Ask the Experts about this Blue Ox Tow Bar

  • Blue Ox Parts Needed to Flat Tow a 2019 Ford Ranger 4x4
    The Blue Ox Ascent part # BX4370 is a great choice for a tow bar to flat tow your 2019 Ford Ranger with the base plate kit # BX2679. The cover part # BX88309 is the correct one for this tow bar as well. For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. This comes with a round 6-way connector that...

  • Parts Needed for Flat Towing 2020 Jeep Wrangler Unlimited Rubican with Steel Bumper
    I'll start off by saying, it looks like you've got a pretty good idea of what you're looking for-which is great. However, since you have a Blue Ox Ascent # BX4370, I recommend instead going with the Roadmaster EZ5 Baseplates # RM-521453-5 which require the Blue Ox # BX88185 adapter. The reason for this is that the Ascent tow bars use a slightly different adapter connection and this is the only base plate I can confirm, with certainty, will work with your Ascent tow bar. You also may need...

  • Comparing Roadmaster Nighthawk and Blue Ox Ascent for Flat Towing 2020 Chevy Equinox
    The Blue Ox Ascent # BX4370 and the Roadmaster Nighthawk part # RM-676 are both very nice tow bars with many of the same features. both will work great but from using both Roadmaster and Blue Ox flat towing components I think the Blue Ox setups are a bit easier to use. The Nighthawk does have LEDs in the outer arms but that's only real distinct feature difference. For your 2020 Chevy Equinox the correct base plate kit is the # BX1730. The DUO part # SM99251 is the easiest install and...

  • Why Does My Blue Ox Ascent Tow Bar Need To Be Level
    The reason for this comes down to safety and the additional pressures that would be exerted on the components when your Blue Ox Ascent # BX4370 tow bar is not level. The additional force that is put on these components ultimately makes it more likely that there is a catastrophic malfunction while towing your vehicle. I'll also add that while you may not see much binding currently since you're on a flat surface, it's more likely to happen over time with maneuvering around corners and up...

  • Blue Ox Ascent Tow Bar Measurements Retracted and Extended
    The Blue Ox Ascent Tow Bar - Motorhome Mount - 2" Hitch - 7,500 lbs # BX4370 has arms 2 inches longer than most. I reached out to my tech contact who said when the legs are in it is 44” from receiver pin to holes on triple lug. When fully extended 54”. This is with the legs closed together. That distance will be shorter when the legs are spread and attached to a baseplate because expanding will created an angle to reduce the distance between connection points without changing the arm length.

  • Does Blue Ox Ascent Tow Bar Work With Blue Ox Base Plates for 2020 GMC Canyon 4WD
    I spoke with Blue Ox and confirmed that your Blue Ox Ascent Tow Bar # BX4370 is compatible with the Blue Ox Base Plate Kit # BX1721 that fits your 2020 GMC Canyon with 4WD. These are two of the parts you will need in order to flat tow your 2020 Canyon, and to make it easy for you to order everything, I'll list out all of the parts required. - Base Plate Kit: Blue Ox Base Plate Kit # BX1721 - Tow Bar: Blue Ox Ascent Tow Bar # BX4370 - Wiring Kit: Roadmaster Diode 7-Wire to 6-Wire...

  • Flat Tow Parts For 2019 GMC Acadia
    I looked up the owners manual for you 2019 GMC Acadia and it says that both FWD and AWD models with the 3.6L V6 can be towed with all 4 wheels on the ground. If you have the 2.4L L4 it states that it is not designed to be towed with all 4 wheels on the ground. I recommend that you verify what the owners manual states and verify how your Acadia is equipped. The manual will also outline the procedure of how to put your Acadia into tow mode before your trip. To flat tow your Acadia there...

  • Recommended Tow Bar Wiring Kit for 2010 Jeep Wrangler Unlimieted
    There is not a specific wiring kit for your Blue Ox Tow Bar # BX4370. Blue Ox doesn't have a wiring harness specifically for your vehicle, so I recommend the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56200 which is a custom fit for your 2010 Jeep Wrangler Unlimited factory wiring. It makes it just plug and play after running the wires from the front of the vehicle to the rear tail lights.

  • Will Blue Ox Tow Bar Work With Roadmaster Base Plates On 2015 Jeep Wrangler Unlimited
    The Blue Ox Ascent Tow Bar part # BX4370 will work on a 2015 Jeep Wrangler Unlimited using the Roadmaster Direct-Connect Base Plate Kit part # RM-521448-5 but you will need the Blue Ox Tow Bar to Roadmaster EZ5, MS, and MX Base Plates Adapter Brackets part # BX88185. This adapter is very seamless and would be pretty much the same as using a matching tow bar and base plate kit.There would not be any sort of crossbar required for installation.

  • Compatibility of Blue Ox BX4370 Ascent Tow Bar with 2015 Ford F150
    From what I've found, the 2015 Ford F150 will weigh between 4000 and 5000 lbs, depending on cab configuration and bed length. Since the # BX4370 Blue Ox Ascent tow bar is rated up to 7500 lbs, it'll work just great for you. You'll need a few other items to complete your flat towing system if you haven't chosen them already. You'll need base plates, a wiring solution, a supplemental braking system and possibly a high/low adapter. For base plates, I'd recommend the Blue Ox # BX2671....

  • Recommended Flat Towing Setup for 2019 Jeep Cherokee
    For your 2019 Jeep Cherokee, I recommend using the Blue Ox Base Plate Kit - Removable Arms # BX1141 which is a fit as long as you have the 2 speed transfer case and do not have the active air shutters. Then you can use the Blue Ox Avail Tow Bar - Motorhome Mount - 10,000 lbs # BX7420 or the Blue Ox Ascent Tow Bar - Motorhome Mount - 2" Hitch - 7,500 lbs # BX4370 which you asked from. The Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 will use your factory wiring...

  • 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...

  • Is Blue Ox Ascent Tow Bar Compatible With Blue Ox Off-Road Bumper Adapter

  • Parts Needed for Flat Towing 2014 Jeep Wrangler Unlimited with AEV Front Bumper
    You are on the right track for flat towing your 2014 Jeep Wrangler Unlimited with the AEV bumper. The base plate kit part # BX1133 is the correct fit and the Ascent Tow Bar part # BX4370 would work well with this. For lighting the part # RM-15267 is a great choice but instead of the Invisi Brake I would recommend the Demco DUO part # SM99251 as it installs easier and is a more effective braking solution. Your application would not require a brake light relay either.

  • Will the Demco Sentry Deflector Adapter Kit Work With Blue Ox Ascent Tow Bar
    I do have an option but the Demco Sentry Deflector Adapter Kit part # DM9523061 won't work with the Blue Ox Ascent Tow Bar part # BX4370 because the Ascent uses a larger shaft. Therefore, you would instead need to use the Blue Ox KarGard Towed Vehicle Protector part # BX8870.

  • Base Plates and Accessories for Flat Towing 2018 Subaru WRX
    The Blue Ox # BX3620 is indeed the correct base plate kit for your 2018 Subaru WRX. In addition to the base plates, you'll need a tow bar like the non-binding Blue Ox Ascent, part # BX4370. A non binding tow bar allows you to attach and unhook your vehicle easily even when on uneven terrain and when the vehicle isn't perfectly aligned behind the motorhome. Safety cables are included. You'll also need a wiring solution like the Roadmaster Diode System, part # RM-15267 and a supplemental...
