Features to know about

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

If you like your setup to look clean when you’re not towing, this design keeps it that way. The main body stays concealed so nothing bulky sticks out from the front end. When the removable arms are off, the base plate blends in for a low-profile, factory look that keeps things neat and out of the way.

Quick Hookups Without Hassle: Twist-Lock Tabs for Easy Connection

The twist-lock attachment makes connecting quick and simple. Each arm slides into place and locks with a twist, so there’s no fumbling with extra pins or misalignment. It’s a straightforward process that makes getting ready to tow or disconnect smooth every time.

Solid and Dependable: Welded Steel Construction That Spreads the Load

This kit bolts securely to the chassis—no welding required—and is built from welded steel for strength and precise fit. The design spreads towing force evenly across the frame to minimize stress on the suspension. It’s physically tested to gross vehicle weight rating (GVWR) standards for dependable performance mile after mile.

Rust Protection That Lasts: Co-Cured Powder Coat and Bonderite Finish

The high-gloss black powder coat isn’t just for looks—it’s co-cured in a rust-resistant liquid Bonderite coating that helps the steel stand up to weather and road grime. This dual-layer finish gives long-term protection against corrosion so your setup keeps performing and looking good.

Keep Your Existing Tow Bar: Direct Blue Ox Compatibility

Already have a Blue Ox tow bar? You can keep it. This base plate connects directly without any adapter needed, making it easy to reuse your current setup. The kit also includes safety cables and installation hardware, so you have what you need for a secure connection right out of the box.

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

Product was fine hardware bag broke open and was loose in box I hope nothing is missing

Great product! I like the quality with which it was built and the 100% fit. The instructions could have been better, but the E-trailer video helped. You do have to have a bit of mechanical aptitude to install this baseplate---not so much the plate but removing the fascia from the vehicle. I have no complains and Jill was extremely helpful when ordering.

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!

Disassembly of the front clip of the Colorado was challenging as far as fit up curt kit worked well. The gal at etrailer was very knowledgeable fast shipping. Finally every time I do business with you I’m never disappointed.

Instructions stink, this installs much lower than the instructions show, several things are far more in the way that the instructions make it seem Also, the installation is into weak sheetmetal, after your torque this to 75 ft lbs, you will see the steel bending and the bolts are no longer flat against the mounts. Vevor level junk for way to much money for what it is.

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

  • Recommended Baseplate For A 2018 Jeep Cherokee Trailhawk
    Hi Les, Certain baseplates can be compatible with multiple trim packages or models but it's always a case by case scenario. Some baseplates might have a chunk of metal that interferes with the trim of specific model or that specific model could have different attachment points than standard models. The Blue Ox Base Plate Kit # BX1138 you referenced is not a fit for a Trailhawk model but Curt makes a compatible option with part # C46JR. The compatible Blue Ox baseplate (BX1136) for your...

  • Items Needed to Flat Tow 2017 Jeep Cherokee Trailhawk Behind Motorhome
    Since you already have your Alpha tow bar with safety cables # BX7380, you'll need only base plates, a braking system, a wiring kit. I recommend the Curt base plates # C46JR, which are a great match to your Alpha tow bar. For lighting I suggest an inexpensive and easy-to-install magnetic light kit like # TL21RK. These take only moments to install and require no cutting into the Jeep's wiring. For a braking system the way to go is the Blue Ox Patriot # BLU37TR which is fully portable...

  • Base Plate Kit for a 2017 Jeep Grand Cherokee Trailhawk 4WD
    I have a solution for you but there is no Blue Ox baseplate kit available for the 2017 Jeep Grand Cherokee Trailhawk 4WD. You will need to use the Curt Custom Base Plate Kit - Removable Arms item # C46JR. This base plate kit will work with Blue Ox tow bars without an adapter. To flat tow your Jeep you will also need: Roadmaster InvisiBrake Supplemental Braking System item # RM-8700.
