Toyota 4Runner

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.


Gwen was extremely helpful and pleasant and I am sure I'll be back next time I need something for the RV.


These were a great fit and worked perfe ct.


Very helpful in helping my select the correct parts I needed. Every thing arrived as expected and fit perfectly.


Good fit. Easy install. Works.



2017 Toyota 4Runner

thank you for the fast delivery




etrailer service is and has always been stellar. My order was correct and was delivered very quickly. The only reason I made this a four instead of a five was that the rear bolt position of both base plate brackets where welded on crooked. Each small plate was at a different angle from each other. In my opinion whoever welded them wasn’t paying attention to quality control. Because I was on a time crunch for my departure on a trip and could not wait for replacements (and I needed the vehicle for local driving) I made the brackets work. Other than that the installation went smoothly and I was able to test tow my 2004 CRV a couple of times without incident.


Very impressed that they're the exact fabbed fit, and easy to install! These tow base plates are super sturdy!


Item arrived earlier than predicted after viewing a very complete tracking system. The information was very clear and precise. Good job! I am 75 years of age and installed the baseplate myself. Only a couple of minor issues. One pin would not insert. Welding blob in the way. Filed it smooth and problem solved. The video was excellent but was a bit different in that it showed a different method o rear bolt installation, however the instructions on paper showed the correct way. Reinstalling the front clip had presented some difficulty. I suggest really watching the inner fender position relative to the front clip before removal. All said all went well. The finished look is great, (see pictures). Great product!


Base plate 1910 install on 1999 Landrover disco 2

the base plate arrived fast (as does everything I have ordered from etrailer). It was a bit bent on arrival but Becky sorted me out and offered to replace it but it was easy to bend back (with a 3lb hammer).

The included instructions were great for removing the bumper but nor much else. Possibly because my Landy is a 1999 disco 2 and the pictures were of a 2002.

I have included some pictures of stuff I wish I had known. Firstly I had to loose the recovery loop on the driver side as the base plate would not fit over it. The chassis frame has steel tubes inside the bolt holes so the amount of drilling is minimal (I ordered a drill bit that they suggested but in all honesty could have opened up the holes with a file easily).

You need to oval out the aluminum crush cans before you replce them or the new bolts will not go through. The center mount bolt just needs the plastic mount for the center screw on the scoop cut out and there is a bog square hole on the top of the member (thats why you need to big square piece of steel on the top of the center bolt)

Mine was obscured by the torsion bar so I ended up dropping it to drill out the hole and get the bolt in straight.

It was easy to bolt up to the frame once everything was prepped and do yourself a favour and buy loctite red for the bolts - you don't want to be going in there again.

The bumper template was a good start but I had to reshape mine a lot particularly as the hole on the baseplate ended up halfway through the bumper and I had to do a lot of enlargement at the bottom to attach the safety wires.

The photos should make more sense of some of my description


The baseplate and crossbar arrived one day earlier than expected. Directions were included which made the installation pretty easy.
I am happy with etrailers products and will buy from them again.


Everything looks good for us, but we have one more part that we are waiting on before we can install on the truck plus it's raining out here in Washington State. when it's time to put it all together we will take a picture and send it.


My husband and I were able to install the Roadmaster base plates on our 92 Jeep Cherokee in just a couple of hours. It went on pretty much the same as the demonstration video on the etrailer web site. The minor differences were addressed in the printed instructions that were included in our package. We haven't put it to the test yet as we still need to tackle wiring for the Roadmaster Even brake system that we purchased second hand. We will be towing our Jeep with our 93 Safari Trek. Customer service provided by Marty was excellent. I will provide pictures at a later date.


This base plate was installed on a 2008 Kia Spectra. The bracket is strong and not really hard to work with HOWEVER,,,,,,,,,, I am used to the BlueOx base plate which is much easier to "hook up". Unfortunately, BlueOx did not make a base plate to fit my vehicle. That is not a big problem as I'm usually not in any hurry and it only takes maybe 5 minutes longer to "hook up".

The biggest problem with the RoadMaster base plate is that due to the way it is bolted to the frame, it only allows for a 6-inch ground clearance on the front of the vehicle. I have to be very careful with any "dips" in the road, especially on cross streets. Six inches may not sound like much but since the tires are several feet behind the base plate, it reduces that ground clearance greatly. It also will not clear the concrete "stop blocks" in front of many parking spaces.

If you are not very careful and keep this in mind, you may likely bend the frame of your car when you come to one of these sudden impacts. I haven't bent anything yet but it has certainly been shocking when it hits. Most of the time, the impact will cause the base plate to scrape and lift the car to the height to clear the obstacle.

I've attached a picture with a ruler in the view.


Good information and prompt shipping.
plate is solid and install and use instructions are excellent.
Be warned that product install is drill two holes and install 3 bolts, BUT the entire front panel has to be removed and replaced. Not difficult, but time-consuming.
Seat bracket is solid and install and use instructions are excellent.
Brakemaster kit is good quality, but instructions are not as good as most Roadmaster products. Instructions for air line install are especially weak.


The hardest part of the installation is getting the grill off and back on. Of the six preexisting holes all but one lined up the sixth hole was off about a half inch but the car had hit a deer a few years ago.

This was a very simple install. This is my 4th baseplate I have bought and 2 pintle tow bars. Always excellent craftsmanship


What a job to install this thing! Does not line up with any of the existing holes. It is close, but still a real bear to get into place. Instructions do not have any photos. The instructions also list bolts that are not in the kit. I strike that up to a misprint, but still very confusing. It requires a drill bit, that I could not find any any hardware store or auto store. 17/32 drill bit? Maybe include that with the parts? Definitely helps to have another hand and a lot of patience. No videos online about this install and what to do about all the gaps where it does not properly line up at the right angle for towing.


Installed on a 2010 Ford Ranger Sport 2wd
towed over 10000 and not one issue. I did the install without one issue, picture perfect, I did use a online video to get a general idea of install otherwise I primarily used manufacturer's. . Be sure to use the recommended/ required locktite product.


Dealing with eTrailer to purchase and install my own base plate made me feel like I had a team of experts at my disposal. The installation is not easy and not for everyone, but with the help of chat sessions and videos, I believe that most people with some good working knowledge of tools can get it done.


Fast shipping and installation went smoothly with the provided instructions. The only complaint was the shipping box was in very bad shape - I think due to the weight of the base plate. A sturdier shipping box should be used.

  • 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.

  • 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.

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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.

  • 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...
