Insert this heavy-duty drop hitch receiver adapter into your 2" hitch to get up to an 4" rise or drop for high or low ground clearance.


Received wrong item initially however Kate made things happen and received correct item the following day. Greatly appreciate.


First of all, the folks at E-Trailer could not have more more pleasant to deal with as usual. I have not used the Adapter yet but it appears to be exactly what I needed to complete my flat tow project, while addressing my other trailers. I was a little surprised at the rough finish of the steel pieces. Reminds me of "Made in CHINA" steel products.


Exact fit for my rv


Perfect fit


The Hitch Receiver Adapter worked great .


Fast delivery, but one of the pin clips was missing. I called and a new clip is being sent . Great service!!


Exactly what I was looking for

  • Do I Go By Hitch Receiver or Ball Mount Tongue Weight Rating To Be Safe
    Great question! You always need to stick with the lowest rated component so even though the Blue Ox Adjustable Drop Hitch Receiver Adapter # BLU34TR has a 1,000 lb weight capacity you'll be limited by the 350 lbs of your hitch receiver tongue weight rating. Attached is a review video for you to check out.

  • Typical Professional Installation Time for Blue Ox Base Plate Kit # BX3788 on 2015 Toyota Corolla
    I am not trying to avoid directly answering your question but the exact amount of time needed to complete a base plate installation on a vehicle can vary quite a bit. The particular equipment on a vehicle, the installer's experience and even the nature of the equipment in the shop can have an effect on the time required. Even with a well-qualified shop and technician, if it is the first time a particular base plate kit has been installed on a particular car, it will take longer than if...

  • 4 inch High Low Adapter for Use with Commander 2 Tow Bar
    It would seem that the Demco High Low Adapter would work fine with your Commander but since they specifically said that it only fits the Victory Series tow bars since that's only tow bar that tested it for we have to recommend you follow that, but we can still help. We have the Blue Ox High Low Adapter part # BX88129 which provides 4 inches of rise/drop and can be used with any tow bar including your Commander 2.

  • Recommended 4" High Towing Adapter for Flat Towing
    I recommend the Roadmaster High-Low Adapter for Tow Bars item # RM-048-4. This high low adapter will provide a 4" drop. To be considered level the tow bar needs to be within 3" of your base plates.

  • Items Needed to Flat Tow 2013 Chevrolet Silverado 1500 Behind Class C Motorhome
    We can help. Safe and legal flat towing requires a few items, including a tow bar, safety cables, a wiring/lighting kit of some kind and a braking system and base plates on the towed vehicle. Also a high/low hitch adapter often comes into play too, which can help you get the tow bar close to level (important for good performance). You can refer to the linked articles on flat towing for more on each of these items. Let's start with base plates for the 1500. I recommend the Blue Ox kit...

  • Can a 2002 Volkswagen Passat Wagon with Manual Transmission be Flat Towed
    When it comes to flat towing a vehicle the car owner's manual is the best resource for determining if it can be flat towed at all and what preparations steps, if any, are required to ready the car for this kind of transport. In general, cars with a manual transmission are often easier to equip for flat towing than cars with an automatic transmission. I reviewed an online edition of the owner's manual for the 2002 Volkswagen Passat wagon but it did not confirm if the car can be flat towed....

  • Is Hitch Extender Needed With Blue Ox BX8870 KarGard Towed Vehicle Protector
    According to Blue Ox, users of the Blue Ox # BX8870 KarGard typically don't need an extender to increase the distance between the motorhome and the towed vehicle because the KarGard will sit pretty close to the vehicle being towed (about 1 foot). If you should find you need an extender, Blue Ox tells me that it's acceptable to use the # BX88264 for 12 inches of extension or # BX88265 for 6 inches of extension, but the tow bar will need to be within 3 inches of level. They go on to say...

  • Parts Needed to Flat Tow 1999 GMC Denali
    A complete flat towing setup consists of base plates, a compatible tow bar, safety cables, tow bar wiring, supplemental braking and potentially a high/low adapter. I recommend starting with the Roadmaster MX Base Plate Kit # 3101-1 and the etrailer SD Non-Binding Tow Bar for Roadmaster Direct-Connect Base Plate - 2" RV Mount # e74ZR. This tow bar comes with safety cables integrated and the non-binding design helps make hookup and release easier when you're on un-even ground. The Roadmaster...

  • Parts Needed to Flat Tow 2014 Ford F-250 Behind Class A Motorhome
    Flat towing a vehicle behind a motorhome requires a number of components in order to be safe and legally compliant in all states. Those items are detailed in the linked article and include a tow bar, safety cables, a wiring/lighting kit, sometimes a wiring extension and high/low hitch adapter, and also a set of base plates and a braking system for the toad. I recommend Blue Ox base plates # BX2618 along with the Alpha tow bar # BX7380 since these work together without adapters and the...

  • Hitch High-Low Extender Adapter for Use With Anti-Rattle Pin That Bolts in
    By receiver end I take it that you mean the solid shank end of the Roadmaster High-Low Adapter # RM-048-4 that fits in the trailer hitch receiver on your motorhome. If this is the case then the Curt Hitch Extender # C45791 is designed the exact same way. For a 4" drop/rise adapter that has a hollow shank you can use an anti-rattle device like part # 63232 we have the High-Low Adapter # BLU34TR. This allows you to insert the block from the anti-rattle pin to help keep this from moving in...

  • Recommended Parts to Dinghy Tow a 2017 Chevrolet Sonic LT Sedan
    I have the perfect setup to dinghy tow your 2017 Chevrolet Sonic LT. For a tow bar I recommend using the Blue Ox Base Plate Kit, part # BX1703. This kit does not require any welding and has base plate tabs that can be removed for a very clean look when you are not towing your Sonic. The next thing that you will need is a tow bar. I really like the Blue Ox Alpha, part # BX7380, for this setup because it works well with the base plate kit and it comes with safety cables. This tow bar it...

  • Flat Towing Setup for 2018 Chevy Equinox 1.5L FWD
    I checked the owner's manual for the 2018 Chevy Equinox FWD 1.5L and this car can be flat towed. Like other towable cars there is a preparation process to be followed before each trip and this is covered on page 359 of the online manual. For the labor cost alone for installing a complete flat towing setup you can figure $2000 as a "ballpark" starting point. This is labor only and is in addition to the parts' cost. The labor fee will vary depending on whether you select a non-labor-intensive...

  • How To Use etrailer Tow Bar on a 2020 Jeep Wrangler

  • 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 Base...
