Features to know about

Clean Front Look When You’re Not Towing: Hidden Bracket Design with Removable Arms

When you unhook from your RV, this setup leaves your front end clean and uncluttered. The crossbar-style hidden brackets mount to the frame, and the square drawbars remove easily using two hitch pins. Once the arms are off, the remaining brackets sit tucked behind the grille and are nearly invisible. It keeps everything protected from scrapes while keeping the front of your vehicle looking stock.

Strong and Steady for the Long Haul: All-Steel, Computer-Cut Construction

This base plate kit uses computer-cut, all-steel construction for maximum strength under load. The design spreads towing forces through the frame so everything stays stable mile after mile. A black powder coat finish resists corrosion and holds up against road debris, so the hardware keeps its integrity through cross-country trips and changing weather.

Simple DIY Install: Custom Fit with No Welding Required

If you like turning wrenches on the weekend, this setup is designed with you in mind. The kit bolts directly to factory points for a precision fit—no welding needed. Clear instructions and included mounting hardware make it straightforward to line everything up and bolt it down securely. It’s a clean install that stays tight and solid once in place.

Ready for Your Tow Setup: Works with Roadmaster Tow Bars Using Quick-Disconnect Crossbar

Already have a Roadmaster tow bar? This base plate kit is built to work with it when paired with the Quick-Disconnect Crossbar Assembly (910021-00, sold separately). That setup lets you connect or disconnect fast without crawling under the vehicle. Once hooked up, hitch pins lock everything in tight so you can roll out confidently every time you tow.

The Jeep project went very well everything fit great and worked well. I really love Roadmaster products and quality and your company is the best place to purchase them. I sold the Jeep and replaced it with a new 2019 Chevy Equinox 2.0 L AWD and just purchased and installed the following items from you and installed them, RM-156-25 & RM-156-75 Battery Charge Line Kit, RM-146-7 Flex Coil Kit, RM-523193-4 EZ4 Plate Kit, RM-88333 Custom Seat Adapter, RM-751489 Stop Light Switch Kit and a RM-98160 Second Vehicle Brake Kit w/brakeaway. All these parts were in stock and arrived quickly and normal with you people, I really enjoy the o-line vidios as I do all my own installs. Thank you so much for your great service.
I will attach pictures of my install, you will see how I was able to fab a bracket and attach it to the existing mount on the base plate to mount the brakeaway switch and the air connection for the brake system.
I also fabricated a tail light bar as I didn't want to use mag-lights or splice into the factory lights and bulbs installed into the lights would not work as the factory brake lights will come on when the brake system is applyed and the turn siginals would not be visable.
Thanks for all you do, I would and do recommend you people to everyone who needs your products. Rob

The installation took me about 7 hours, the facia removal was tedious , between the installation videos and instructions, I performed the task. This bar has one con, the pull rings on the removal bars are flimsy , my first pull stretched one out. I’m sure trailer has a fix for this under warranty, I hope.



by:

Etrailer was very easy to do business with and made it simple to ship my order directly to the RV shop that was going to install it. This was my first order from them, but I will definitely consider future purchases from them if I'm in need of something for my RV.



by:

The representative (Sarah) was very helpful and knowledgeable, the prices are very reasonable and all my items arrived on time. When I called with a question, she was very polite, friendly and genuinely sounded like she enjoyed her job. When I discovered one of the items I ordered wasn’t needed, getting help to return was hassle free. I would recommend etrailer to anyone that needs anything RV or trailer related. I will definitely do business with them again. I am impressed.



by:

We towed our 2004 Subaru Impreza WRX STI 3000 miles last year, this is an ideal setup, discreet when not in use, solid, and easy to get on/off. Very please with the support I received from Roadmaster as one of the bolt was missing, was sent super quickly.



by:

Not an easy install on a Trax but it is very well made and gives a clean look. I did customize by cutting down the 6 pin bracket supports to get it flush with front of the car.



by:

Install pretty easy. You will have to change directions of one bolt due to obstruction ( frame). Cannot torque a few of the bolts. These are the ones with wire attached.
Rock guard needed addition trimming from factory instructions.



by:

Awesome delivery speed, and a well made base plate for my 2007 Element. Installation was a breeze (thanks to my son’s heated shop) and I had to do no cutting to make this fit. I had a Stowmaster tow bar that came with my RV and etrailer was able to steer me to the correct missing parts to make this a really affordable installation. Now to get out of this snow!



by:

Purchased for a 1997 Subaru Impreza. Delivery was amazingly fast! I didn't have it installed until a few months later, as my travel plans had stalled. It didn't quite bolt right on, but was close, and a friend had to modify it some to make it work. I still hear a grating noise when I turn too sharp on one side, but otherwise it's fine.
The front connection plates didn't line up with the holes, so had to have those modified, as well, in order to line up and attach to the tow bar. Once the new holes were drilled, I was able to hook up and go.
It's relatively easy to connect after finding a way to do it alone.
I've towed from CO to TX and all over TX with it with no problems.



by:

After ordering the wrong crossbar, etrailer sent the correct one for our Mini Cooper quickly. However I did have to modify most of the holes as the cross bar didn’t quite fit (but close). I had to drill the three main bolt holes to 11/16 so that the bar would go over the Mini’s 3 main bumper bolts on both sides. The two lower bolt holes (each side), needed to be drilled out 3 sizes larger to accommodate the 4 bolts that come with the kit. I had to drill out the Minis lower holes to better align with the crossbars lower holes. I would also like to note it being a pain in the knuckles to reach one of the three (each side) bolts to put the stock nuts on the bolt and then try and get them tight. (The main bolt pattern for the upper bumper is diamond shape, one up tow bolts lower. (The lower “inside” bolt on each side is the one that is hard to get to and tighten.) Sorry I didn’t get picks, I was in a rush to get the car back together. There’s an angle piece on the cross bar that blocks the hard to reach bolt, it would be helpful if that could be made more accessible to reach.



by:

Fit and finish is great, the illustration for what you trim on the bumper isn't great but otherwise pretty easy install (I ended up measuring between the mounts on the draw bar and just trimmed accordingly)



by:

I’ve been purchasing products from ETrailer since 2005 and all the products I’ve purchased have been a great value. The products mentioned above installed perfectly and with the direct assistance from ETrailer everything fit as suggested. I will always interact with ETrailer as needs present themselves.



by:

Overall the installation was great, however the process of drilling 3 - 1/2" holes in that little bumper that has a Rockwell Hardness of about 60, seems to be a bit over the top.The instructions are spot on, delivery was great, the quality of product was accurate. I am a happy boy!



by:

Replaced same part that was damaged in a crash. I had used my original one for close to ten years without issue. Fast shipping from etrailer.



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 brackets are very well made and once installed, are perfect. The reason a four star rating is because the drilled holes in the bracket did not align properly on the driver's side. I had to get a sturdy metal bit and redrill the hole. Once I did that, the installation was complete. FYI, I bought the tow bar with this product and it is perfect.

Good quality, fast shipping, and fit aftermarket bumper

    The Roadmaster Sterling tow bar # RM-576 is compatible with all Roadmaster base plates including XL base plates # 1183-1 for the 2007 Toyota FJ Cruiser. The XL base plates will use the quick disconnects that came with the tow bar. It sounds like your Jeep has the EZ5 base plates but that type of set up is not available for the FJ Cruiser. The tow bar already has safety cables and a 7- to 6-Way so what I recommend for wiring on the FJ is # TR118821. You would have to cut off the 4-Way that...

  • Will Roadmaster Base Plate Kit Fit 2010 Toyota FJ Cruiser With ARB Bumper
    Hi Bonnie, all of the base plates for your 2010 FJ Cruiser are designed to fit vehicles with the factory bumper. You might be able to get the # 1183-1 to fit since it sits so low, but we have no way of confirming this. I recommend looking through the instructions linked further down on this page and comparing it to the bumper. Bumper modification may be required to make room for the arms and brackets.

I would contact the manufacturer and see if the bumper can be used for flat towing. If so I recommend going with Item # RM-520 and Item # RM-035-1 if the shackle mounts are 1" thick and Item # RM-035 if the shackle mounts are 3/4" thick.
