Features to know about

Built for a Clean Look: Partially Hidden Bracket Design

When you remove the arms, the remaining brackets are tucked in tight and nearly invisible. The base plate mounts within the grille area, so nothing bulky sticks out and the front end keeps its clean, finished look. That also means fewer bumps or scrapes when you walk by or hit the trail without towing gear attached.

Quick Hookups Without Guesswork: Twist-Lock Removable Draw Bars

Each drawbar slides into place, clicks to lock, and secures with built-in pull rings for easy unlock and removal. There’s no fumbling with pins or extra tools—just twist to connect or disconnect. It’s a simple system that makes solo hookups fast and dependable whether you’re packing up for a trip or unhooking at camp.

Solid Build for Long-Haul Confidence: Computer-Cut All-Steel Construction

Every bracket is computer-cut from steel and finished with a black powder coat that resists corrosion on long hauls. The design bolts directly to the frame and spreads pulling forces evenly for a strong, stable connection through thousands of miles of towing. No welding is required, and all mounting hardware comes in the box for dependable strength right out of the gate.

Works Seamlessly with Your Setup: Crossbar-Style Compatibility

This kit provides attachment points for a quick-disconnect crossbar (910021-00, sold separately) used with Roadmaster tow bars or required when running a Sterling tow bar. Once installed, it integrates cleanly with your existing towing system so you can keep using your preferred tow bar without reworking your whole setup.

by:

well I finally put my tow bar base plate on. I'm 82 years old so I had my doubts as to weather I could do this so I checked out a location that could have one this job for me but they wanted a hundred and fifteen dollars an hour labor so I said to hell with that . I looked at the directions that you sent with the Base Plate and said to myself, I can do this. Well I did it. Your instructions were dead on and I had no problem at all, In fact I hade a little fun doing it. Thanks a lot It's going to be great.

I am not quick to review a product, it's been over a year since I purchased and install this hitch.
After using this for a year, I found this to be excellent.
Absolutely no problems.
My wife and I installed it with no problems at all,,, easy to do.
The videos was detailed, letting feel comfortable in doing the job.

Sadly, selling the vehicle,, now we don't have it any longer.
However,,,
With our new vehicle, I am again going to purchase from this same company.
This fit our 2004 Jeep Wrangler X



by:

The Jeep project went very well everything fit great and worked well. I really love Roadmaster products and quality and your company is the best place to purchase them. I sold the Jeep and replaced it with a new 2019 Chevy Equinox 2.0 L AWD and just purchased and installed the following items from you and installed them, RM-156-25 & RM-156-75 Battery Charge Line Kit, RM-146-7 Flex Coil Kit, RM-523193-4 EZ4 Plate Kit, RM-88333 Custom Seat Adapter, RM-751489 Stop Light Switch Kit and a RM-98160 Second Vehicle Brake Kit w/brakeaway. All these parts were in stock and arrived quickly and normal with you people, I really enjoy the o-line vidios as I do all my own installs. Thank you so much for your great service.
I will attach pictures of my install, you will see how I was able to fab a bracket and attach it to the existing mount on the base plate to mount the brakeaway switch and the air connection for the brake system.
I also fabricated a tail light bar as I didn't want to use mag-lights or splice into the factory lights and bulbs installed into the lights would not work as the factory brake lights will come on when the brake system is applyed and the turn siginals would not be visable.
Thanks for all you do, I would and do recommend you people to everyone who needs your products. Rob

These are great products, everything fit perfectly and performed perfectly. Thank you for great service and great products. Rob

  • Can a Jeep Wrangler be Flat Towed by the Front Bumper
    I have a solution for you, however, I would not recommend mounting a tow bar directly to a bumper on a Jeep, whether it is OEM or an aftermarket bumper. Jeep does not recommend towing the Wrangler with the OEM bumper because it was not designed to pull the weight of the vehicle. Also, mounting a tow bar to a bumper would require drilling. I spoke with my contact at Pavement Ends and she said drilling into this bumper would void the warranty and they do not recommend using it to tow the...

    I am happy to help you find the parts to flat tow your 2004 Jeep Wrangler. The Roadmaster Direct-Connect Base Plate Kit part # RM-521424-5 is a better option for a base plate compared to the Roadmaster # RM-521424-4 that you referenced because the Roadmaster Direct-Connect Base Plate Kit doesn't require you to leave the crossbar of your tow bar on the base plate to use the quick disconnect like the slightly older version.

    The Replacement Quick Disconnect Crossbar Assembly part # 910021-00 is designed for use with Roadmaster Crossbar-Style Base Plate Kits like part # RM-521424-4 which is a fit for your 2005 Jeep Wrangler so I cannot recommend that you attach this directly to what I presume is a metal bumper.

    From what I was able to find in the owner's manual of the 2000 Jeep TJ Wrangler, you're not supposed to tow the vehicle on a tow dolly that leaves only 2 wheels on the ground (I do believe it's because of the transfer case). You can either flat tow the vehicle or tow it on a trailer/dolly that keeps all 4 wheels off the ground. In order to flat tow your TJ you'll need base plates, a tow bar, tow bar wiring, safety cables, supplemental braking and in most cases, a high/low adapter. I've...
