On most automobiles, the brackets are mounted within the grille, where they remain not only unseen, but protected from scrapes and scuffs, as well.

  • 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...

  • 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.

  • 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...

  • 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.

  • 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...

  • Parts Needed to Flat Tow 2013 Jeep Wrangler Sport Stock
    Hey Richard, to flat tow your 2013 Jeep Wrangler you will need a base plate kit to start. You can go with the Blue Ox part # BX1126 or the Roadmaster part # RM-521448-4. Personally I like the Blue Ox base plates as they are the easiest to use but Roadmaster is a solid option. For a Blue Ox tow bar you'd want the part # BX7420 or for Roadmaster part # RM-520. For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice...

  • 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...

  • Are Removable Arms for Roadmaster Base Plate Kits Available
    Hey Ed, yes we do have replacement arms for Roadmaster base plate kits with the part # RM-ARMS. These arms are not interchangeable with other manufacturers. They actually aren't even interchangeable with the same manufacturer (if it's Roadmaster) as the arms themselves are all slightly different for each base plate kit fit. Sounds like you have a Roadmaster base plate kit on your vehicle that is missing the arms is that correct? If so, you'd need the # RM-ARMS.

You didn't mention which version/style your Wrangler is, so I have all the options that will fit a crossbar style tow bar (which all the Stowmaster tow bars are): Standard factory bumper with no winches or guards (does not fit Winter, Hard Rock, or 75th Anniversary models): Roadmaster Crossbar-Style Base Plate Kit - Removable Arms # RM-521448-4 Winter...

  • Adapter for Demco Commander II Tow Bar to Roadmaster Base Plate Kit on a 2017 Wrangler Rubicon
    Hey Earl! The Demco Commander II Non-Binding Tow Bar # DM9511012 can definitely be used with a Roadmaster base plate kit! You'll need the Adapter # DM9523001 for the Crossbar-Bar Style # RM-521448-4, or the Adapter # DM9523032 for the Direct-Connect # RM42FR. If you have the standard factory bumper, you can also use the Demco Base Plate Kit # DM9519292 so you don't have to get an adapter. Do you already have the base plate kit?

  • Is Roadmaster Direct-Connect Base Plate Kit Compatible With Roadmaster Stowmaster
    Hi Dale; the Roadmaster Direct-Connect Base Plate Kit # RM-521448-5 only works with motor-home-mounted tow bars so it is not compatible with the StowMaster. If you want to use the StowMaster you need to swap out your base plate kit and use the # RM-521448-4. The other option is to sell the StowMaster and get a new tow bar like the # RM-520

  • Availability Of Base Plate For A 2015 Volvo S60
    Hello Patrick. We do not offer a base plate for the 2015 Volvo S60. According to Volvo, flat towing of any model whether manual or automatic is not recommended. The only approved way to tow is with either a tow dolly, or with a car trailer with all 4 wheels off the ground. Since flat towing is not recommended, base plate manufacturers are not going to make a base plate for this car. You may be able to tow it using a tow dolly like the Demco Kay Kaddy X # DM9713093, but you will want to...

  • 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.

  • What Aftermarket Jeep JK Bumpers Are Compatible with Roadmaster Base Plate Kits
    When the Roadmaster # RM-521448-4 base plates are designed, they're designed to work with the standard factory bumper only. Due to the myriad of aftermarket bumpers available for the Jeep Wrangler JK platform, it'd be near impossible for Roadaster to test fit with all of them. The only aftermarket bumper Roadmaster mentions that's compatible with their base plates is the Warn Elite 101420 which is compatible with the # RM42FR direct connect base plate or the # RM92FR crossbar-style base...

  • 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 Braking System for Flat Towing 2015 Jeep Wrangler
    A Tow Bar and Braking System like the Ready Brute Elite combines a tow bar with a built-in supplemental braking system. The Ready Brute Elite braking system activates the brakes on your towed vehicle when your RV stops or slows. Basically the braking force of your RV works in combination with the forward surge of your towed vehicle to make it slow down and stop - like a surge brake trailer coupler. Instead I would recommend a proportional braking system like the Roadmaster tow bar braking...

  • Fitting the Roadmaster Tow Bar Adapter # RM-032 to Roadmaster Base Plate Kit 1432-1
    I believe the problem that you are seeing is that you do not have the arms for your Roadmaster base plate kit. You can order new arms by going using part # RM-ARMS and filling out the replacement arms form. Once you have the replacement arms you will then have a fully functioning base plate kit like part # RM-521448-4 which replaced the kit 1432-1 that you mentioned. This will then allow you to use the Roadmaster Tow Bar Adapter # RM-032 with your Blue Ox Aventa II tow bar.
