Always willing to help and always ship fast!



by:

Product has worked well after 8000 miles of usage.



by:

These were exactly what I needed. I changed tow vehicles to a Honda HRV (manual) and the only base plate available was the Roadmaster. These adapters took about 10 minutes to change my Blue Ox tow bar to accept the Roadmaster.



by:

Needed this adapter to connect my blue ox tow bar to the roadmaster base plate on the car. The adapter was in stock and shipped quickly to meet my needs.



by:

All the products I ordered from etrailer,fit and worked excellent for me to be able to flat tow my 2015 Chevrolet Colorado behind our motorhome. I live in Canada and fast delivery on the products I ordered. I will order from etrailer again



by:

Dealing with etrailer was good experience that includes timely, good prices, good salesperson and great installation. Thanks, when I need something else etrailer will be my first choice. I tell everyone to go to etrailer but most have never of etrailer.



by:

Great product. Worked perfect. Didn't realize that it didn't come with the pins (my fault) and the pins I had were too small. Had to order correct pins and pay additional shipping. The correct pins are 3/4" diameter so if yours are smaller than that, order the right ones with the kit to avoid additional shipping charges.....just FYI.



by:

This product saved me time and money by not having to make an adaptor from my Blue Ox tow bar to Roadmaster base.



by:

I called, and got the right information. Later on that day I ordered online and everything came on time.
The mount, and the wiring kit fit exactly as expected.
I bought several items over the years and I highly recommend etrailer.



by:

I JUST GOT HOME AND FOUND MY ORDER FROM ETRAILER WAITING FOR ME ON MY PORCH. I have not as of yet tried to install it, but everything I will need for installation was included. I will comment later on as to how the installation went. Thank you etrailer for your fast response and delivery.



by:

Etrailer originally told me that they could not help me with an adapter I needed. They did not give up the following day Bob the shop supervisor called me and said he had taken another look and had figured out what I needed. They shipped the part the same day.
Great service. I will be a repeat customer.

  • Do You Have a Roadmaster Base Plate for My 2025 Ford Ranger?
    Hello Russell, Great question. The Blue Ox Base Plate Kit - Removable Arms # BLU77XR fits the 2019-2023 For Ranger. For the 2025 Ford Ranger we only have the Roadmaster Direct-Connect Base Plate Kit # RM23DQ at this time which is a pre-order item. The delivery date might not be completely accurate since Roadmaster is still in the works on designing one. I am sure Blue Ox is in the works for one as well as the Ford Ranger is a popular vehicle to flat tow. If the Roadmaster Base Plate...

  • Flat Towing a 2021 Ford Ranger With Adaptive Cruise Control
    Yes, the Blue Ox Base Plate Kit for a 2021 Ford Ranger is part number BX2689 and this is listed on the etrailer site under, # BLU77XR. It is a confirmed fit for all models/trim levels of the 2021 Ford Ranger and includes models with ACC - Adaptive Cruise Control. To flat-tow a 2021 Ford Ranger you need at minimum, base plates, safety cables, tow bar, a wiring solution for indicator lights, and supplemental braking that is required by law.

  • Is Blue Ox Tow Bar Compatible With Other Brand Base Plates on 2005 Ford F-250
    You do not have to use the Blue Ox Base Plate Kit # BX2177 on your 2005 Ford F-250 if you don't want to. However, you will need an adapter to use a Blue Ox tow bar with a different base plate brand. For example, if you would rather use the Roadmaster Direct-Connect Base Plate Kit # 4403-1 with removable arms all you need is the Blue Ox Tow Bar to Roadmaster EZ5, MS, and MX Base Plates Adapter Brackets # BX88185.

  • Can Vehicle with Roadmaster Base Plate Connect to Blue Ox Tow Bar
    We do have an adapter that will allow you to connect your Blue Ox tow bar to your Roadmaster base plate kit with the # RM-032 for if your base plate requires a crossbar or part # BX88185 if you have the direct connect style of base plate kits. If your base plates look like the picture I attached you'd need the # RM-032 as that's the crossbar style.

  • Will Demco Base Plate Fit 2026 For Maverick Hybrid Lariat
    Hey Bob! We are ahead of manufacturer fitment pretty often, and have confirmed that the Demco Tabless Base Plate Kit # DM38CV will fit the 2026 Maverick Hybrid. Our own etrailer Invisible Base Plate Kit # e96GV shares the same design so you can use that as well. It will work with a Demco tow bar if you already have one, and etrailer tow bars like the SD # e34ZR and XHD # e94ZR. If you would prefer manufacturer confirmation, then I recommend the Roadmaster Direct-Connect Base Plate Kit...

  • How To Use a Blue Ox Tow Bar with Roadmaster Base Plate Kit
    It is super easy to attach a Blue Ox Tow Bar to a Roadmaster Base Plate Kit. If you have the Roadmaster Crossbar-Style Base Plate Kit like part # 1555-5 then you will need to use the Blue Ox Tow Bar to Roadmaster Base Plates Adapter part # BX88178 but if you have the Roadmaster Direct-Connect Base Plate Kit like part # 1555-3 then you will need to use the Blue Ox Tow Bar to Roadmaster Base Plates Adapter part # BX88185.

  • Recommended Base Plate for 2024 Ford Maverick With a Blue Ox Base Plate That's Too Wide
    Okay Bob, so I did a bit of digging around and apparently this is a known issue that Blue Ox is aware of. The 41" distance between the mounting points is too wide and non-standard which is why your tow bars are being stretched too far. Unfortunately there is no solution from Blue Ox which is a bit disappointing but with that said you'd be better off getting rid of those base plates and use something else instead. That much stress on your tow bar/base plates is going to only end up bad...

  • Parts Needed to Flat Tow a 2020 Buick Envision
    I can definitely help you out with a flat towing setup for your 2020 Buick Envision! You can definitely use the Roadmaster Crossbar-Style Base Plate Kit # 523196-4 with the Adapter # RM-033 so that the base plate kit is compatible with a Blue Ox tow bar, but in all honesty it would be much easier to use the Roadmaster Direct-Connect Base Plate Kit # RM-523196-5 with the Adapter Kit # BX88185 instead because you don't have a whole bar that you need to use as an adapter. I'm guessing that...

  • Will the 2005 Honda Elements Frame Need to Modified to Install the Roadmaster MX Base Plates
    The Roadmaster MX Base Plates # 1541-5 that are confirmed to fit your 2005 Honda Element does not require you to cut or alter any of the steel frame of your vehicle. The base plates will bolt to the vehicle using existing holes. The only modification will be needed will be on the bumper fascia to allow the tow arms to connect to the base plates. For your Blue Ox tow bar, I recommend the Blue Ox Tow Bar to Roadmaster EZ5, MS, and MX Base Plate Adapter Brackets, # BX88185. This adapter...

  • Which Base Plate Adapter for Blue Ox Tow Bar and Roadmaster or Demco Baseplates on 2021 Jeep JLU
    In order to make Roadmaster or Demco base plates like the # RM-521453-4, # RM-521453-5 or # DM9519336 work with a Blue Ox tow bar you will need adapters that depend on the specific tow bar and base plate combination. The # RM-521453-4 can use either # RM-032 or # BX88178 to make it compatible with most Blue Ox tow bars. The # RM-521453-5 uses the # BX88185 to make it compatible with the same Blue Ox tow bars. The # DM9519336 is a tabless baseplate, so you'll want to use the # DM9523127...

  • Difference in Tow Bar Wiring Kits for 2017 Ford Explorer
    I'm glad to hear that you are doing your research when it comes to flat towing your 2017 Ford Explorer, there are several components needed and it can be a lot to figure out. The main difference between Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 and the Tow Ready Tail Light Isolating Diode System with 4-Pole Connector # TR118821 is how they install, and what is included. The # RM-15267 kit comes with 4 separate diodes, 27' of wire, connectors, a 6 way plug to mount...

    Hi John! We have the Blue Ox Base Plate Kit - Removable Arms # BX1139 for your 2025 Jeep Wrangler Unlimited JL, but it will install the same way as the one on your '08 model (see first included picture). The only way to get away from that would be if you had the off-road bumper that had D-Rings ( # BX88357 for 7/8" or # BX88358 for 1"). The # BX1139 does also include attachment points for the wiring plug and a break away switch, so I guess there is that. If you don't mind going with...
