my order that I needed anyway... The Safety Cables are needed to extend my tow hitch safety cables for the added length of the drop down hitch and a Ready Brake that I use to stop my toad....


Wow, delivery was super fast on this 2" drop receiver. I ordered it Sunday night and received it on Wednesday. My roadmaster tow bar was slanting just under 3" so this should do the trick to get it closer to level. My only regret is that I forgot to order a second hitch pin to go with it, and had to run out to the store to buy one. :-)


Roadster makes very high quality products for towing vehicles behind motor homes. This product is used for leveling the motor home hitch to the tow bar from the towed vehicle. Construction, material and finish are excellent. eTrailer delivered this in two days. Excellent delivery and service from eTrailer.


As advertised, delivered quickly, very stout and sturdy built out of solid square steel, not tubing. Powder coated for great lasting appearance.

Very satisfied with this purchase.

Haven't used the quiet hitch yet, but it looks to be well made and engineered.


Perfect for my application. I needed to raise my tow bar connection to my car a couple of inches to help prevent the bar from dragging in low spots. This accomplished that and I very happy with the quality of the receiver extension.


Easy shopping, very good price and received it in a timely manner. Exactly what I needed. When I visited a local trailer/hitch company here in KC they had no idea what a drop hitch was. I was floored.

I would do business again with etrailer and would recommend to friends and family.


Needed a different drop hitch adapter due to new tow vehicle.
I have ordered many items from in the past, so this
was a natural place to begin my search.
The price was fair and shipping arrived just as stated when I ordered.

Would definitely purchase from again.


Very heavy duty. Works great on my motorhome with my Blueox towbar.


Amazing how one small, properly installed item can give you both practical and safe towing. Thanks to etrailer, I got it right the first time.


these parts are crucial to making trailers adapt to different tow vehicles

strong and durable I have confidence in the quality of these parts


Woks perfect! Great quick service from Etrailer!


Item appears to be very strong. The paint however was applied very poorly but it should my affect the performance.


Delivery was fast as promised. The hitch drop was just what the doctor ordered. It is heavy duty,and now I'm level. Thanks!


Holy moly....I could hook a CSX
freight train to this 2" drop receiver.
Deftly handled sale.

  • Line Pull Capacity Of Curt Front Mount Receiver On a 2015 Ram 2500 With Hitch Extender On Winch
    A 8" # 80307 or 14" # HE12 Hitch Extender will not lower the line pulling capacity for the Curt Front Mount Trailer Hitch Receiver # C31015 on your 2015 Ram 2500. Instead you will be limited to the tow rating of the extender which is going to be 3,500lbs for the 8" and 7,000lbs for the 12". If you use the extenders for a hitch mounted accessory or with a trailer is the only time the maximum capacity will be reduced with an extender.
