Features:

  • Hidden bracket design provides improved aesthetics compared with standard brackets
  • Drawbars are easily removable - just twist and pull
    • No pins or clips required
  • Computer-cut, all-steel construction provides exceptional strength

The drawbars, or front arms, on the EZ series base plate kit are supremely easy to mount and remove. Just insert them into the brackets and twist to lock them in place. To remove, simply twist the arms back and pull them out. Once the drawbars have been removed, the remaining brackets are virtually invisible. On most automobiles, the brackets are mounted within the grille, where they remain not only unseen, but protected from scrapes and scuffs as well.

Base plate was delivered on time and in good condition. Directions were very clear and fairly easy to install. My son helped me.Its easier with 2people. The light kit was also easy. We ran the 4 flat wire through the firewall driver side .We found a rubber gromet near the top and popped out. We ran the wire under the plastic trimon bottom of door all the way to compartment for jack to tailight assembly. We drilled hole in bottom circle of light to accept light and then under rear bumper and up other side to right assembly.Wired according to instructions. They work great. I like the ease of taking the hitch off when not in use. Thank you for everything.

I finaly got around to mounting the EZ tow mount on my 2009 Jeep Liberty after receiving it over a month ago. The written instructions were very detailed and I also watched a U-tube video showing the installation on a 2012 Liberty. All the parts were there and every thing "bolted up" as advertised. The only issue I had was a weld on the inside of the square tube for one of the long bolts kept me from getting a socket on that bolt. A littel work with a file and that was taken care of. I have yet to tow the vehicle behind my MH yet but I don't think there will be any problems.

Install them on a 2006 Jeep Liberty , Installation was as explained in directions and not very difficult. However I was both a master auto body mechanic and and above average auto mechanic with 40 years in the trade. I do believe that the average person can handle this by flowing the instructions and using common senses.

Not an easy task of course. I've done a 2006 Liberty once before, so I was somewhat familiar with the installation. The directions were great and installation went well. Only the finder flare rivets were a problem because I did not have a plastic rivet tool and there were none available near here. I had to use vise grips, a pair of pliers with a small grip hole at the end and a foot. Gotter done, Thanks for the prompt delivery. Dan

Review from a similar EZ in Base Plates


Parts came very quickly. The base plates are really well make and of heavy material. If you watch the video it is a breeze to install. Make sure you have some new clips for your bumper as the old ones will break, not all but some. I ordered clips from Amazon. I used a vibrating saw with cutting blade and it did nice job cutting plastic bumper cover.

  • Roadmaster Base Plates for a Sterling Tow Bar and a 2011 Jeep Liberty
    The first thing you are going to want to do is consult the owners manual of your 2011 Jeep Liberty to determine if it can be flat towed or if anything additional is needed to tow the vehicle. From the research I did, all wheel drive models with automatic transmissions and models with 2 wheel drive and a 6 or 5 speed can only be towed on a trailer. Two wheel drive models with automatic transmission will require a transmission lube pump. And 4 wheel drive models with automatic transmission...

    There are two sets of base plates that will fit a 2010 Jeep Liberty. If the Liberty has a rockguard or skidplate but no brushguard, you will need # 521434-1. If the Liberty has no brushguard, rockguard, or skidplate, use # 521433-1. Both of these base plates are EZ models and are compatible with a Sterling tow bar.

  • Parts Needed to Flat Tow 2011 Jeep Liberty with Nighthawk Tow Bar
    For your 2011 Jeep Liberty there are only base plate kits from Roadmaster that require the use of a crossbar like the EZ Kit part # 521433-1 which you have currently. Some vehicles with heavier duty frames allow the use of the direct connect style base plates but this isn't available for every vehicle. Since the Roadmaster Nighthawk part # RM-676 does not come with the crossbar you need you'll need the crossbar kit part # 910021-00 as well.

  • Do All the Base Plates for a 2012 Jeep Liberty Require Removing the Front Bumper
    The base plate options for a 2012 Jeep Liberty all require removal of the front bumper cover.

In regards to the braking system, the Blue Ox Patriot 3 Braking System part # BRK2019 is my personal favorite. The Tow Ready Tail Light Isolating Diode System part # TR118821 could then be used to complete your setup.
