    • Arms click to lock in place in brackets
    • Built-in pull rings let you unlock arms so you can twist and remove them
  • Computer-cut, all-steel construction provides exceptional strength
  • Black powder coat finish is durable and corrosion resistant
  • Simple installation - no welding required
    • Custom base plates ensure a perfect fit for your vehicle

The drawbars, or front arms, on the crossbar-style series base plate kit are supremely easy to mount and remove. Just insert them into the brackets and twist to lock them in place. To remove, simply twist the arms back and pull them out. Once the drawbars have been removed, the remaining brackets are virtually invisible. On most automobiles, the brackets are mounted within the grille, where they remain not only unseen, but protected from scrapes and scuffs, as well.

  • Adapter to Use Blue Ox Tow Bar With Roadmaster EZ Crossbar-Style Base Plate Kit
    The base plates you have are the Roadmaster Crossbar-Style Base Plate Kit # RM-521448-4, which are the EZ4 model of base plates, so the correct adapter to use a Blue Ox tow bar is the Roadmaster Tow Bar Adapter # RM-032. This will work with Blue Ox Aventa, Aventa II, Aventa LX, Alpha, Ambassador, Kar Bar, Aladdin, Alexxa, and Acclaim tow bars, as well as all Blue Ox A-Frame tow bars with 1 or 3 pronged attachment. I've added links to video reviews for you to check out as well.

  • Recommended Flat Towing System for 2016 Wrangler JK 2 Door
    I'm happy to help get you everything you need for your 2016 Jeep Wrangler JK to flat tow it. You have done your homework so my recommendations will be in line. I recommend the Roadmaster Crossbar-Style Base Plate Kit - Removable Arms # RM-521448-4 you suggested which will utilize the crossbar of the Roadmaster Sterling All Terrain Tow Bar # RM-576. This is a great combination with the tow bar also having the wiring cord and the safety cables integrated. Then you will use the Hopkins...

  • Will a Roadmaster StowMaster Tow Bar Work With a Demco Base Plate on a 2012 Jeep Wrangler?
    The Demco Base Plate # DM9519292 that was installed on your 2012 Jeep Wrangler is going to require a Demco compatible Tow Bar # DM9511012. It is not compatible with your StowMaster Tow Bar # RM-501 as you have to have a Crossbar Style Base Plate # RM-521448-4 for the tow bar to attach.

  • Base Plate Kit Recommendation for 2014 Jeep Wrangler 4 dr. Unlimited
    If you have a base plate kit set up on your 2008 Jeep Wrangler you most likely have a flat towing setup already and just need a new base plate kit for the 2014 Wrangler Unlimited. For that you would need the part # RM-521448-4 which is a confirmed fit.

  • Parts Needed to Flat Tow 2013 Jeep Wrangler Unlimited with Aftermarket Bumper that Has D-rings
    Flat towing a vehicle such as a Jeep Wrangler behind a Class C motorhome such as the Dynamax Force 37BH HD will require a few items including the tow bar and braking system. The Blue Ox Patriot braking system # BLU37TR that you referenced is a very good selection. I linked overview articles on flat towing that cover each of the items needed. These are a good starting point. But first I suggest you check with the bumper maker to confirm it is rated for towing. Not all aftermarket bumpers...

  • Parts Needed to Flat Tow a 2013 Jeep Wrangler Sport or a 2016 Jeep Wrangler Unlimited
    To flat tow your 2013 Jeep Wrangler Sport behind your RV you will need a Base Plate Kit, Tow Bar, Safety Cables, Vehicle Tow Bar Wiring, a Supplemental Braking System, and possibly a High-Low Adapter. There are a couple of great brands that we carry for all of this equipment and a lot of it depends on what kind of setup you want when it comes to the brand. The 2 dominating brands for the Base Plate and Tow Bar are Blue Ox and Roadmaster. Although they are very similar in quality I prefer...

  • Parts Needed to Flat Tow a 2017 Jeep Wrangler Unlimited Winter Edition
    The base plate kit we carry to fit your 2017 Jeep Wrangler Winter Edition is Blue Ox # BX1133. It's the only kit we offer that fits the Winter Edition. In addition to the base plate kit you'll also need a tow bar, wiring, a supplemental braking system, and likely a high-low adapter. To pair with the Blue Ox base plate kit I recommend the Avail # BX7420 for a tow bar. It has a higher weight capacity than most at 10,000 pounds. Also, the safety cables are included. To power the Jeep's...

  • 2017 Jeep Wrangler Unlimited Base Plate Recommendation for Falcon 2 Tow Bar
    You'll need a new base plate kit for your 2017 Jeep Wrangler Unlimited Sahara as the older style on your 2006 Wrangler isn't compatible with your newer vehicle. There are 2 style choices we have for your 2017 model that will also work with your Roadmaster Falcon 2 Tow Bar # RM-520: - Direct-Connect # RM-521448-5 - Crossbar-Style # RM-521448-4 I prefer the Direct-Connect style because it's less weight you have to deal with and the connection is a little easier to make.

    You can utilize the crossbar mounting system on your Roadmaster StowMaster Tow Bar # RM-501 as long as you use a Roadmaster Crossbar Style base plate on your 2013 Jeep Wrangler. We have a couple of different options depending on the sub-model of your Jeep: Standard Factory Bumper - # RM-521448-4 (won't fit 10th Anniversary Rubicon or Moab Edition) 10th Anniversary Addition - # 1444-1 (won't fit with American Expedition bumper) Warn Elite Bumper 101420 - # RM92FR Warn Elite or Moab Edition...

  • Which Base Plates For Towing Will Fit A 2010 Jeep Wrangler Unlimited
    Both the Roadmaster EZ4 Base Plate Kit # RM-521448-4 and the Roadmaster EZ5 Base Plate Kit # RM-521448-5 will fit your 2010 Jeep Wrangler Unlimited if it does not have an aftermarket bumper, winch, or guards. I recommend the Roadmaster EZ4 Base Plate Kit # RM-521448-4. The Roadmaster EZ series base plates are our most popular base plates. They will fit all the Roadmaster tow bars and they have the hidden bracket design. The EZ5 series base plates will not work with tow bars that require...

  • Can Front Receiver be Installed on 2015 Jeep Wrangler Unlimited w/Base Plates Already Installed
    The base plates and front mount hitches (which you would use to mount a winch) install at the same places on the frame of the 2015 Jeep Wrangler Unlimited so you cannot have both at the same time. I recommend putting a winch at the back of the Jeep. For a 2 inch trailer hitch you can use the Bulldog Winch receiver mount # BDW20155 . Then you can attach a Superwinch electric winch. I have linked the Superwinch models for you.

  • Can Blue Ox Rangefinder II Tow Bar Be Used to Flat Tow a 2016 Jeep Wrangler
    Your Rangefinder II Tow Bar BX4322 has a unique attachment system and the only adapter kit we have to match it are the Roadmaster Base Plates Adapters # RM-037. The adapters aren't compatible with the etrailer Invisible Base Plate Kit # e98949 you're looking at, but they are compatible with the Roadmaster Crossbar-Style Base Plate Kit # RM-521448-4. So in order to continue using your older tow bar you'll need the Adapters # RM-037 and Roadmaster Base Plates # RM-521448-4.

  • Recommended Supplemental Brake System For Flat Towing 2016 Jeep Wrangler Sahara 2 Door
    To flat tow your 2016 Jeep Wrangler, I recommend going with the Brake Buddy Classic 3 Portable Supplemental Braking System # HM39494. This supplemental braking system is very easy to setup and use, and is also one of the more affordable braking system options available. I have attached an installation video on an earlier model Jeep Wrangler to help you with the install process. In order to safely tow your vehicle, you also need a diode taillight kit, safety cables, base plate kit, tow...

  • 2013 Jeep Wrangler Base Plate Kit Fitment with Roadmaster Stowmaster Tow Bar
    Thanks for the photo! It looks like your 2013 Jeep Wrangler has a standard bumper from the factory so you'll need the Roadmaster Crossbar-Style Base Plate Kit # RM-521448-4 to fit with your Roadmaster StowMaster Tow Bar # RM-501. I've attached an installation video of this base plate kit on a 2013 Wrangler for you to check out as well!

  • Base Plate Kit Recommendation for 2017 Jeep Wrangler Unlimited with Roadmaster Tow Bar
    As long as the bumper on your 2017 Jeep Wrangler Unlimited is the standard factory bumper the Roadmaster Kit part # RM-521448-4 that you referenced would be the correct kit. All of the pictures I found for the Freedom Wranglers had the standard bumper. This will work well with your Roadmaster Eagle 5000 tow bar. I attached an install video for this for you to check out as well.

This combination will work well with the Roadmaster Nighthawk All Terrain Tow Bar w/ LED Lights # RM-676. Then you will need a wiring kit for your Jeep. I recommend the portions of the Roadmaster wiring kit # RM-15267 that aren't already integrated into your tow bar. These parts are female spade # RM-300115-00, 3 feet wire loom # 459075-1, 30...
