  • Tongue weight: 400 lbs
  • Gross towing weight: 10,000 lbs
  • Length:
    • 4-1/2" From center of hitch pin hole to angled brace
    • 7-1/4" From center of hitch pin hole to back of receiver tube
  • 1-Year limited warranty

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 Accessories and Parts RM-048-8 Review

Today we'll be reviewing RM-048-8, this is the Road Master High Low Hitch Adapter, traded at 10,000 pounds when it comes to weight capacity. It's going to have maximum ton weight of 400 pounds. This is designed to fit a two inch by two inch trailer hitch. The opening on the receiver itself is a two inch by two inch opening. If we take a measurement of the drop measuring from the top edge of the receiver tube to the top edge of the receiver tube it's going to give us a drop of eight inches. This can be used in the rise or dropped position, so if you flip it over to the rise position it's going to also give you an eight inch rise. Let's go over a few measurements real quick.

We're going to measure from the center of the hitch pin hole to the closest point here on the angle brace. That measurement is going to give us a measurement of five and a half inches. If we measure from the center of the hitch pin hole to the closest point here, that part that's welded on. That's going to give us a measurement of three and a half inches. The distance from one pin hole to the other, center on center, is going to give us a measurement of nine and seven eighths of an inch, and up top here we're going to take a measurement from the center of the hitch pin hole to the back of the shank, and that's going to give us a measurement of two inches. If you we're to go at a straight angle from one pin hole to the other, a forty five degree angle, you're going to come up with a measurement of about twelve and a half inches.

You can see here on the back side that this is a solid shank, it's a solid piece. It is going to require a five eighths inch pin and clip or a hitch pin and lock. We do sell those at, you can go to our website and type in part number PC3, it's going to refer you to a great option that's going to be a five eighths inch pin that's going to come with a clip. Please keep in mind that this is not for use with any type of trailer, this is designed for use with tow bars only. Again, it's going to give us a weight capacity of 10,000 pound with a maximum ton weight capacity of 400 pounds. That's going to do it for today's review of part number RM-048-8, this is the Road Master High Low Hitch Adapter.

Just received the order - everything was perfect! Fast shipping and appears to be a great product. Fits perfectly and solves my towing height issue. Being used with Blue Ox products (much less expensive option, and rated for more weight). Excellent value and customer service (called prior to my order, ordered via web, and received follow up). Will definitely use them again should the need arise! 130446


One year later and still very happy with my purchase as well as the service I had received. Great stuff!

Just what I needed - Bought a gently used Blue-Ox tow-bar to pull a recently acquired 1998 Honda Honda CRV with my 2005 Jayco Grayhawk. After installing the CRV baseplate (purchased from etrailer, another great buy, installed myself in about 45 minutes) the vertical alignment of the base plate connections and the RV's receiver hitch was 9-inches off. I found this hitch adapter, it arrived within a few days of ordering even when I ordered it less than a week before Christmas. A test tow around the neighborhood proved all worked and aligned great. etrailer team followed up, provided info on shipping status, all-in-all an excellent transaction. 167517

Originally ordered a 10" High-Low Hitch Adapter and needed a 7-day (maximum) delivery date to stay on my departure schedule. etrailer responded within one day to say that there was a manufacturer's delay but they had 8" adapters in stock. This would work, so we changed order and it shipped before end of that day. I received order from UPS yesterday (one day before due). Quality, appearance and application looks great. We'll be on road on schedule and see if performance and fit meet my plans and expectations. So far, so good. Thanks. 55383

Product was just as advertised and made my Class "C" RV hitch and 4WD towing setup exactly level. Hi/Low Extension was top quality. Very satisfied with the product and prompt delivery. I am a multiple time purchaser through "etrailer" and every experience has been top notch. Seller is highly recommended!! Do note that Hi/Low Extension extended overall tow setup an additional 10" and therefore also required the addition of safety cable extensions and a new longer wiring harness. 254440

Spoke with Michele at in the early afternoon and she told me the Roadmaster adapter was in stock and could ship as soon as the next day. Later that afternoon I received an email that the adapter had already been shipped with an estimated delivery date. Adapter arrive one day earlier than estimated delivery date. Adapter was exactly as advertised. The price was the best I could find anywhere. Very happy with the service, price and quality of product. 253122

wow, I had tried to order this part about a year ago, the order went through and 40 days later I called and was told it was out of order, so, tell me, how do you sell something you don't have?, and I went my way. I decided to try again and this time got the part in 4 days, very good etrailer, I may be a returned customer now again. Part is great, super heavy duty, 31lb it will add, but I am sure it will work just fine on next trip. thanks 204575

There were some hang ups on my original order as the product wasn't in stock so the people over at eTrailer worked their magic and got my order shipped much faster than anticipated. The customer service at eTrailer is amazing and I would use them again for sure! Please keep in mind this particular riser doesn't come with a hitch pin so make sure you include that with your order. 273592

I'm refurbishing a 1996 truck camper and luckily needed exactly 8 inch rise from my truck hitch. This will allow me to use a cargo carrier for my generator. This product is solid and I recommend it (and other sizes like it) for your hitch. I paid a few extra dollars to get it in 3 days, right on time. George from etrailer updates my orders via email, excellent service., 384394

This product is fabricated well. The finish is durable, the welds are substantial and neat, as I have come to expect with Roadmaster products. As always, the service from Etrailer was quick with shipping updates and status. The parts arrived well packed using a stout carton with handles, thus no damage to the carton or contents. Etrailer knows how to pack and ship! 82548

Great hitch adapter...well built and sized as advertised. I was disappointed with having paid $30 extra shipping for 3 day delivery, only to have it take 6 days to arrive, from the time I was notified that it had been shipped. This delayed our leaving on our trip by 2 days. etrailer has always delivered great products and service; not sure what happened this time. 404197

This is a RoadMaster product and eTrailer got it to me in a few days. I was a bit surprised that the shear pin hole was so far out on the shank. I ended up drilling another one 4 inches toward the tail and will use that vs the stock hole which will reduce the stress on the receiver tube and also help a little in ground clearance over dips. 217872

- RM-048-8

by: Tom S.04/14/2015

The riser worked well as advertised. I will be using it with the folding cargo carrier I bought from etrailer a week or so ago. With the riser on the mobile home it gives the carrier clearance so it doesn't hit the ground. It also now allows me to fold up the cargo carrier. It was too close to the mounted spare tire previously. Nice. 185116

The product solved my problem by lowering the attach height on my motorhome making it level with that on the vehicle being towed. 250920


I feel that the design limit for the torque this attachment imparts on the motorhome trailer hitch exceeds the design limit of the motorhome hitch. A few hard stops seem to have bent the motorhome hitch a little. I am towing a 4k lb vehicle with a 2015 Winnebago Vista.

Walter - 05/21/2017


Thanks for the feedback. It is always that the lowest rated component of the towing system be the determining factor for any towing situation. I looked on-line and it looks like your 2015 Winnebago Vista could have been equipped with a hitch rated for up to 5K from the factory. Please confirm that the hitch is rated appropriately for the vehicle you are towing. Additionally a supplemental braking system like the Roadmaster Even Brake # RM-9400 is recommended. If you do have a braking system it may need some adjustments for more effective braking of your toad. I have also included a link to one of our help articles that explains all the individual components of a flat towing system for your reference.

Just received it today. I like the solid steel shank and seems to be well constructed. I put my Delco Commander tow bar on it and wouldn't slide in all the way. I just had to tap it in and it was good. In a way that's good because there's no play in it to cause sway. My Jeep should tow perfectly level now. 396351

This is something I need and etrailer has a number of different sizes and the one I picked was an 8" unit. This should work fine on rising my Hitch carrier to he right rise from the ground. The 3 ball carrier is something I ordered in hopes I can store my interchangeable balls 36043

I use a 4" drop down for my mobility scooter carrier. My SUV hitch was too high to allow me to run the scooter up onto the carrier. The drop down made the carrier hight perfect. The drop down is strong and very stable. Noe I can travel and be moble at my destination. 413827

This drop down is so much better than we expected. It's well made, heavy duty and made the wheelchair carrier so much better. Now my power wheelchairs go up onto the carrier easily. No more fighting with the chair to go onto the carrier ramp, which was way too steep. 127038

Do you have a question about this Accessories and Part?

  • Can a High-Low Trailer Hitch Adapter # RM-048-8 be Used To Raise up a Cargo Carrier
  • The Roadmaster High-Low Hitch Adapter, # RM-048-8, is only designed for tow bar applications. I do have another, more cost effective solution. You could use the Curt Multipurpose Ball Mount, # D210. Though it is designed to tow while carrying a cargo carrier or bike rack, you can use it to just carry a cargo carrier. The rise on the receiver is not as high as the High-Low adapter, but the receiver portion has a 350 lb tongue weight.

  • Towing a Trailer with a Coupler that is Higher than the Trailer Hitch on a Jeep Wrangler
  • All you need is a ball mount that allows you to tow the trailer level. You can measure for the amount of rise needed to select the correct model. A ball mount with rise is needed when the trailer coupler is higher than the hitch receiver on the vehicle. Have the trailer and the Jeep Wrangler parked on level ground. Disconnect the trailer from the Jeep. Measure from the ground to the top of the hitch receiver opening. Then use the trailer jack to make the trailer level and measure from...

For a 10 inch drop use part # RM-048-10. For an 8 inch drop use # RM-048-8, for a 6 inch drop use # RM-048-6, for a 2 inch drop use # RM-048-4 and for a 2 inch drop use # RM-048-2.

  • Availability of Hitch Extension To Keep Pickup From Hitting RV When Being Flat Towed
  • The Roadmaster High-Low Hitch Adapter, part # RM-048-8, will extend the truck further away from the RV, but it will also change the height of your tow bar connection. It has a 8 inch rise or drop which will either raise or lower the tow bar connection of your pickup to the RV. If you have a level connection now you will not want to use the # RM-048-8 to extend your vehicle away from the RV. The end of the tow bar that attaches to the base plates on the vehicle should not exceed a rise...

  • High/Low Adapter with an 8 Inch Drop to Flat Tow a 2012 Chevy Equinox and Bike Rack Recommendation
  • The dual receiver we have with the most rise or drop is # RM-077-4 that you have referenced. One of the receivers has a 4 inch drop. That is not quite enough if you need 8 inches. But there are other options. First, you do need an 8 inch drop so that is a given, use # RM-048-8. This adapter has a 10,000 pound gross towing weight capacity and 400 pound tongue weight capacity. What you can do is add a trunk mount bike rack to the 2012 Chevy Equinox. There are 2 and 3 bike carriers...

  • Recommended Cargo Carrier For Front Hitch On 2012 Chevrolet Suburban 1500

If you choose an adapter in your hitch you need to note that using an adapter will reduce the hitch carrying capacity by 50 percent. Part # BX88241, part # BX88131, part # RM-048-8, and part # RM-048-10 are all designed to be used for flat-towing only and are not designed to be installed in a front hitch...

  • How to Carry 320 Lbs. Scooter on Front of 2016 Ram 2500
  • It sounds like you've already got everything figured out. As long as your 2016 Ram 2500 has the factory tow hooks you can install the Draw-Tite Front Mount Trailer Hitch Receiver # 65063. The MaxxTow MaxxHaul Aluminum Motorcycle Carrier # MT70101 will carry up to 400 lbs. and the hitch receiver is rated for 500 lbs. You will want to verify that the front axle weight capacity of your truck is enough as well because you will be limited by whichever piece is rated the lowest. You can...

  • Parts Needed for Flat-Towing 2002 Kia Sportage
  • Safe and legal flat towing of a vehicle behind a motorhome requires a few components, all of which are detailed in the linked article on the basics on flat towing. Additional articles are included too to help you with your selection of a braking system and high/low hitch adapter. Typically, a flat towing set-up includes a tow bar, high/low hitch adapter, safety cables, a wiring/lighting solution, and both base plates and a braking system for the towed car. Starting with base plates,...

  • Which High-Low Adapter For Honda Odyssey being Flat Towed Behind 2008 Bounder 35H
  • Since ground clearance is limited and the part # RM-048-8 will get you within the 3 inches up and down of being level that would be your best option. I attached a help article on how to pick out the correct high-low adapter as well.

  • Can High/Low Hitch Adapter Be Used with Yakima Four Timer Hitch Bike Rack
  • Hitch adapters like Roadmaster high/low adapter # RM-048-8, which provides 8-inches of rise or drop, will give you more clearance but all such adapters also cost you half of your hitch's rated capacity. The loss of hitch capacity from use of an adapter results from the longer distance between the hitch tube and the actual load. Extending that distance applies more leverage on the hitch tube and this results in the hitch being able to handle only half as much weight. If the combined weight...

  • Low Hanging Front Mount Hitch Recommendation for a 2013 GMC Sierra 2500HD
  • You can use a high low adapter like part # RM-048-8 to lower the hitch opening but you should note that it will lower the capacity of the hitch by 50 percent. I attached a picture of the Curt Hitch part # C31023 installed and you can see it sits a bit closer to the ground. This might be your best option since it wouldn't require the use of the high low adapter.

  • How Level Does Towbar For Flat Towing Vehicle Behind Motorhome Need to Be
  • According to Blue Ox and Roadmaster, you want to use a High/Low adapter that would place the tow bar's attachment to the hitch no more than 3 inches above or below level. Anywhere WITHIN that range would be perfectly acceptable.

  • Can a Roadmaster High-Low Adapter be Used with a Kawasaki Mule for Off-the-Road Towing
  • If the trailer has a regular coupler that fits on a ball then the best solution is a ball mount with the proper rise. I really cannot recommend using any of the High-Low adapters for anything other than flat towing a vehicle, even if it could work. But it sound like a ball mount with the proper rise is the ideal solution. The ball mount we have with the most rise is # AMSC12. It has 10-3/4 inches rise. But something like # 80248 with 9-3/4 inches might be better. I have included a link...

  • Using Mobility Chair Carrier on Taller Vehicle That Has a 2-Inch Hitch
  • We do offer a range of high/low 2-inch hitch adapters like the Roadmaster # RM-048-8 that provides 8-inches of drop or rise. The trouble with adapters is that they have the unavoidable side-effect of cutting your hitch's capacity by 50-percent. This is a result of the change in geometry and leverage that occurs from adding in the adapter. Let's say your hitch's safety sticker indicates a tongue weight (TW) capacity of 500-lbs. If you were to use an adapter you'd end up with a halved...

  • Recommended Blue Ox Flat Towing Set-Up for 2015 Chevrolet Colorado
  • Our installers really like the Blue Ox flat towing gear for its consistently good fits and reliable performance. And in general if you stick with one brand for your base plates and tow bar you can avoid the complication and expense of the adapters needed when you mix parts from different manufacturers. We offer the Blue Ox base plate kit # BX1721 for your 2015 Chevrolet Colorado. This features easily removable draw bars. With these I recommend the Alpha motor-home-mount tow bar # BX7365...

  • Recommended Adapter For Greater Ground Clearance For Bike Rack On 2016 Honda Odyssey
  • For your bike rack on your 2016 Honda Odyssey, I recommend the Curt Dual 2" Receiver Tube Adapter, 8" Extension # D-192. This is rated for up to 350 lbs tongue weight but will reduce your trailer hitch tongue weight by up to 50%. So in most cases for a Class III hitch that reduces your total to 250 lbs tongue weight with will be fine for a bike rack. This gives you the option to tow a small trailer as well. High-Low adapters can be used for bike racks but they also reduce the hitch...

  • How To Determine What High-Low Adapter Is Needed When Flat-Towing
  • You want the tow bar to be as level as possible to tow the vehicle safely. To find out what high-low adapters you need to flat tow you can take a couple measurements.You can park the towed vehicle on level ground and then measure from the ground to the bottom of the base plate arms that attach to the tow bar. Then just measure from the ground to the top of the receiver opening on the RV. If the RV receiver is higher as you mentioned, the difference is the amount of drop you will...

  • Lowering 2 Inch Trailer Hitch Receiver when Using a Motorcycle Rack
  • First you need to know that the use of an adapter to extend, reduce, raise, or lower the receiver will reduce the tongue weight capacity by 50 percent. So if the motorcycle rack you have is completely supported by the trailer hitch then the combined weight of it and the bike cannot exceed the reduced tongue weight capacity. So for example if the combined weight of the carrier and bike is 350 pounds then the hitch would have to have a tongue weight capacity of at least 700 pounds. In...

The kit fits your 2014 Jeep Wrangler that has the off-road bumper with 3/4 inch thick D-Ring bumper mounts.

  • Can the Roadmaster Quiet Hitch Be Used for Flat Towing using a Class IV Hitch and High Low Adapter
  • The Roadmaster Quiet Hitch # RM-061 would work great for your application as long as your Class IV hitch and the high low adapter are both 2 inch hitches. The Roadmaster 8 inch high low receiver that we currently have # RM-048-8 is a 2 inch receiver. For your application you might want to consider using 2 of the Roadmaster Quiet Hitches, one for the receiver at you truck and one for the receiver on the adapter. For your reference I have also included a link to a helpful article...

  • Weight Distribution Shank or Ball Mount with 8 Inch Drop to Tow Airstream Level with 1998 Suburban
  • It sounds like you are using weight distribution (levelers) so you would need a shank that offers enough drop to tow the trailer level. Curt weight distribution shank # C17124 offers 9-1/2 inches of drop on round bar weight distribution systems and 7-1/2 inches for trunnion bar systems. The holes in it are 3/4 inches in diameter and spaced 1-1/4 inches apart on center. If you know what weight distribution system you have I can determine if this shank is indeed compatible. If by levelers...

  • Recommended Base Plates for Flat Towing 2005 Jeep Wrangler

Jeep base plate fits are shown on the linked page. Just select the type of bumper you have using the drop-down menu tool at the top of the page. I suggest you try to use base plates from the same maker as your tow bar since this will reduce the complexity and cost for the set-up; if you stay with one brand you'll not need adapters to join...

  • Parts Needed for Flat Towing 2006 Jeep Grand Cherokee
  • If a tow bar like the Roadmaster StowMaster # RM-501 is properly maintained, kept clean and protected during storage periods then it could be perfectly fine. If the tow bar is 10 years old and has never been serviced then a rebuild kit may be in order. For the Stowmaster RM-501 the rebuild kit is part # RM-910003-20. We offer tow bar cover # RM-052-3 for the StowMaster. For a compatible set of base plates I recommend Roadmaster's XL base plate kit # 1427-1. These work with the StowMaster...

  • Can the Roadmaster High-Low Adapter Be Used with Kuat Bike Rack for Rear Hatch Clearance
  • The Roadmaster High-Low Adapter # RM-048-8 can be used with a bike rack. However, 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. For example, if your vehicle's trailer hitch has a tongue weight rating of 350 pounds, when using the high-low adapter, the hitch can only handle 175 pounds of tongue weight. This reduced tongue weight includes both the weight of the rack and the weight...
