Features to know about

Built for Reliable Flat Towing: Fixed-Arm Base Plate That Bolts to the Chassis

This Blue Ox base plate kit gives you solid, secure connection points for your tow bar when flat towing. It bolts directly to the chassis with the included hardware, so there’s no welding needed. The sturdy design spreads towing force evenly to help protect your suspension from strain on long hauls. With its durable steel build and rust-resistant powder coat, it’s made to hold up through years of road use.

Keeps a Clean Front End: Low-Profile Reinforcements for a Streamlined Look

When you’re not towing, the low-profile reinforcements keep the front of your vehicle looking clean and factory-finished. The crossbar support beam blends in well with the bumper, and the fixed draw bars stay visible but unobtrusive. It’s a practical setup that doesn’t leave bulky parts sticking out or take away from your vehicle’s appearance at camp or in your driveway.

Simple Weekend Install: Straightforward Bolt-On Setup

Everything about this kit is designed for easy installation without special tools or welding. It mounts securely using existing chassis points and comes with all necessary mounting hardware. The straightforward layout makes it a solid DIY project for anyone who prefers doing their own work before hitting the road.

Keep Your Tow System Working Together: Compatible with Popular Tow Bars

The base plate pairs directly with Blue Ox tow bars like the Acclaim #BX4330 for a smooth connection every time. It’s also adaptable for use with Roadmaster tow bars when combined with adapter RM-031 or RM-031-5, and with Demco tow bars using adapter DM9523041 (each sold separately). This flexibility means you can keep your existing gear working together without having to replace your whole setup.

Plan Your Setup Confidently: Exact Fitment Measurements

For reference, the distance between brackets is 24" and bracket height is 13-1/2". That lets you plan your tow bar height and any high/low adapter needs before you start towing. Backed by a 3-year warranty, this setup offers solid peace of mind once you’re rolling down the highway.

I had a simple ball hitch setup for my 1999 Jeep Wrangler for towing behind our RV. Our first trip out with it, the bolts that attached the bar connectors to the front of the Jeep came loose. I was fortunate that they didn't come out completely and cause a major accident. I was able to tighten them again, and we had no additional issues on our trip. Of course, this made me extremely nervous with my 'budget' route to tow the Jeep so I began looking for a better, more reliable solution.

Blue Ox was the name that kept coming up so I purchased the BX1120. The build quality is outstanding, it's extremely solid and very durable. Installation time was about an hour and a half once I had the right tools, couldn't find my 1/2 inch socket set! I'm using the Blue Ox Alpha tow bar with this setup.
I will say that having a second set of hands to install is valuable, my son had to come help me get the drivers side bolts in while I held the steering housing in place.

All in all, I'm very pleased with the product. It went in easy and should save my nerves on our next road trip!

After market front bumper (Plenty of clearance with this specific mount)



by:

A well-built, stout and heavy-gauge base plate with beautiful welds. It brings peace of mind for towing my Cherokee Sport cross-country behind my Class C without worry of mechanical failures on the open road. Because so much money and liability rides in tow, Blue Ox is the first choice.



by:

First of all, the staff at etrailer has always been there with answers with anything. Fitment, installation, usage etc. Second. The install was easy with the enclosed instructions. I did it by myself with only getting help to raise and lower the bumper. After several thousand miles of towing, still tight and still looks great



by:

1 year later, it’s been used for over 1500 miles and held up great. I did the install and had a weld shop tax the bolts do they wouldn’t back out.



by:

I'm not giving the products the stars as much as the woman who helped me select them and turned me onto the "road-master" product line. Road-master had a "towed-car" hitch for my 2002 Mazda Protege. It was a blessing to have met her acquaintance.



by:

Very simple to install, just need to drill a few holes in the frame. Comes with everything you need except a couple basic washers (mine came with 3 lock washers and 2 standard flats for 4 bolts)…

Would be nice to have the torque specs also in the instructions but the busted bolt is on me!



by:

Perfect fit, well built of high quality materials. In my mind you just can't get much better than Blue Ox. The only issue is that the BX1120 doesn't have removable twist lock tabs. The fixed draw bar mounting tabs are at just the right height and position to play havoc with your shins when the draw bar is not installed. I solved that problem with a shin guard I made of 2 inch schedule 40 PVC. (see photo) Fits perfectly, guards the breakaway switch and lighting connector when not in use, and solves the shin interference problem.



by:

Base plate is well built and fit well. As I would expect from Blue Ox products. My only complaint and the reason for 4 stars would be the horrible instruction. Pictures are absolutely horrible. Not a big deal for the mechanically inclined, but not everyone fits that category.



by:

Outstanding communication. Outstanding customer service. Outstanding towbars and baseplates. Will be back.



by:

Once again just great service from etra iler



by:

Easily installed but proper alignment needs to be maintained before drilling the additional hole required for through bolts.



by:

Not a bad install the nuts on the end of the wires was a little strange and odd to use and bend….. worked out great haven’t towed it yet ….bolted in and ready. There’s not really any place on thes 06 Wrangler to put those safety cables to the frame. Alex T in sales was great.



by:

The kit is well built and comes with all the necessary hardware to install. Installation was a breeze and asthetically blends in well with the front of the truck. Great job on the design and the production!



by:

We really like our blue ox towbar mounts from etrailer. We're excited to be able to flat tow our 2001 F-250 with our ATV in the bed. Real game changer,, Thank You etrailer
A few pictures of how I attach it



by:

4 it's in solid, but the [finish] that was used killed it from being a five.

The installation took about four hours. I had a tight interference fit between the frame rails. I wish I had an 18-24" linear ram, but I didn't. So two hydraulic floor jacks, with 4 - 24" welding clamps, and two 12" C-clamps, a short 2# sledge did the trick. Nothing a little spray paint can't fix. Four bolt holes lined up nicely. Two 1/2" drilled holes from the bottom were easy leverage to set up. Two 1/2" drilled holes inside to outside, were quite the challenge to get behind the drill. All fasteners now torqued to specification with red locktite. Added the 1/2" safety cables, made an adjustment in the lower airdam. And presto, here you have it. Now time to set up diode kit, and brake away switch installation.

After a year and many miles later, the Base Plate still works great. It made towing so much easier compared to towing with a dolly. Money well spent!



by:

This was a perfect fit and straight-forward self-install project.



by:

Easy to install. Fit great and works like a charm. Towed the vehicle over 4,000 miles withour any issues whatsoever.



by:

fast service and looks to be of good quality I have not installed yet would order from e-trailer again.



by:

it still looks nice and working as it should. i made it also double as a base to bolt up my winch. the bonus thing is when i need to tow it i can undo 4 bolts and take my winch off. i think you guys at e-trailer should consider making something like this as a option. i have pictures of it installed but how do i send them to you?
