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.

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 for high or low ground clearance. Hollow shank is lightweight.


Very, very good quality product. It works perfectly for towing my Jeep Wrangler with a good room of towing capacity for extra safety. I also purchased the Towmaster locks to go with this and they are of super good quality too. Just push on the locks and you're good to go.



Have been using this adapter for a year now and the quality of the product still astounds me! Well built, sturdy and still looks great!


Had to put on Motorhome because Jeep was 4" higher and roadmaster recommends tow bar to be within 3" high or low. Had to extend safety cables


Perfect height Towbar level


Just received, but looks like it will be perfect for dropping my RV hitch height 2" to match up with the baseplate on my Jeep Wrangler. Ordered on Sunday and here by mid-day Wed with regular shipping. Hard to beat that! 4th time I've ordered from Etrailer and very happy with the fast service, great pricing, and excellent descriptions that they provide online.

Michael D.


Great! Does just what it needs to do.


The locking pins keyed alike while be convenient! The 2" drop/rise adapter according to the label stuck to it says it is only rated for 100lb tongue wt, but your item description says 200lb tongue wt??.

Roadmaster has recently completed further testing that has found that the TW capacity of the RM-072-2 is 200 lbs. Going forward, they will be stickered with the new capacity, but the older examples are safe to use with up to 200 lbs of tongue weight.


Excellent!! Just what I needed. An extension to lower my Thule bike rack to allow my back jeep door to swing open.
Locks to jeep, secure couldn’t ask for a better solution.


Placed order with Road Master for this Road Master High-Low Drop and they notified me it would be two to four weeks. Canceled order with Road Master and ordered from etrailer. Ordered on Monday and received on Thursday. The two inch rise and ten inch extension was exactly what I needed to pull my CRV behind my B-Plus RV. Needed to raise tow bar two inches to have the three inches minimum height difference and the ten inch extension was needed to clear bicycle rack. Actually called etrailer B4 ordering and talked with a very nice and courteous lady. Thanks etrailer, you made my day.


This works perfectly for lowering the hitch height and increasing distance so that my buke rack can fold down and out of the way of my jeep's tailgate.


Old 4" drop hitch was too much for the right fit with our new car. Not everyone carries the 2" drop hitch. We're close to etrailer's supply center and the order was delivered the day after I placed it. Great service and the fit with the towbar was just right!


I am using this to level out my Jayco Jay Feather travel trailer. It did not have enough clearance in back for me to back into my driveway. It does now.
David M Smith Sr


The offset is a bit longer than I expected. But after I installed it I was able to still use my safety cables and wire harness. The offset I believe will help a lot with handling while pulling my Jeep behind the motor home.


5 stars all the way. Installation instructions were very good. Everything worked out perfectly and I am very happy with the entire unit. I also appreciate that Steve at etrailer was always available to answer any questions I had.


disappointed that I paid this much for a hunk of metal and it didn't include a hitch pin.

We do have hitch pins available. I recommend hitch pin part # C21510 or for added security lock part # e98881.


This is my second order, and both times the delivery time was great. It was delivered at my door step and I didnt have to go driving around town looking for what I needed. Pricing has been excellent on the Items also. I have already setup the receiver and it was exactly what I needed.



exactly as described!Teresa at E-trailer took goofd care of me and my prder shipped immediately. My second order from E-Trailer and wont be my last!


This is just what I need to flat tow our Jeep. Very good product.


Found the product easily on the etrailer web site. Price was better than most other sources. I had to speak with customer support three times and each time they were outstanding....polite, helpful, and efficient. Product was shipped quickly and arrived sooner than expected.


Unit was ordered along with a Falcon All-Terrain tow bar. Both arrived 3 days before expected. Excellent quality at a reasonable price. Shipping service was great.


The RoadMaster High-Low Drop-2" was of high quality material and finish. I was in a bind and etrailer came through with quick delivery.

Happy Camper ;)


Overall, pleased with quality of the hitch and exceptional service.



Hitch is working just fine. Many thanks. Bud


As always, e-trailer has provided me another quality product with fast shipping. After doing numerous searching, etrailer had the best product price along with the most reasonable shipping costs.


The quality and durability of this drop receiver is top notch. I am using it for my motorhome to auto to connect for towing the auto.


Your service/sales techs are very good! How refreshing!

The RM High-Low fits my Motor Home perfectly and your delivery time is excellent. Plus your prices were the best. One cannot beat a combination like that.

Thank You!


Was exactly as advertised.


Perfect. Now my hitch is out from under the bumper and easier on my old back when hooking up.
Thank you.

  • Is A Hitch Extension Available For A Class III Hitch With A 2 Inch Rise
    The Roadmaster High-Low Hitch Adapter, part # RM-072-2, is a hitch adapter that is used for tow bars only. It is not to be used with any type of trailer. It is used to level the tow bar with the vehicle being towed. This adapter fits a 2 inch receiver and will give a 2 inch rise or drop. The overall length of the hitch adapter is 14-3/4 inches and the measurement from hitch pin hole to hitch pin hole is 10-1/4 inches. I am including a link to the tow bar hitch adapters with a 2 inch rise. The...

  • Pin Hole to Back of Receiver on Roadmaster High-Low Hitch Adapter # RM-072-2
    I went out to the warehouse and pulled Roadmaster High-Low Hitch Adapter # RM-072-2 to measure it. From the center of the hitch pin hole to the back of the receiver portion of it measures 6 inches. And on the other pin hole at the end to the back of the receiver is 4-1/4 inches. The main shank is solid and the receiver portion is open at the back.

  • Can High-Low Adapter be Used for Motorcycle Carrier
    Although you technically can use the Roadmaster High-Low Adapter # RM-072-2 to mount an accessory like a motorcycle carrier, the use of ANY adapter will reduce the tongue weight of the hitch on your vehicle by 50 percent. So if your hitch has a tongue weight capacity of 500 lbs the use of an adapter such as this would lower the capacity to 250 lbs and your bike and hauler would be too heavy. So essentially, unless you have a hitch with a tongue weight capacity of 800 lbs you would not...

  • How To Raise Motorhome Hitch 2" for Tow Bar
    Yes, the Roadmaster High-Low Adapter for Tow Bars part # RM-072-2 can be used to turn the 4" drop into a 2" drop if used in the rise position.

  • Anti-Rattle Device Recommendation for Use with Roadmaster High-Low Adapter
    Since the Roadmaster High Low Adapter part # RM-072-2 that you referenced has a solid shank the type of anti-rattle device you would need is one like the # RM-061 which clamps around the shank and the opening of the hitch. I attached a review video for this for you to check out as well. You should also note that when you use a hitch adapter like the extender you referenced you end up cutting the tongue weight capacity of the hitch in half so you would need to be aware of that as well.

  • Compatibility of Spare Tire Carrier with Hi Low Adapter
    I called Roadmaster, the tech informed me that they do not recommend these two items be used together, he also mentioned to me that it would be unsafe. One solution I came up with would be to put the spare tire carrier on the back of the towed vehicle. If you would like to provide me with a little more information about your towed vehicle, I would be more than happy to recommend a hitch setup for you.

  • Dimensions Between Hitch Pin Holes on Roadmaster 2 Inch Rise/Drop Adapter # RM-072-2
    The Roadmaster 2 Inch Rise/Drop Adapter, part # RM-072-2 and the Roadmaster 4 Inch Rise/Drop Adapter, part # RM-070 has a measurement of 10-1/4 inches between the center of both hitch pin holes. So if you measure on your hitch receiver from the center of the hitch pin hole out to the rear of the vehicle, the measurement listed above will give you an idea of how far out the adapters will be from your hitch receiver.

  • Can a Tow Bar be 3-1/2 Inches Out of Level when Flat Towing a 2012 Jeep Liberty
    The problem is that the tow bar can only flex so much and if it is 1/2 inch out of the safe zone now then it will be out much more when on uneven terrain. You will want it to be as level as possible. To get a more level set up you can use a high/low adapter to compensate for the 3-1/2 inches of difference between the base plates and the hitch. We have a 4 inch option, # RM-048-4, that will get you closest to level. Or if you want to be in the safe zone you could use a 2 inch drop model...

  • Height of Roadmaster Cross-Bar Style Base Plate Kit on 2018 GMC Canyon
    With the Roadmaster Crossbar-Style Base Plate Kit # RM-523182-4 installed on your 2018 GMC Canyon the tow bar will be mounted 17-1/2 inches off the ground. Keep in mind this measurement is assuming your Canyon is equipped with the stock 265/60R18 size tires. Based on the 20 inch height you mentioned for the hitch on your RV you will technically still be in the "Safe Zone" (within 3 inches above or below level) without an adapter but to get even closer to level you will just need the Roadmaster...

  • Hitch Adapter with 2 Inches of Drop to Get a Cargo Carrier to Clear Spare Tire on a Jeep
    You can use Roadmaster high/low adapter # RM-072-2 which offers a 2 inch drop. However, the use of this adapter (or any adapter) reduces the tongue weight capacity if the hitch by 50 percent. So for example if your hitch is rated for 350 pounds tongue weight it is reduced to 175 pounds when using an adapter. So the combined weight of your cargo carrier and the cargo cannot exceed the reduced capacity.

  • Height Adjustment Range of Demco Excali-Bar III Tow Bar
    The Demco Excali-Bar III Non-Binding Tow Bar - Victory Series - RV Mount - 2" Hitch - 10,500 lbs # DM9511013 you referenced is an excellent tow bar and it has an integrated height adjustment in the shank. This will allow for 1-1/2 inches of rise or 1-1/2 inches of drop depending on the orientation of the shank. Most tow bars simply have a straight shank. When flat towing, you are correct that your tow bar needs to be within 3 inches of level for safe transport. Most tow bars will require...

  • Hitch Adapter Needed with a 6 Inch Extension and a 2 Inch rise
    The Roadmaster Dual Hitch Adapter, part # RM-072-2, may be what you are looking for. It is designed for tow bar use only and is not to be used with any type of trailer. This adapter fits a 2 inch receiver and will give a 2 inch rise and drop. The overall length of the hitch adapter is 14-3/4 inches and the measurement from hitch pin hole to hitch pin hole is 6-3/4 inches, which is the amount of useable extension when installed in the receiver.

  • Tow Defender Recommendation for 2008 Mazda Miata Being Flat Towed with Roadmaster Falcon Towbar
    The Roadmaster Tow Defender part # RM-4700 that you referenced will fit your Roadmaster flat towing setup that consists of a Falcon 2 Tow Bar part # RM-520. On your Journey DP we had a customer come back and say that they had to use a high-low adapter to get the exhaust to clear guard. They used the part # RM-072-2 to accomplish this.

  • Hitch Pin and Lock Recommendations for Roadmaster High/Low Adapters
    The High/low adapter # RM-072-2 does not come with a hitch pin. It takes a 5/8 inch diameter pin or lock. For a regular pin and clip you can use # PC3. For a lock you can use # RM-316 which is a set of 2 that are keyed alike.

  • High/Low Hitch Adapter to Keep Nighthawk Tow Bar RM-677 Level for Best Operation
    Roadmaster does specify the 3-inch safe zone for tow bar height differences at the motorhome and toad ends. Really any tow bar will perform better when it is level since there will be less arm tube friction. A level tow bar will also endure less mechanical stress and it will put less stress on the base plates, the towed vehicle's frame and its suspension. Since you have invested in the Nighthawk # RM-677, one of the best tow bars available, I recommend you protect your investment and...

    Over time the AutowLock buttons of the Roadmaster Falcon 2 Tow Bar # RM-520 can wear out and need to be replaced. The good news is that we carry a repair kit for this to get it back to normal. For that you would need the part # RM-910003-60.

  • Can Lower Square Tube on Kuat Pivot be Used with Accessories
    The lower square tube on the Kuat Pivot # PVP20B is not designed or rated for use with any type of accessory. It also is not set up for it (no pin holes) so it is not a good option for your application. We do have adapter # RM-072-2 which has a 400 pound tongue weight capacity and 2 inch drop. However if you use it or anything similar it will reduce the tongue weight capacity of the trailer hitch by 50 percent.

  • Hitch Adapter to Raise Cargo Carrier by 3-4 Inches
    What you're describing is called a high-low adapter. They work very well keeping the tow bar level when you're flat towing a vehicle, but they can also be used for elevating a hitch mounted accessory. Another option would be the Roadmaster # RM-077-4 dual hitch receiver offers the rise you're looking for. The pin hole to pin hole dimension is 10-1/4 inches which is slightly longer that you wanted, but it should work just fine for you. A third alternative, the Curt # D-192 offers a bit...

  • Trailer Hitch Adapter To Both Raise and Extend Motorcycle Carrier on an RV
    I do have some options for you but what you need to keep in mind is that hitch adapters reduce your tongue weight capacity. If you are only trying to carry a small dirt bike then I think we can get away with an (up and out) hitch adapter but if you have anything much heavier you are just going to need to place it on a trailer because it's just not safe to place that much weight on the back of a hitch with an adapter like the above. The best options we have for a small motorcycle are going...

The SuperSprings Custom Suspension Stabilizer and Sway Control Kit part # SSA11 which is what I recommend will prevent the motorhome from sagging therefore increasing clearance but again nothing we offer will raise the rear of the motorhome from stock.

  • Which Hitch and Bike Rack Should I Get To Carry E-Bikes On My 2014 Dodge Challenger?
    First let's get a hitch that will fit with your Borla exhaust but also have good ground clearance. The Curt Hitch Reciever Part # C13236 will give you 9-1/2" of ground clearance. Now, let's find a rack with the most ground clearance. The Inno Tire Hold 2 is going to be able to carry two electric bikes with a weight of 50lbs so you will be plenty good when it comes to weight capacity. This Rack has a rise in the shank so it sits higher than your hitch receiver when hauling. If you are still...

  • Can Hitch Extender be Used with Kuat NV 2.0 to Clear Spare
    Extenders can be used with bike racks but you need to keep in mind that doing so cuts the capacity of the trailer hitch in half. The part # HE06 would fit your 2 inch hitch and provide 7 inches of additional extension. As long as your hitch is rated for the weight of Kuat NV 2.0 # NV22G and bikes this would be a feasible solution.

You might be able to use part # HE18, which is a hitch extender. This item adds 18 inches to the length of the receiver but also cuts in half its tongue weight capacity. You will need to make sure that the combined weight load of what you intend to place in your vehicle plus the weight of your towed camper does not...
