Specs:
- Application: 2" x 2" trailer hitch receivers
- Drop/rise: 8"
- Receiver: 2" x 2"
- 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
- 10-1/2" From center of hitch pin hole to center of hitch pin hole

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 works perfect when I hook up my 2022 GMC Canyon (Stock height) to my motorhome to maintain level tow bars.

Christy is a fabulous sales person. She took care of me like a pro. Everything fit perfectly or both holes lined up. I’ve towed a couple thousand miles with it. I couldn’t be happier. Thank you for the service. You’ll always be my go to for trailer parts and towing parts. Have a great holiday. Happy Thanksgiving and God bless.

The hitch adapter arrived on time. A bit pricey, but very high quality. Amy was very helpful in selecting right product.

Perfect adapter to tow my trailhawk. I use it to raise the tow bar so trailhawk to the tow bar are level during towing. I do recommend this adapter.

Etrailer is always very responsive and very knowledgeable with their products and customer interaction. I would highly recommend them as a first point of contact for product and product recommendations.

Still works great although we bought a newer jeep and don’t have to use the product with it. We have the flexibility of being able to tow either jeep by having this adapter.

The only thing I have changed is to have an additional receiver welded on top to carry a bike rack. The drop was perfect to tow my 2016 Hyundai Elantra GT

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

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.

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.

Although I just needed to shim it up to keep the wiggle down, its doing the trick with the bike rack. Still need to try it out with the camper when I head back out to work.

Have used this for a year now for my tow car and it works awesome and well built would highly recommend this to anyone needing one.
by: Gerry P07/23/2019
Just used it this past weekend for first time. It worked great! No problems whatsoever. Drove three hours to the destination and three hours back. Definitely will continue to use. I needed a hitch that was leveled with my tow bars and this was perfect. I would highly recommend etrailer for their excellent products.

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.

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!

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.

Great. Adjusted tow height and works fine.
by: Steve05/31/2016
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.
by: Greg B.01/01/2015
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.

- Adapter Needed to Tow Bruno Chariot with a 2018 Ford TransitDual hitch receivers and adapters like parts # RM-077-8 and # RM-048-8 are meant to be used for flat towing only but I do have a solution for you. The Gen-Y hitches basically give you additional receivers at varying heights and they can be used for towing and accessories. For your application we have the Gen-Y Adjustable 2-Ball Mount w/ Stacked Receivers # 325-GH-314. This fits a 2" trailer hitch and offers 7-1/2" of drop/rise. It is rated for 10K towing and 1.5K tongue weight although...
view full answer... - Which High/Low Adapter for Flat Towing Lifted JeepYou'll need a high/low adapter to bring the tow bar within 3 inches +/- of level. The adapter you need will depend on the height difference between the base plates and the receiver on the motorhome/tow vehicle. Roadmaster offers several different adapters: • For a 2 inch rise/drop, use # RM-072-2 • For a 4 inch rise/drop, use # RM-070 • For a 6 inch rise/drop, use # RM-048-6 • For a 8 inch rise/drop, use # RM-048-8 • For a 10-1/4 inch rise/drop, use # RM-048-10 I've linked to an article...

- Recommended Parts For Flat Towing a 2023 Ford Ranger XLT 4X4I completely understand your confusion Jim. As someone who has worked with all the different manufacturers over the years here are the best components which I recommend for you to use. First you will need the Roadmaster Base Plate # RM-524459-5 for your 2023 Ford Ranger. This will connect to your motorhome with the Roadmaster Nighthawk All-Terrain Tow Bar # RM-676. Do understand you may need one of the High/Low adapters from the list below as the tow bars need to be within 3" of level....

Starting with a base plate, I recommend a kit that features removable arms which will let the Spark keep more of its normal appearance when you're not towing it. Roadmaster kit # 523174-1 has such twist-lock arms that you can see in the linked photo; once you remove them the car's appearance is back to normal. The Falcon Tow Bar # RM-520 is a perfect fit with these...

view full answer... - Availability of Hitch Extension To Keep Pickup From Hitting RV When Being Flat TowedThe 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...
view full answer... - Can a Roadmaster High-Low Adapter be Used with a Kawasaki Mule for Off-the-Road TowingIf 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...

This dolly also fold up which is great when you do not have a lot of storage area. If you do not mind the additional steps while flat towing here is a list of the components you will need.

view full answer... - Can High/Low Hitch Adapter Be Used with Yakima Four Timer Hitch Bike RackHitch 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...

view full answer... - Can A High-Low Adapter Be Used With A Warn Winch?Using a high-low adapter like the Roadmaster High-Low Adapter for Tow Bars - 2" Hitches # RM-048-8 you're interested in is not recommended to be used in that capacity. The reason being is that yes you may retain the full line capacity of your winch if the winch cable remained absolutely level while being used. The reality is that your line is likely not going to stay level while being used and would result in a substantial drop in capacity. Since there is not any real way to determine...

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 need...

I prefer Roadmaster's components as their quality has shown to be better over time. You can connect this with the Roadmaster Nighthawk All-Terrain Tow Bar # RM-676. You will need to measure the height of the receiver on your tow vehicle to determine if you will need one of the High/Low adapters. When we installed the base plate on a vehicle in our shop...
view full answer... - Hitch Rise Adapter and Bike Rack for Best Ground ClearanceYes, your van's hitch would be reduced from 525 lbs to 262.5 lb when using the Roadmaster High Low Adapter part # RM-048-8 that you referenced. This would give you an additional 8 inches of rise so it would be an excellent choice. For a bike rack (if you don't have one), the Saris SuperClamp EX part # SA4025F would be an excellent choice as it has the highest rise built into the shank at 5 inches and since it's a platform rack it holds the bikes perfectly level which also helps with ground...
