Roadmaster Accessories and Parts - RM-048-8

  • Tow Bar
  • Hitch Adapters
  • High-Low Adapter
  • Roadmaster
  • Fits 2 Inch Hitch
  • 8 Inch Rise/Drop

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.


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: 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
  • Limited Lifetime Warranty


Dimension between hitch pin holes is 10.5 inches measured in red

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.

  • High-Low Adapter for 2008 Country Coach Magna Motorhome Towing Mini Cooper S
    Thank you for providing that information. Also, sorry you never heard back from your original question. With your receiver at 22" and a base plate height of 14-1/2" you need the Roadmaster High-Low Adapter for Tow Bars # RM-048-8. This has a drop of 8" putting you right in the middle of the safe zone which ranges from 3" above level to 3" below level.

  • Can 2018 Chevy Sonic with Automatic Transmission be Flat Towed Behind Motorhome
    Yes a 2018 Chevy Sonic with an automatic transmission can be flat towed behind a motorhome and we have the parts needed to do this. The first thing you'll need is a base plate kit confirmed as a fit for your vehicle with the Roadmaster # RM-523194-5. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon All Terain, # RM-522. This has non-binding...

  • 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.

  • Parts Needed To Flat Tow a 2017 Jeep Wrangler Lifted With Aftermarket Bumper Having 3/4" Wide D-Ring
    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. With your 2017 Jeep Wrangler being lifted you will likely need one of the High-Low adapters to keep the tow bars within 3" of level from your motorhome...

  • Parts Needed To Flat Tow a 2023 Jeep Wrangler Rubicon With a 2020 Forest River Sunseeker
    Actually, you came to the correct place as this is what we do best. To start you are going to need a base plate of which I recommend using the Roadmaster # RM-521453-5. I have found Roadmaster to have some of the best components for flat towing as they test more extensively than other companies. The Roadmaster Nighthawk All-Terrain Tow Bar # RM-676 will allow you to connect your 2023 Jeep Wrangler Rubicon to your 2020 Forest River Sunseeker 2500TS. You may need one of the adapters from...

  • Parts Needed To Flat Tow a 2024 Ford Escape
    Since the 2024 Ford Escape is unchanged from the 2023 I see no reason you would not be able to use the Roadmaster Base Plate # RM77GR on the Hybrid trims. 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...

    For the safest and easiest setup you will need the Roadmaster Base Plate # RM-521448-5 for your 2013 Jeep Wrangler Sport. This will connect to your 2008 Forest River Sunseeker with the Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar # RM-676. These bars have an aluminum construction for light weight along with lights for better visibility and channels to hold the cables.

  • Recommended Parts For Flat Towing a 2013 Jeep Wrangler Unlimited
    I see you were looking at base plates. For your 2013 Jeep Wrangler Unlimited I recommend the Roadmaster Direct-Connect Base Plate Kit # RM-521448-5. Roadmaster has always made a quality product and this will allow you to easily connect to your tow vehicle using the Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar # RM-676. You may need one of their High/Low adapters to level your tow bars as they need to mount within 3" of level from your tow vehicle to your Jeep. Here is a list of...

  • Will The 2-Piece Roadmaster Base Plate Kit # RM-521453-5 Fit a 2016 Jeep Wrangler Unlimited?
    For your 2016 Jeep Wrangler Unlimited you are going to need the Roadmaster Direct-Connect Base Plate Kit # RM-521448-5. The crossbar integrated into this mount is required due to your chassis. On the newer JL Wrangles the Base Plate # RM-521453-5 you found is designed to fit the chassis has more strength and does not need the crossbar. I recommend pairing this with the Roadmaster Nighthawk # RM-676. The Roadmaster Accessory Kit # RM-9284-2, Wiring # HM56200, and Charge Line # RM-156-25...

  • Can a 2015 Chevrolet Sonic LTZ With Automatic Transmission Be Flat Towed?
    While your 2015 Chevrolet Sonic LTZ with an automatic transmission can be flat towed I would recommend using a Dolly # DM9713045 since you are required to stop and run the engine when towing(see owners manual) for extended periods of times. 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.

  • Recommended High Low Adapter for a Yakima Stagetwo Bike Rack
    If you've already got an extension that pushes the rack out to clear your spare tire you aren't going to be able to add a second adapter. We don't recommend using two hitch adapters at the same time because not only does it reduce the weight capacity of the hitch even more (more than the 50% from using one adapter), it can also be dangerous for other motorists. I'd recommend just using a taller high low adapter like the Roadmaster High-Low Adapter for Tow Bars # RM-048-8 which has 8"...

  • Parts Needed For Flat Towing a 2015 Jeep Wrangler JK With Nilight Aftermarket Front Bumper
    I tried reaching out to Nilight to both verify their front bumper for your 2015 Jeep Wrangler JK is both safe for flat towing and the dimensions of the tabs. They could not provide me with either so you will want to first verify if your bumper is safe for flat towing and the dimensions of the mounting tabs. We have the 1" Wide # RM-035-1 and 3/4" Wide # RM-035 adapters which are designed to replace the ends on the Roadmaster tow bars like the Nighthawk # RM-676. Both the adapters above...

  • Recommended Flat Towing Solution For 2022 Ford Bronco With Modular Bumper and Winch
    I do see the winch and mount you found is for attaching to the Ford Modular bumper on your 2022 Bronco. For this I recommend the Roadmaster Direct-Connect Base Plate Kit # RM92ZR. Roadmaster has one of the best reputations for quality and testing among all the brands we carry. Here is a list of the other components that will be required for flat towing your Bronco.

  • 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 that...

  • 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...

  • Parts Needed To Flat Tow a 2023 Ford Ranger Behind An RV Motorhome
    I recommend using the Roadmaster Direct-Connect Base Plate Kit # RM-524459-5 on your 2023 Ford Ranger. This base plate uses removable arms so when you are not towing you will still maintain a clean appearance on the front of your Ranger. The Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar # RM-676 is the tow bar I recommend using. This tow bar has integrated lights on the bars which will help with hooking up and disconnecting when it is dark. The Roadmaster Accessory Kit for Nighthawk...

  • Hitch Adapter to Raise Height of Cargo Carrier for Batter Ground Clearance
    We can help you with a 2-inch hitch adapter that will give you a height rise for better ground clearance with your CargoPod hitch cargo carrier. I suggest the Roadmaster 2-inch High-Low Adapter # RM-048-8. The Roadmaster has a solid steel shank for strength rather than a hollow one like the Malone # MPG544 and it gives you a full 8-inches of rise. This too will reduce your hitch's rated capacity by 50-percent, the same as the Malone, and it also shares the same 400-lb tongue weight (TW)...

  • Hitch Adapter and Bike Rack Recommendation for E-Bike and Flat Towing
    To replace your Roadmaster High-Low Adapter # RM-048-8 I recommend using this replacement shank from Gen-Y: - Replacement Shank for Gen-Y Adjustable Ball Mount # 325-GH-404 I like this option because it's more heavy-duty than pretty much every other adapter, plus it has a receiver above the shank so your bike rack will be at a higher location for better clearance. Then for a bike rack I recommend using the Swagman E-Spec # S94FR and then using the Swagman Ramp and Bridge # S32YR to...

  • Which High/Low Adapter for Flat Towing Lifted Jeep
    You'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...

  • 8 inch High Low Adapter Solution that Can Fit 2-1/2 inch Hitch Size
    We used to carry that adapter but Roadmaster stopped offering it to us. Best solution would be the version that fits a 2 inch hitch part # RM-048-8 with a 2 inch to 2-1/2 inch adapter part # C45405.

  • 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...
