Note: Designed for flat towing only. Do not use to tow a trailer.

Many tow systems require some sort of hitch accessory to either raise or lower your tow bar so that it sits level. To determine if your setup needs an adapter, hook the tow bar up to your RV and towed car and measure to see how close to level it is. The "safe zone" for a motor-home-mounted tow bar ranges from 3 inches above level to 3 inches 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.

Just what we where looking for. Great p roduct! 804829

Very sturdy, had an additional hole drilled so I could position it closer to the vehicle. 727742

Just received my order earlier than expected. Have not installed it yet but it appears to be just what I needed to connect my new Ford Ranger to the back of my RV. My previous tow vehicle had a 4 inch drop so by doing some measurements I'm sure the 2 inch will work as required to level the tow bar. Thanks again for exceeding my expectations. 718442

Drop hitch has worked well and provides the adjustment needed to get out towbar more level. It has withstood the weather and substances that it encounters and still looks new. I would recommend this product if you are in the market for a drop hitch to make your towbar be more level when attached to your motorhome. 710621

High quality, fast delivery, excellent customer service. Knowledgeable staff worked with me on shipping and follow up. etrailer has highest quality products and combined with their employees, provide the very best service I have ever found. Some places may be a little less expensive but it’s not worth the minimal savings when compared to the known quality, excellent service, and delivery and follow up that etrailer always provides. 663447

Just installed a towbar for 4 down towing, and needed to drop 2" to level the bar in relationship to the towed car. However, I have a sloping driveway to the street and have to worry about scraping. BlueOX made the shortest extension (8"), which gave me the 2" drop I needed. I did some calculations and measurements, and I figured that it should JUST work. Received the extension today, put in on the coach before installing the towbar and made a test run. I have exactly 1" to spare before the hitch would scrape. Just a perfect fit for what I needed. 620228

What can you say about a hitch receiver. It's well made, heavy and I'm sure a durable. I needed 2" drop for the Jeep Wrangler I am towing. Had an 8" drop receiver prior for a low slung VW Bug and on steep driveways it would drag. As always etrailer was quick to fill the order and it arrived within a few days of the order. Good price and free shipping. 590208

As good as day one.

Customer service was exceptional. Megan went out of her way to help us and discovered we were ordering a part that could potentially cause us trouble down the road. Thanks for the extra effort! 282845

Excellent service at a good price. Totally professional in all respect. Required lowering the hitch ball on my 2016 Yukon. The heavy duty two inch Blue Ox drop receiver will do the job. 258316

I have a Blue Ox tow bar attached to 3/4 ton pickup with a truck camper in the truck bed. I use this for towing a Jeep. Blue Ox wants the tow bar to be level, but I had between a 2" and 3" drop from the Jeep to the pickup truck. This product raised the tow bar up 2" at the pickup truck and the tow bar is now nearly level. In addition, it moves the pivot point 6-1/2" to the rear, which allows me to make sharper turns without worrying about the Jeep hitting the camper. This product did an excellent job of solving my problem. 172844

Ask the Experts about this Blue Ox Accessories and Parts

  • What is the Tongue Weight Rating for the Blue Ox High-Low Adapter BX88128
    In most cases whenever you use an adapter you will be cutting your Tongue Weight (TW) capacity in half. So if the trailer hitch receiver on your Ford F-150 has a TW of something like 900 lbs then an adapter will make your TW 450 lbs instead. I contacted Blue Ox and they were unable to supply me with a TW rating for their High-Low Adapter # BX88128 so it would be safest to just cut your TW rating in half. Now in the case of the Roadmaster High-Low Adapter # RM-048-2, if your TW was...

  • Option for Hitch Adapter that Raises Cargo Carrier Height
    The only product that is designed for what you are looking to do is actually the part # D210 which will have a second hitch opening that is about 3-1/2 inches above the shank that slides into hitch tube. The BX88128 cannot be used with cargo carriers like the # C18152.

  • How to Pick Out Drop Ball Mount to Allow Trailer to be Towed Level
    What you need is a ball mount with 2 inches more drop than what you currently have. Using a drop adapter like the part # BX88128 is not the best solution as this adds quite a bit of length and movement to the towing setup which cuts the capacity of the hitch down by 50 percent. I attached an FAQ that details how to pick out the correct ball mount. Picking out the correct ball mount will allow your trailer to sit as level as possible. Basically you will first measure the height from the...

  • Tow Bar for Blue Ox Base Plate BX1131 on 2011 Jeep Liberty Renegade
    According to Blue Ox, the Blue Ox Base Plate Kit # BX1131 is only compatible with motorhome-mounted tow bars, so it will not work with your BX4212 car-mounted tow bar. We do have tow bars which will work, and for that I recommend the etrailer SD Non-Binding Tow Bar for Blue Ox Base Plates # e47ZR. This is a great value for a tow bar that has long arms for maneuverability and also has safety chains so you don't have to purchase those separately. Along with Tow Bar # e47ZR and Blue Ox...

  • Will Blue Ox Base Plate Fit 2016 Jeep Wrangler Unlimited Factory Bumper With Winch
    The Blue Ox Base Plate Kit # BX1126 may be able to work on your 2016 Jeep Wrangler Unlimited with the factory bumper and a winch, so long as you are sure that the winch does not have any interference with the frame where the base plates install, which is on the outside like you mentioned. You also need to ensure the other aspects of the install do not interfere, which it sounds like you have done. We can't guarantee a fit, of course, so be sure to double check the instructions and installation...

  • How to Pick Out Correct Rise/Drop High Low Adapter for Flat Towing Vehicle
    If you check out the picture I attached you can see that when picking out a high low adapter for a flat towing setup you need to have the tow bar sit within 3 inches of level to be "safe." Otherwise suspension and tire damage might occur. First thing you need to do is measure from the ground to the top of your hitch opening on your tow vehicle and then measure from the ground to the center of your base plate kit on your towed vehicle. The difference in these two figures is the amount...

  • Hitch Extender for Swagman XTC2 With a Drop For Spare Tire and Tailgate Function
    For your Swagman XTC-2 # S64670 you can use the Curt Dual 2" Receiver Tube Adapter, 8" Extension # D-192 and simply invert it so the bike carrier tube is lower than the receiver tube. This will move your bike rack down about 5-1/4 inches and extend it 8 inches to give you spare tire clearance. This adapter will decrease your hitches tongue weight capacity by 50% but that shouldn't be an issue with a 2 bike carrier on a Jeep. If you want a 2 inch drop, you can use the Roadmaster High-Low...

  • Does Blue Ox Base Plate for 2005 Hummer H2 Just Replace Tow Hooks
    Yes, you are correct; your 2005 Hummer H2 will not have a large plate on the frame when installing the Blue Ox Base Plate Kit # BX4102. I have added a link to the instructions which detail this, but essentially these base plates are simply going to replace your existing tow hooks, like you mentioned. There are a number of other parts you'll need to flat tow your 2005 Hummer H2, and I'll recommend the parts you need. - Tow Bar: Blue Ox Avail Tow Bar # BX7420 - Wiring Kit: Roadmaster...
