Make up for the height difference between your RV and towed vehicle with this hitch adapter. Provides either an 8" drop or an 8" rise. Solid shank provides strength and durability.
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.

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 etrailer.com, 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.

The hitch is A1 , just as advertised. It was shipped out the day after I ordered it and arrived in Canada in a week , very pleased as we have used this company before and will again in the future. 150703

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

Needed in a hurry, but did not opt for higher priced shipping. Item was shipped same day, and arrived fast. Very satisfied. I had previously ordered a bike carrier and was pleased to return. Best prices and fasted shipping. Will continue to use for my RV needs. 121742

Always get good products and great service from etrailer.com 194257
This is a super product! It is substantial, and works perfectly. We had a large height difference between our tow vehicle, a Mazda Miata, and our RV. We took it one step further and welded our bike hitch to the top and have solved that problem also with this one product. Highly recommend. 249531

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 etrailer.com 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

Just received the Roadmaster 8" High-Low Hitch Adapter today and the quality looks awesome and etrailer was awesome to deal with super fast shipping and good communications, and I'm sure this is going to work just fine when I get ready to use it thanks etrailer. 65366
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

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
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
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 am using this 8 inch lift to increase ground clearance for my snow plow mounted on a a front 2 inch receiver for a 2013 Chevy Silverado1500. It works perfectly as expected. I use it in a residential application only for a couple long driveways including my own. A solid heavy duty implement. Thank you!! 238188
Turned it over and it raises my towbar on the motorhome so I may safely flat tow our Jeep 28855
by: Willie M04/03/2012
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
Fit great and was delivered in 3 days just in time for my travel. High five :) 232564
by: Mike S04/21/2014
Great service in getting the item I needed. The hitch adapter arrived sooner then what I would have thought it would have. Works great while towing my Jeep. The service at etrailer was great and I know where I will be buying all my needed products for my RV, yelp at etrailer! 126122

internet rv parts I looked long and hard and etrailer.com is the best,most accommodating,on the ball, of any rv parts supplier I dealt with on the internet.I live in Oregon and bought from etrailer in Missouri.That should tell you something I highly recommend them.......Don F. 5032
by: Joe E.06/18/2014
The product exceeded my expectatiions in quality and my customer service experience was outstanding. Marcia A. assisted me over the phone to identify the part I needed and expedited the order. She even called back to update me on my product. Overall I am very pleased. 136213
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
by: JR R.06/04/2012
Great service. The 8" adapter wasn't in service, but I asked to switch my order to the 6" adapter so I could begin using the product immediately. The customer service staff switched the order immediately and shipped the product! A+ on customer service! 42740
by: Don W07/17/2014
Ordering experience, delivery and follow-through on the part of this company and especially the sales agent was excellent. Part looks great and fits the motorhome hitch perfectly. While I haven't connected the towbar yet I do not anticipate any issues. 141796
Exactly what I needed to do the job. Shipping from etrailer to my address has been nearly unbelievably fast for ground delivery. Mostly 3 days! Could be the zip code, don't know. Thank you for the outstanding services provided now and in the past. 147765
by: Charles Herrington12/05/2012
Looks very good and the shipping was excellent. It came 1 day before i expected it and just in time to use it. I pulled my car with it and it kept the towbar and the car level with the motorhome and worked perfect. Thanks for the fast shipping. 60722
by: Sylvie P.12/17/2014
worked out perfect but would have like the hole to be a little further back to avoid end play. I called Roadmaster and was told I needed 2 "magic hitch" parts which I think is redundant. As for YOUR service, shipping, etc it was excellent! 165763
Looks like the high-low hitch adapter is just what I need to raise my rod rack higher for surf fishing and driving on the beach. They even shipped it in 3 days time rather than the 7 days I paid for...at no extra charge. 66940
by: Alan B02/09/2015
Easy to find and understand the product based on the description. Reviews were very helpful to help me make sure I was getting the correct item. Delivery was right on time and they even included free shipping. Thanks 173033
by: Andy and Robin12/02/2014
It feels sturdy enough to tow a 53 footer with. A little overkill for my purpose but I will never have to worry about it. Also adds a little weight for snowy days! Fits great but got a stabilizer just to be sure. 163044

Your reps did excellent job except for one suggestion. The High-low Hitch Adapter does not come with the Hitch Pin. This should be mentioned as you must have the Hitch Pin. Keep up the good work. Richard B. 105093

The folks at trailer have been fantastic at helping me put a towing package that fit my needs. Great price, high quality products and excellent customer service means they are my go to for any towing needs. 300028
by: rob a08/08/2016
Not only did they have the part I needed in stock, but they were able to ship it out same day, while;e we were traveling, to our next stop, so we could continue our trip unencumbered. They saved the day! 281602
great product and an even better price, especially on a free shipping promotion, Ordered Feb 23 it arrived morning Feb 26. Great service from etrailer - again, always my go to for trailer/towing stuff. 176178
by: Scott J02/02/2015
Haven't used the product yet, but it is clearly capable of doing the job it is intended to do. Very heavy duty and well constructed. I'm sure that I will be extremely satisfied with my purchase. 172204
by: Roger R.09/16/2014
Well built and more than meets my needs. I do not like to purchase a product that is on the boarder line of meeting requirements and this exceeds my requirements. Thanks for all your assistance. 151337

It is a pleasure to purchase from a company that really cares about their customer. Jean at etrailer.com was 100% in her care for my return on a part that was my fault. This is a great company. 160742

Great informative videos to help make sure your ordering the product you need for your needs. Products are made of quality materials. I will definitely be ordering from etrailer again!!!! 245537
What a great company to work with. Our receiver was received earlier then we thought - packaging was excellant. Will definately use this company again & recommend them to others. 133668
Good price, no shipping cost and the item was shipped quickly. The sales person that I talked to was well informed and very helpful. I would definitely purchase from them again. 132466

Heavy duty piece of metal. It is pretty hefty. Using it to pull a vehicle that is low to the ground, which is why I needed an 8" drop. Exceptional quality. Highly recommend. 251226
Product is working great. I am using it to pull my camper and my truck has a lift on it. So this levels me out. Great product. Heavy built. No complaints. Thanks guys. 202704
You can't go wrong with Roadmaster products. The drop receiver is very well built and eTrailer has never failed me with their great customer service and fast shipping. 299389
We found the hitch that corrected the height between our tow vehicle and motorhome. We ordered it and it came as was advertised and at the designated delivery date. 220017
Thank you so much for such a quick reponse in sending us our hitch. It is great in fact better quailty than we expected. We will definitly use your company again. 72137
