On most automobiles, the brackets are mounted within the grille, where they remain not only unseen, but protected from scrapes and scuffs, as well.

Fit perfectly. Straight forward instructions and etrailer videos were a great help. The provided 4 bolts for the upper frame did not fit on the Jeep so just used bolts that had been removed. Product arrived in a timely manner. Delivery service rep was excellent.

no problems, still happy with product

We wanted a very high strength towing system for our Jeep. After completing our homework we did purchase this base-plate for our automobile. My son and I put them on in about two hours time and if you follow the supplied directions was fairly easy to do if you are pretty good with your hands and tools. They are easy to connect and disconnect when in use. I would recommend this product and seller.

This was fantastic. Everything I needed to wire factory lights on my Jeep to the trailer plug on my RV. Quality products at a good price and prompt delivery. NICE!

Ordered the EZ4 Base Plate Kit for our 2015 Cherokee Trail Hawk on July 17th, it shipped on the 17th and we received it on Jul 21st. Worked with Jean P @ etrailer, who was great to work with, for verifying the correct kit and getting it sent. Haven't got it installed yet, but parts look well made. Will recommend etrailer to our friends.

First I have to say that I have never worked with a better company than yours. I ordered the products early on a Sunday morning and received an email stating that the order was shipped that very night. You folks give very good customer service. You answered questions that I had before I made my order and your answers were right on. This kit was the one that I most dreaded to work on, mainly because of all the dismantling I had to do to the car. After watching your videos a couple of times and following the instructions exactly, this was the easiest project that I have done yet to my tow vehicle. I took be about 4 hours to install this and it was a very easy task. I want to thank you for the time and effort your company has put into making the installations of your products very easy. I will definitely be doing business with you again and will advise friends and relatives to do so as well.

Perfect fit on my 2016 Cherokee Trailhawk. Easy installation after getting over having to disassemble much of the front of the new vehicle.

This was a straightforward install. The instructions were easy to understand and follow. All the necessary parts and hardware were included. It is pretty well hidden once installed. I highly recommend this base plate and etrailer.



by:

great fit. a slight cut needed to be made in the bumper bracket to facilitate the round tube to fit through the bracket. but, other than that, it was an easy install took about 2 hours if you include the coffee brakes. this part is highly recommended. Fast shipping. the beast human service. thank you.

Had Base Plate installed today, shop gave me 2.5 hr labor time. I returned just under 2hrs and they were backing my car out the shop. They parked it facing me. I told the Mechanic "That was quick" He said that's because it wouldn't fit. I was disappointed and asked what do I owe you for your labor> He laughed out loud and said it on there, but hard to see. I was so surprised and pleased you have to just about get down on your knees and bend down to see it. took me about 8 min to install everything and connect it to the Tow vehicle. I'm very pleased with it.



by:

Working great on my Fiat 500l with the automatic euro transmission. Towed over 10000 miles and was easily installed using etrailer video instructions. Yes you can tow a Fiat 500 with the automatic euro transmission. The firmware was flashed on a recall and revised in the manual. Most dealers don’t even bother checking for the latest version.



by:

So far has performed very well. Was easy to install and hookup is pretty quick and easy. You install instructions were very thorough. Practically invisible when not in use. Tried to attach two pics, but would only take one.



by:

Ordered Product on Saturday afternoon, delivered on Wednesday, Installed on Friday. My 23 Wrangler Sahara 4Xe did take the spacer and washer on each side of the frame and was no problem getting them to fit. The lower passenger outside nut that holds on the bumper will not tighten down all the way, the flange of the factory nut gets caught in a slot in the base plate on that side. Will look into a standard nut to see if that will work - it is tight against the slot and holding.



by:

Super-cool. It's been a year. I installed it myself and it was way less of a task than I expected. The fitment of this was incredibly spot on (no "tweaking" or drilling). Performance wise . . . it does what you expect. You insert the removable "arms", clip in onto your tow bar, and when you get to your destination the vehicle is still attached to your tow bar. Quality product.



by:

I’m always extremely satisfied with Roadmaster products. I had just bought a new truck and planned on towing it so I needed everything to get it ready to tow. This review also applies to to the other items I purchased.



by:

Good fit, works well. Very happy with the base plate after 1st year of use.
etrailer staff was very helpful with my questions, making certain I got the base plate that was right and advice with minor problems I had with installation.



by:

I installed this kit on my 2015 Honda Fit. The instructions are very good, however, there are a couple of "snags" to watch out for. You might have to enlarge the holes on the blind hole part of the bumper installation in order to get all of the mounting bolts to align. The other recommendation I have is NOT to use the Loctite "red" thread compound on the blind hole bolts where you cannot get a wrench on the inside. The Loctite will dry too fast and cause issues tightening the bolts on those areas. They have lock washers anyways and you can use the Loctite on the bolts you can get a wrench on the backing nut mounts. I have been towing for months now and I am very happy with it, especially the crossbar style. You will have to purchase the crossbar separately. It's more weight and a little clunky compared to the direct attachment but it allows you to disconnect in some tough situations by pulling the crossbar off while one arm of the tow hitch is still attached. I use an Falcon All Terrain tow bar so I can release the tow arms in uneven conditions. And I have encountered all types of uneven ground, it really makes disconnect of the TOAD very easy.

  • How to Flat Tow a 2014 Jeep Cherokee Trailhawk with Roadmaster Stowmaster Tow Bar
    I have a solution for you that will let you flat tow your 2014 Jeep Grand Cherokee Latitude with your Roadmaster Stowmaster Tow Bar part # RM-501, but it will require you to use a Blue Ox base plate kit part # BX1136 and then the Roadmaster to Blue Ox Base Plate adapter part # RM-031. Or you would have to upgrade your tow bar to a set that stores on the tow vehicle like the Roadmaster Falcon part # RM-520.

    We have everything you would need to flat tow your 2015 Jeep Cherokee Trail Hawk behind your motorhome.

In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon 2, # RM-520 . For safety cables you can use # RM-643 . The coiled...

  • Recommended Base Plate For A 2015 Jeep Cherokee Trailhawk With Roadmaster BlackHawk Tow Bar
    We actually have two options for base plates on your 2015 Jeep Cherokee Trailhawk that are compatible with your Roadmaster Black Hawk tow bar. First is the # RM-521446-4 that will connect to the crossbar at the end of the tow bar and looks to be how your last base plate was attached. However, we also have the # RM-521446-5. This will not need that crossbar and will actually attach directly to the fittings on the ends of the arms. This is the easier way to go and is the one I recommend....

    The base plate you can use on your 2017 Jeep Cherokee Trailhawk is the Roadmaster EZ5 # RM-521446-5 and this will work fine with your Falcon 2 tow bar # RM-520. The EZ5 base plates will be slightly easier to install than the EZ4 model # RM-521446-4. Both base plates work on the Cherokee Trailhawk without Active Air Shutters.

    If you have the Roadmaster Crossbar-Style Base Plate Kit # RM-521446-4 on your 2015 Jeep Cherokee Trailhawk you can use the RoadMaster Base Plates to Duncan Adapter # RM-038. If you have the Roadmaster Direct-Connect Base Plate Kit # RM-521446-5 you will need new Arms # RM-ARMS to change it to the crossbar-style arms. I do recommend checking the condition of your tow bar to determine if it will need any repair. Depending on if the tow bar needs any repair it may make more financial sense...

Your best option for towing your Jeep will be to use a tow dolly like the Roadmaster # RM-2050-1. This will allow you to tow your vehicle without installing a tow bar or base plates.

    I checked with Roadmaster just now and for your 2016 Jeep Cherokee Trailhawk the # RM-15267 is a confirmed fit and would work well for tow bar lighting. For a base plate kit you would want the part # RM-521446-4 which is a confirmed fit. Then the most popular tow bar is the Falcon part # RM-520. The SMI DUO part # SM99251 would then fit the vehicle as well. I attached an install video that shows this in a similar Cherokee as well. For a charge line you then would want the part # RM-156-25...

  • Is a Brake Light Relay Required when Flat Towing a 2017 Jeep Cherokee and Air Force 1 Braking System
    Whether or not you need the brake light relay # RM-88400 for your 2017 Jeep Cherokee depends on the lighting kit you are using. The # RM-88400 relay is not required when using magnetic tow lights. With any other type of lighting kit you will need the relay. A brake light switch kit is different than the relay. You do not need a brake light switch kit for the 2017 Jeep Cherokee and that may have been what customer service meant.

    No, when you are flat towing a vehicle like your 2017 Jeep Cherokee the vehicle's odometer will not keep track of the miles just as if you were driving the vehicle. On newer vehicles like your that have digital odometers nearly all of them do not accumulate miles when being flat towed.

  • Can Factory Tow Hooks Be Re-Installed on Jeep Trailhawk When base Plates Are Installed
    To answer your first question, the tow hooks are removed when installing base plates and cannot be re-installed because the mounting holes for the tow hooks are used for the base plates. You could remove the base plates and then re-install the tow hooks but that would certainly be a hassle. And, red Loctite is used on the bolts so removing them would be very difficult. Your second question depends on the tow bar you have for your Jeep. There are several different tow bars and base plates...
