  • Hitch Adapters
  • High-Low Adapter
  • Roadmaster
  • Fits 2 Inch Hitch
  • 6 Inch Rise/Drop

Make up for the height difference between your RV and towed vehicle with this hitch adapter. Provides either a 6" drop or a 6" rise. Solid shank provides strength and durability.


Features:

  • Allows for proper positioning of tow bar
    • Makes up for height difference between RV's hitch and towed vehicle's base plates
    • Also lets you mount a bike rack, cargo carrier, or other 2" hitch accessory
  • Provides either drop or rise for adequate ground clearance
  • Constructed of sturdy steel
    • Solid shank for suprerior strength and durability
  • Resists rust and corrosion with black powder coat finish
  • Hitch pin and clip or hitch lock sold separately
  • Made in the USA


Specs:

  • Application: 2" x 2" trailer hitch receivers
  • Drop/rise: 6"
  • Receiver: 2" x 2"
  • Tongue weight: 400 lbs
  • Gross towing weight: 10,000 lbs
  • Length: 14" overall
    • 3-7/8" From center of hitch pin hole to angled brace
    • 9-1/2" From center of hitch pin hole to center of pin hole
  • Limited Lifetime 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.

Make up for the height difference between your RV and towed vehicle with this hitch adapter. Provides either a 6" drop or a 6" rise. Solid shank provides strength and durability.

Simple to install and absolutely needed to keep the tow bar within 3" of the hitch height. Plus when I went over a steep driveway in my 30' Winnebago Vista, I was concerned that this may bottom out - but instead, there was a frame rail under the RV that scraped instead. This unit was well clear. If you find yourself in a situation where this could scrape the ground, it is easy just to put the brake on in the car and pull the release pin on the this unit. Then, reconnect later.



by:

Works like a charm! I bought an entire toad tow package kit wiring, breaking system tow bar, base plates everything ! My ranger all the way to Mount Rushmore last year and everything worked great! The trailer support was excellent whilst I was installing everything! Multiple calls to tech-support got me through and made for a successful install. I would not hesitate to buy From them again!



by:

Created a nice level towing setup for my 2018 Chevrolet Colorado behind my 2023 Entegra Esteem Class C motorhome.



by:

Roadmaster quality is very consistent. Drop ship from Roadmaster was fast.



by:

I needed the Roadmaster high-low adapter to drop my tow point down so my tow bar was level between my Motorhome and my Chevy Colorado. It works as advertised and even with the weight of the truck pulling on the drop of the bar it is solid enough I feel very confident that I will be able to tow for many carefree miles.



by:

Tremendous help on phone identifying the appropriate part. Delivered in two days! Great service.



by:

The 6" drop hitch was just what I needed to level my tow bar between my (Georgetown) RV and (Jeep Wrangler Unlimited Sahara) towed vehicle.

It is a very strong, solid piece. Just completed a round trip between 700 mile round-trip with no problems.

The run-through of the unit dimensions in your video really helped to ensure the unit was the right fit for my RV receiver and tow bar.

Solid chunk of metal. No problems. Need to keep areas that rub treated for rust, but thats expected.

My motorhome was to high to tow my Jeep so I needed this hitch adapter to bring the tow bar inline with my vehicle.

I sold my vehicle and purchased a new jeep and no longer utilize the adapter. I purchased a new roadmaster tow bracket from u and so far its fine.



by:

Worked great to level the tow bar out between our lifted Jeep and the RV. Very stout and glad we went with heavier duty unit



by:

Just what you need if your 4 wheel drive pickup is too high. I use it to get my wheel chair ramp close enough to the ground to use.
Very well made.

Thanks for the feedback, but did want to let you know that this adapter is intended for flat towing a vehicle only. IF you are needing a significant drop ball mount you might consider the Gen-Y line of ballmounts. For example the # 325-GH-515 might be a good option since it does provide a 10 inch drop, and may still allow you to use your existing ball mount.


by:

Works perfect for ensuring tow bar is l evel.



by:

The product works as described. There is one problem in compatibility with a Blue Ox tow bar. The pin holes in the receiver are pressed rather than drilled. This process decreases the inner receptacle size and it has to be increased by manually filing the inside of the tow bar receiver. Structurally well made.

Purchased for bike rack , I am handicapped and this adapter will lower it and make it easier to load my three wheeled bike This company is awesome to deal with Thank You

Please keep in mind that using this or any hitch adapter or extender will lower the towing and tongue weight capacity of your hitch by half.



by:

works great, it is the right drop for the toad car so it pulls level. I have seen some toads being pulled and the hitch receiver is to high so the front of the car is being pulled at an upward angle, which is not a good idea.



by:

Exactly what I needed



by:

400 pound TW. We carry two e-bikes on the back of our coach and needed to raise the bike rack. Strong and perfect fit.



by:

I installed a TorkLift Eco Hitch on the front of my F250. It sits higher than most front hitches. I need this drop receiver to lower my motorcycle below my line of sight! VERY heavy duty!



by:

I bought this drop hitch because I carry a motorcycle sideways on a rack behind my SUV. The SUV sits high so pushing the motorcycle up the ramp is difficult and lowering that rack makes loading and unloading easier and safer. The SUV also has the spare tire on the rear door and this drop hitch moves the rack out about two inches giving me more room for the bike. The big thing about this drop hitch is it’s strength. My bike weighs 350 pounds this hitch is rated at 400 pounds but it can probably handle much more than the class III hitch itself.



by:

I needed this high/low hitch receiver to bring the hitch up to level to pull my jeep behind my RV. It works excellent, very happy with it one year later!



by:

I recently purchased the 6" hitch extension from e-trailer... which fit perfect thanks to the wonderful help I received from Debora H. Without her help and all the time she spent with me on the phone I would have purchased the wrong one...again. I appreciate all her help, she saved me from another frustrating purchase and return. The hitch extension she recommended fit perfect for my application and was less expensive than the one I was originally looking at. Thank you again for your help.



by:

Received the product in excellent time. It is just what we needed and were very pleased that we could get the drop hitch made by Roadmaster as it will match the tow bar that we have on out motorhome and tow vehicle.



by:

Great product. Heavy duty, well-made. Works perfect for my custom hitch application.

Great product, functions as advertised

I had a hitch place on my 2008 Toyota Sienna. The only problem is I would have to make major adjustment to hook up my daughter wheel chair lift. Uhaul told me to search online for a high low hitch. Thank God it lead me to etrailer which had several differ kind. The pack arrive quickly and the product is outstanding. This save me at least $2000.00 worth of work. Thanks etrailer, you are the best with the lowest prices as well.



by:

etrailer has great products that you can trust. I’ve purchased from them multiple times and have always been pleased with the experience.



by:

Very good, heavy construction. Pin hole for the MH reciever should be a couple inches farther back.

    First you will want to verify with your aftermarket bumper manufacturer to ensure it is rated for flat towing use. As long as your bumper is rated for towing you can attach the 3/4" D-Ring Adapters # RM-035 to the Roadmaster Nighthawk Tow Bar # RM-676. These adapters will fit a 3/4" wide D-Ring with either a 7/8" or 1" diameter mounting pin.

I have found Roadmaster to have some of the best components for flat towing as they test more extensively than other companies.

I prefer Roadmaster as they test their products more than any other manufacturer which is why they are one of the only manufacturers which do not require you to use a safety cable around the base plate and to the frame on your Jeep. The Roadmaster Nighthawk All-Terrain Tow Bar # RM-676 is our best seller with the...

I recommend using the Roadmaster Nighthawk Tow Bar # RM-676 and the Accessory Kit # RM-9284-2 to connect your Escape. You will also need a Charge Line # RM-156-25 to prevent your battery from being drained down while towing. I do recommend using either the Air Force One # DM26VR if your motor home has actuate brakes or Stay-IN-Play...

  • High/Low Hitch Adapter with 6-Inches of Rise for Use with Hitch Cargo Carrier
    Use of a hitch adapter like Roadmaster # RM-048-6, which offers 6-inches of rise, will have the effect of reducing your hitch's capacity by 50-percent. This results from the change in geometry - the load being further away from the hitch - and is a common side-effect of hitch adapters. If you use this adapter your hitch capacity will be 250-lbs, and after you account for the 70-lb weight of the carrier you will then have an actual cargo weight capacity of 180-lbs (250 - 70 = 180).

The Stay-IN-Play DUO braking system is another excellent choice and by going that route you won't need the Stop Light Switch Kit # RM89ZR but you will still need the Relay Kit # RM-88400 to keep the brake light signal on your F-150 from overriding the turn signal from the RV when you're applying the brakes during a turn.

  • Solution for Towing Trailer Level that is 6 Inches Higher Than Tow Vehicle
    I do have a solution for you, however high-low adapters like the Roadmaster # RM-048-6 that you referenced are only designed for flat towing a vehicle. They are not suitable for towing a camper/trailer. To get the rise you need to tow your trailer level, you will instead want to look at a ball mount with around a 6 inch rise. I recommend taking a look at the Draw-Tite Ball Mount # 2793. This ball mount is compatible with 2 inch hitch receivers, features a 6-3/4 inch rise (or an 8 inch...

With that being said, If you're interested in a complete flat towing setup for your 2022 Chevrolet Traverse, you're also going to need: -A set of tow bars, like the Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar for Blue Ox Base Plates # RM-677, -A wiring kit, like the Heavy Duty Magnetic Tow Lights...

Depending on your tire size and any suspension sag over time your exact height may be different. You will need to verify the receiver height on your tow vehicle to determine if you will need a high-low adapter for the Roadmaster Falcon 2 Tow Bar # RM-520.

  • Does Hitch High-Low Adapter reduce both vehicle and hitch tongue weight?
    When using a high-low adapter like # RM-048-6 with a cargo carrier, the hitch receiver tongue weight only is cut in half (reduced by 50%). For instance if your hitch is rated for 350 lbs tongue weight, then you would reduce that to 175 lbs and also subtract the weight of your cargo carrier. That would give you the carrying capacity of your combined components.

    Demco has confirmed that their Commander Tow Bar part # DM9511012 does work with the Tabless base plate kits like the part # DM9519339 that fits your 2018 Jeep Wrangler JL. Sometimes tow bar heights and base plate heights don't line up perfectly. That is why companies like Roadmaster created high low adapters like the # RM-048-6 which can give a 6 inch rise or drop.

With these mounts you will not need to use a crossbar and will be able to connect directly to the Roadmaster BlackHawk 2 All Terrain, Non-Binding Tow Bar # RM-422.

  • What is Best High Low Adapter to Use When Tow Bar Setup Calls for 7 inches of Drop
    Based on your dimensions you'd need 7 inches for your tow bar to be totally level. So since there's only a 6 inch and an 8 inch high low adapter the better choice is to have the sitting slightly higher on the RV side. If a tow bar pulling down on the vehicle front suspension it can cause tire wear issues as well as suspension issues so slightly higher on the RV side is best. So the 6 inch # RM-048-6 is the best option.

  • High Low Adapter for a Vehicle Hitch that Sits 5 inches Higher than Level
    I would go with the 6 inch Roadmaster High-Low Adapter part # RM-048-6. Being an inch off either way would not be a big deal, but I would rather have your tow vehicle pulling slightly up than down as down usually wears tires and suspension components on towed vehicles.

  • High Low Hitch Adapter that Can Carry Motorcycle Carrier
    We have the similar high low adapter that can be used with a hitch carrier like what you have with the part # RM-048-6 but the Blue Ox you mentioned can only be used with flat towing. Adapters like this do cut the capacity of the hitch in half when used due to added length and movement.

The Roadmaster Dual Hitch Receiver Adapter, 6" Drop/Rise # RM-077-6 is the strongest option with a 400 lb tongue weight capacity that doesn't account for the weight of the carrier, so is not a working option. Adapters simply are not strong enough for the tongue weight you are seeking. Your best option is to use the Replacement Shank for Gen-Y Adjustable Ball Mount - 2" Hitch - 7-1/2" Drop/Rise...
