Features to know about

Made for a Clean Front End: Hidden Brackets with Removable Drawbars

This setup keeps your front end looking clean when you’re not towing. The hidden bracket design leaves only the square drawbars visible—and those arms pull out quickly with two hitch pins. Once removed, the remaining brackets are virtually invisible and stay tucked within the grille, protected from scrapes and dings.

Built to Last: All-Steel Construction with Black Powder Coat Finish

The computer-cut, all-steel construction gives this base plate kit exceptional strength for long-term towing. A durable black powder coat finish protects it from corrosion and road wear, so it stays solid and good-looking even after thousands of miles.

Simple to Mount: Bolt-On Install with Included Hardware

No welding is required here. The kit bolts directly to the frame using the included mounting hardware, making it straightforward for a DIYer with basic tools. Clear instructions make alignment easier and help you get it done right the first time.

Stay Compatible: Works with Roadmaster Tow Bars Using Quick-Disconnect Crossbar

If you already have a Roadmaster tow bar setup, this kit integrates right in. It’s compatible with all Roadmaster tow bars when used with the quick-disconnect crossbar (910021-00, sold separately), so you can keep your existing gear and build out the rest of your flat towing system confidently.

The crossbar-style hidden brackets attach to your vehicle's frame to provide attachment points for your tow bar. The visible portions of the brackets can be removed when you are not towing.

by:

The Base plate kit is well made and came with all the necessary hardware.Installation is relatively straight forward. I did have to enlarge two of the holes that didn't quite line up. But overall I'd recommend it.



by:

Bolted right up. Installation should be done with bumper on, as you can't fit the ends through the louvers without some convincing. Works great so far. Was able to use a Stowmaster 5000 with it.



by:

Installation was a bit trying. Ended up looking very clean and almost invisible.
Using the tow bar worked super easy and our motorhome hardly noticed the Mini Cooper back there.



by:

Came quickly and is very high quality. Great directions/video from road master makes the installation step by step easy to follow.
Skill level is probably at the intermediate level depending on experience.



by:

The #118-3 is a perfect fit on my 1995 Geo Tracker. When you pull off the removable arms you would never know they are there. The Quality is very good easy to put on all you have to do is drill 4 holes the tube on the base plate fits into the tube on the frame of the tracker and with the 2 bolts it is a solid fit. I was worried about the plate nut getting it inside of the frame but it went in easy when you put it over the frame tube and use a thin piece of metal to slide it in place. I’m very happy with it. I probably could of got it on without taking my bumper off but with only 4 bolts holding my bumper on it made it easier

These were a great fit and worked perfe ct.

Helpful chat assist and quick shipping.



by:

All the parts I ordered fit perfectly with no modifications to my 2020 Toyota 4Runner. The info Etrailer has with the part description, Q+A and pictures was very helpful to help me make the best decision on my purchase.



by:

Needed these for my 4Runner. Had to do a bit of grinding on the frame rails to get em to fit. I suspect just different year manufacturing tolerances. All in all, pretty easy to install if you are even semi mechanically inclined. Havent towed it yet but got all the bits and pieces and to fit together just like it should. Easy to remove and good clearance underneath



by:

This base plate kit fit out 2007 4Runner perfectly. Wasn’t difficult to install myself in only a couple hours. Very happy with the product.



by:

very well built. great shipping time. small problem with fitment. nice kit overall.



by:

Installed onto 2017 Toyota 4-runner. Fit perfectly. Was hard getting the one bolt hole drilled through the truck frame, but that is a tool issue, not anything negative about the product. I would recommend this Plate Kit to anyone wanting to flat tow a Gen 5 4-runner.

  • Will the Roadmaster Guardian and Tow Defender Work with the Nighthawk Tow Bar
    I do have an option for you but I spoke with my contact at Roadmaster and they informed me that the Roadmaster Stowaway Storage System part # RM-4000-40 which is used to attach the Roadmaster Guardian Rock Guard part # RM-4000 on the back on an RV will not work with the Roadmaster Tow Defender Protective Screening part # RM-4700. In order to use both the Stowaway and the Guardian on your vehicle with a protective screen you will need to use the Roadmaster Tow Defender Protective Screening...

  • 2016 Toyota 4Runner Cost-Effective Flat Tow Braking Systems and Parts to Tow
    The Blue Ox Patriot # BLU37TR is a popular braking system but there definitely some more cost-effective options that will provide you with the braking you need for your 2016 Toyota 4Runner. If you like the portability of the Patriot 3 then I recommend checking out the Brake Buddy Classic 3 # HM39494. Brake Buddy has been in the flat tow braking business for a long time and this is their base system that basically has the bare minimum when it comes to features but it is reliable and gets...

  • Base Plate & Tow Bar For 2018 Toyota 4Runner
    I checked with our manufacturers and there is one base plate that fits a 2018 Toyota 4Runner, the Roadmaster Crossbar-Style Base Plate Kit # 1185-1. Your 4Runner must have tow hooks, and the base plate won't fit Limited or Nightshade Special Edition models, or models with Kinetic Dynamic Suspension. An accompanying tow bar that will work with these base plates is the etrailer SD Non-Binding Tow Bar for Roadmaster Crossbar-Style Base Plates # e44ZR.

  • Parts Needed to Flat Tow 2016 Toyota 4Runner
    In order to flat tow your 2016 Toyota 4Runner, you will need a base plate kit, tow bar, safety cable set, lighting solution, and a supplemental braking system. A supplemental braking system is indeed required by law in most states and many RV manufacturers will actually only honor your warranty if a braking system is in place when towing. Starting with the base plate kit, the Roadmaster XL Base Plate Kit # 1185-1 that you referenced is a great choice and is confirmed to fit your 4Runner...

  • Recommended Flat-Towing Components For 2011 Toyota 4Runner
    If your 2011 Toyota 4Runner is not the Trail Edition, I recommend the Curt Front Mount Trailer Hitch, part # C31054. This hitch is an easy bolt-on installation and requires no welding. It has a 2 inch receiver opening and would work well for a front mount winch as you described. I have attached a link to an installation video for this hitch on a 4Runner you can check out. If your 4Runner is the Trail Edition then the front mount hitch you will want is part # 31367. Since you said...

  • Parts Needed to Flat Tow a 2014 Toyota 4Runner
    I would be happy to help you get the correct equipment so that you can flat tow your 2014 Toyota 4Runner. Keep in mind that since your manual says not to flat tow your 4Runner with all 4 wheels on the ground that any damage that could potentially be done would not be covered under your warranty even if you have disconnected the rear drive shaft. You almost had everything in your list! To flat tow your 4Runner you will need a Tow Bar, Safety Cables, Base Plate Kit, Wiring, a Supplemental...

  • Flat Towing Setup Recommendation for a 2008 Toyota 4Runner
    For a base plate kit for your 2008 Toyota 4Runner I would recommend the Roadmaster XL base plate kit # 1185-1. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon 2, # RM-520. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground. For lighting you can use the bulb and socket kit, # RM-155, and...

    For a 2007 Toyota 4Runner I have the following recommendations: Baseplate: Blue Ox Base Plate Kit # BX3758. Tow Bar: etrailer SD Non-Binding Tow Bar for Blue Ox Base Plates # e47ZR. This tow bar is going to include the safety cables and comes with an adjustable head to help stay level between the motorhome and 4Runner. Tow Bar Wiring Kit: Tekonsha Tail Light Isolating Diode System with 4-Pole Connector # TR118821. This wire harness will allow you to display your motorhome's traffic...

  • Tow Bar That Works For Roadmaster Base Plate Kit 1185-1
    I do have a solution for you, however, I do not see any way to connect your Roadmaster Crossbar-Style Base Plate Kit # 1185-1 to the Ready Brute Elite tow bar. Your best bet is to go with Roadmaster Falcon All Terrain Tow Bar # RM-522 as this will easily connect to the Roadmaster base plates that you already have for your Lexus. This has a 6,000lb weight capacity and attaches to a 2" receiver. I have attached a demonstration video for this tow bar.

  • Adapter for Blue Ox Aventa II and XL Crossbar-Style Baseplate on 2018 Toyota 4Runner
    Hey Michael! No, the Roadmaster Crossbar-Style Base Plate Adapter for Blue Ox and Demco Tow Bars # RM-033 will not work with your Blue Ox Aventa II tow bar and Roadmaster Crossbar-Style Base Plate Kit # 1185-1, which I can confirm will fit your 2018 Toyota 4Runner. The # RM-033 is a fit for the Aventa II tow bar, but the # 1185-1 is an XL Crossbar-Style baseplate kit, so you would instead need the Roadmaster Base Plate Adapter Bracket for Blue Ox and Demco Tow Bars # RM-032, which has...

  • Compatibility of Roadmaster RM-522 Falcon All Terrain Tow Bar w/ Base Plates on 2006 Lexus GX 470
    According to Roadmaster, their # 1185-1 Base Plate kit is compatible with all Roadmaster Tow Bars, including your # RM-522 Falcon All Terrain model. To complete your flat towing set-up, you'll need safety cables like # RM-643, a wiring kit like # RM-15267, a supplemental braking system like # RM-9400 and possibly a high/low adapter if there's more than a 3 inch height difference between the receiver in the tow vehicle and the base plate on the Lexus. According to my research, that particular...

  • 2006 Lexus GX470 Base Plate Kit for Use with Roadmaster Sterling Tow Bar
    For your 2007 Lexus GX470 we have the Roadmaster base plate kit part # 1185-1 as a confirmed fit that would also work great with your Roadmaster Sterling tow bar # RM-576. 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 you will install on the front...
