Features to know about

Made for a Clean Front End: Hidden Base Plate with Removable Arms

This setup keeps your vehicle looking stock when you’re not towing. The main body stays concealed, so there’s no bulky metal showing out front. Once the removable arms are out, the clean, OE-style look is back. It’s a simple way to keep things tidy without sacrificing strength or function.

Connect and Go: Twist-Lock Tabs for Easy Hookup

Hooking up is quick thanks to the twist-lock attachment system. The tabs rotate into place and secure firmly, keeping setup smooth whether you’re at home or at the campsite. No extra adapters or tools to fumble with—just twist, lock, and you’re ready to roll.

Built Strong for the Long Haul: Welded Steel Construction

The base plate is constructed of welded steel and bolts securely to the chassis—no welding required. It’s physically tested to the vehicle’s gross vehicle weight rating (GVWR) and spreads towing forces evenly to reduce strain on suspension parts. A high-gloss black powder coat, co-cured in a rust-resistant Bonderite coating, protects it from corrosion so it can handle cross-country miles without worry.

Keep the Tow Bar You Already Own: Compatible with Curt and Blue Ox

If you already have a tow bar setup you like, this kit fits right in. It’s directly compatible with both Curt and Blue Ox tow bars, so there’s no need for adapters or extra pieces. That means less guesswork and a faster route from driveway to highway.

DIY-Ready and Straightforward: Bolt-On Install with Included Hardware

This kit includes everything needed for a clean bolt-on installation—no welding required. The process is straightforward with basic tools, making it manageable for most DIY setups. Once installed, the connection points line up just right with a distance between brackets of 30.5" and bracket height between 13.5"–17". It’s built for precision fit and long-term dependability right out of the box.

The package was delivered to my home with no damage. The baseplate with its parts along with the rest of my order was all packed neatly with extra cardboard and paper packaging material around everything so nothing would get damaged in transit.
The installation instructions were clear. The parts fit perfectly. I’ve purchased parts from etrailer before and never had any problems. Also, the few times I’ve had questions I’ve always been able to talk to someone who is knowledgeable and very helpful.

Base Plates mounted on my 2022 Ford Bronco is holding up 100. Great quality finish that has not rusted. I have seen base plates from other companies being installed on Broncos and they are making major modifications. Not my Curt Custom Base Plates. An easy DYI with no major modifications. We have towed our Bronco 13,000 miles behind our Class A and its a flawless tow. These base plates were also priced much better then other brands. Thank you Etrailer!

Jaime was very helpful in getting the right baseplate for my Jeep Cherokee and in retuning the wrong item which I ordered myself.
The baseplate installed easily and will be used for the first time next week. Also, the curt base plate did not require any trimming whatsoever of the plastics on the front of the car.
Thanks Jaime

This is not the first time I have purchased from ETrailer, but by far the best experience yet. I was treading in uncharted waters and decided to call, i happened to get Paula S. And she was able to educate me on the subject at hand. She also made sure I was ordering all the right parts for the task at hand. I received the two boxes of parts and assembled everything on the vehicle and noticed i was missing something so I called back and talked to Ashley. She assured me that Paula did order the missing part and that it would be here the next day. (Delayed due to holiday) You can sure tell both ladies love their jobs and liked taking care of us customers. I will always try to deal with them when I need something towing related.

Hey Richard! Paula an Ashley are always on the ball so I'm glad that they got to help you out. I see you pretty much got a full flat tow set up, have you started making any plans yet of where to venture off to yet?

Great Base plate kit! Very easy to follow instructions even with my aftermarket bumper with winch. It fit perfect. The only issue I have is where the safety cables attach to the base plate….the cable connectors are too big to fit through the holes because the Jeep’s frame blocks part of the hole. See photo with red circle. I will have to get a smaller connector.

Etrailer is with out a doubt the best supplier in the market today. they are on time every time and there support is excellent.

Fit like it was made for it. :) Only issue was the fishing wires for the bolts in the frame. They would not fit through the holes in the locking plates so I couldn't use them. I used a magnet stick instead and it worked well. I did not put on the safety cables around the frame. I figure since this thing bolts to the steering box, if it comes off so does the steering box and then I have much bigger issues that these cables are not going to help.

Everything fit like it was supposed to. Not to difficult to install. A couple hours at most. Seems to be a quality product. Thanks

Nothing an extra set of hands can't do! I am glad you were able to get it installed. Where are you headed first with your new setup?

Wasn't to hard to install with a helper to get bumper off my truck. Had bumper pulled and installed baseplates in about hour and a half.

After one year this tow bar is working flawlessly to date.

by:
Easy to install with typical tools found in about anyone's garage. Took maybe an hour or so to do. We have pulled our Ranger about 2000 miles behind our RV without any issue.
by:
This base plate kit worked very well with the Blue Ox Acclaim non-binding tow bar - coupler for 2" ball (code BX4330). We towed a 4 door Rubicon over 2000 miles and the setup worked great. The bar is very easy to couple and uncouple. The removable arms work exactly as advertised. I did have to cut two small slots in my custom bumper to install the base plate, but the slots are not in strength critical areas. The installation instruction are clear and good.
