When you’re not towing, the Roadmaster EZ Base Plate Kit keeps the front of your vehicle looking uncluttered. The hidden bracket design tucks neatly within the grille, so nothing sticks out or catches your shin when you walk by. Once you twist and pull out the removable drawbars, the brackets are virtually invisible and protected from scrapes or scuffs.
Getting ready to tow is quick and simple thanks to the EZ Twistlock feature. Each drawbar slides into the bracket and locks in place with a quick twist—no pins or clips needed. When it’s time to disconnect, just twist and pull them out. This twist-to-lock design means less fumbling and a more secure, repeatable connection every time you set up.
This base plate kit uses computer-cut, all-steel construction for exceptional strength and long-term reliability. The black powder coat finish resists rust and corrosion, so it stays solid and clean even after years of use. It’s made to handle the stress of towing while keeping a professional finish that holds up through weather and road grime alike.
Installation is simple and doesn’t require welding. The kit bolts directly to the frame for a secure fit, and comes complete with instructions and mounting hardware to guide you through the process. It’s designed for a precise fit with your tow bar setup so you can get everything aligned and ready without guesswork.
If you already own Roadmaster towing equipment, this base plate fits right in. It’s compatible with all Roadmaster tow bars as well as Quick Disconnects, so you can build on your existing setup without needing extra adapters or new hardware.

Today, on our 2010 Hyundai Elantra, we'll be installing the Roadmaster base plate mounting bracket kit part #521624-1. Now, to begin our installation, we'll need to remove the two 10 millimeter bolts that hold the air intake to the core support. We'll then remove the plastic fasteners up here. Now, we'll work our way down on the vehicle here to the front fender well on the driver side and we'll remove the eight millimeter screw that holds the corner of the facet to the fender. We'll do this on both the driver side as well as on the passenger side. We'll then work our way underneath the vehicle where we'll need to remove the three plastic fasteners on both sides.
We'll now remove the five 10 millimeter bolts attaching the center splash panel to the radiator support. Now, on the inside of the subframe, you'll find two splash seals. We'll need to remove these as well. With those all done, we're now ready to remove our facet. We'll pull outward on both corners where we can then pull it away from the vehicle.
With that done, we'll now cut the air deflectors on both sides to allow clearance for the main receiver braces. With them cut, we'll now remove the two lower bolts that attach the bumper core to the ends of the frame rails. We'll do this on both sides and set them off to the side as they will not be reinstalled. We'll now take the driver side main receiver brace, put it over our bumper core, rotate it ,making sure we take the pipe spacers and put them behind the bracket but infront of our bumper core support. We can then rotate the receiver brace up until it lines up with our holes.
We'll then take the long hole included with the kit and slide it through the bumper support, through our sleeve and back out the support on the back side. We can then put a lock washer on it and finally a nut. On the two smaller holes where we removed the 12 millimeter bolts, we use the bolt flat washer and lock washer, replacing the two 12 millimeter bolts that we removed previously. With those in place here, on the driver side, we'll repeat the same procedure and attach our passenger side. Now, with both upper brackets on, we're ready to move on to the lower brackets.
We'll now take the lower bracket here on the driver side and put it into position where we can run the bolt and flat washer through the bracket, through our upper bracket and finally put a lock washer and nut on the other side. Once we have the driver's bracket in place, we'll take our U-Bolt, slide them around our subframe and back through the bracket. We can then put the washers on and secure it with the nuts. Now, we'll repeat this same procedure for the passenger side bracket. Now, with both lower brackets in place, we can work our way around tightening up all the bolts that we've just intalled, torquing them to specification as indicated in the intructions. Now, with all our hardware torqued to specification, we're ready to reinstall our front facet. Now, before we can do this, we'll need to cut a hole in the facet for each of the two braces. We'll first measure out from the center of the verticle rib. We'll then use a two inch hole saw to drill directly through the center of the horizontal rib. Once we've done that, we can now reinstall our facet. With that done, we can reinstall our lower panels again trimming them to fit our new brackets. That will complete our installation of the Roadmaster face plate mounting kit, part #521624-1 on our 2010 Hyundai Elantra.

I towed my Mini Cooper on a 5000-mile trip this summer. The Base Plates worked great. I had to replace the water pump on the Cooper this required removing and reinstalling the base plates. I inspected them, and after two years and 9000 miles of towing, they are in perfect shape.

The Roadmaster baseplate and Falcon tow bar are working great with our 2014 Grand Cherokee and Endeavor motorhome. We are in the middle of a 1500 mile trip and have had no problems with the equipment. I have decided that I need to purchase a braking system for the Jeep. Thinking about the Invisi Brake, primarily because it is made by Roadmaster and I had a great experience with your companys customer service when the 2014 Grand Cherokee baseplate kit was being developed. Thanks for the good work.

Have been using this tow adapter now for a while and everything works out fine, Easy to connect. I did purchase the Wiring harness from the tail lights to the front of the car instead of making it as I usually do and the connection to the RV from that connection and glad I did, the wiring harness also went easy and very fast.

I have towed my Terrain about 3500 miles with no issues. It tows and tracks extremely well. I put red paint marks on the bolts that are easily seen, so that I can see at a glance if any bolts have loosened up. I use a Roadmaster All Terrain tow hitch and SMI Duo braking system.
