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.

These tuck nicely under the truck out of sight, high quality product, really prefer them over the other brands have used in the past. I like that the inserts can be removed vs a fixed base plate, like some other brands.



by:

This was a quick install on my 2011 Wrangler Rubicon. Contrary to the Q&A advice that the c38FR (Curt 70102) base plate does not fit the Rubicon with the base stock Rubicon bumper, it indeed does fit. The base plate tucks up within an inch or so of the bottom of the bumper. Base plate C33FR (Curt 70110) recommended by eTrailer and Curt for the stock Wrangler Rubicon would hang down 4 inches below the bumper and would not be a great look!



by:

2024 Bronco Big Bend with "capable" steel bumper. I used an angle grinder to cut two about 3"x6" openings for the hooks to stick through the steel skidplate. Unsure how it would work with the plastic one, but this worked pretty well and allows the D rings to stay which was my personal preference.

High quality and easy to install...

Until I busted the welded on nut off while attaching the skid plate, as it seemed to be a standard vs. metric thread. THe skidplate bolts will not work, new bolts must be purchased to attach the skid plate as they were not provided in my kit and the instructions make no mention of this issue. I located some standard bolts I had on hand that solved the issue in an effective but ugly way. Very disappointed as I'll have to R&R one side if Curt provides a replacement, and find black in color bolts to match the skidplate factory look. So, beware the skidplate threads... otherwise lovely.



by:

Works just like the video with the green Jeep shows you.
The hardest part was getting the outside nuts off the bumper.
Use long extensions and a swivel and a short 18 mm socket.
Other than that it went smoothly. But my friend has a lift so it was a lot easier to do it all baseplate , wiring, and brake buddy cable.



by:

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



by:

Easy to install. All the holes lined up. Vey happy with my purchase



by:

I'm very happy with everything I buy are very professional and they have very good products at very good prices, thank you



by:

Product worked great! Installation was not that difficult, but instructions were xeroxed causing pictures to be difficult to see detail. I was able to go online and see full color pictures with the ability to zoom in. Took about 2-2.5 hours to install



by:

Installed the Curt Custom Base Plate Kit (#C64ER) onto my 2019 Ford Ranger XLT FX4. Could not have been easier. Directions were excellent! Time required was about 2 hours. Great product!



by:

Great tech advice finding the right product, easy purchase and prompt delivery!! Thanks Etrailer!!



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.



by:

No issues, easy installation. Great tech support.



by:

After a little help from a friend and a little bit of cutting on the car, everything worked out great!



by:

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.



by:

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.



by:

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.



by:

It preforms as designed. I tow a jeep gladiator with a 32’ class C RV



by:

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.



by:

Custom fit, everything went together smoothly. I'm ready to haul my Ford ranger behind my motor home.



by:

Great product and service this my second setup I have purchased. Very easy to navigate for what you need.



by:

Quality product overall with good installation instructions.



by:

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.



by:

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



by:

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

  • 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...
