Video Transcript for Roadmaster Tow Bar Adapter Installation - 2015 Jeep Grand Cherokee

Hi, John with etrailer. Listen, if you are already set up to tow like these folks here and they just wanted to add their Jeep to their arsenal of flat towed vehicles, well this is one of the options that you have out there. This is gonna adapt a Roadmaster base plate to certain types of tow bars. This right here is the Roadmaster Tow Bar Adapter on our 2015 Jeep Grand Cherokee. Now to begin your installation, it's gonna be easiest if you have your arms mounted into your base plate. For us today we have a hash mark on the inside.

This is gonna be to the inside of our vehicle and they're gonna be locked in like this. Now we need to get our brackets mounted onto our arms. We've got these up on the table here. So we're gonna pull the pins on each side and we'll have our brackets. Now these brackets are side specific and this is nice when it's brand new, but you'd also need to know once these labels come off, you need to know which side.

We can see this says driver's side of car and passenger side of car. So you just need to remember if you can that we have a flange on the inside and not on the outside. So these are all gonna go towards the inside of the car. We can begin by grabbing a plate, some bolts, flat washers, lock washers, and hex nuts. And that's what we're gonna need to install these onto our arms.

Now we'll grab our driver's side bracket and come to the driver's side arm. On our base plate we'll match these up. Take the bracket that came with your kit, we'll put that there and take your hex bolts and run them through. Then on the backside, take a flat washer on each bolt, a split ring lock washer on each bolt, and then a hex nut. Now keep these loose right now because we're gonna need to adjust these in just a minute when we get the crossbar.

So get this done for the passenger side as well. Now we can take our crossbar. You're gonna notice alignment dowels on the bottom and our hookups on the front where our tow bar is gonna attach to. And set this down onto the brackets. You may have to move them back and forth. This is why we kept them loose. Now the other reason why we kept them loose, you can see how much play is in here. And when you're flat towing you wanna keep this centered as much as possible to reduce wear and tear on your equipment. So the other reason we want this loose and lined up we want this to be easy to take on and off. If it's too tight or too loose, it's gonna be a real pain and that's not what you want when you're flat towing and trying to have a good time out here. So once you're happy with the alignment on your Jeep and the way that it comes on and off you can snug up the brackets to the arms. Now, there's not gonna be any torque values but I do recommend using Blue Loctite and they say you're gonna have two layers of protection there. You're gonna have a split ring lock washer, and Blue Loctite holding these together. It's advisable to check these out once in a while. Make sure they don't get loose on you. Hardware's gonna be 19 millimeter. Now I'm using a torque wrench just to make sure that these bolts are uniformly tight. Like I said, there's no torque specs on here but this is grade five hardware. And so I have a torque range that I'm looking for on this to keep it together. Now with our brackets mounted, go ahead and test fit the crossbar. Yeah, so I'm actually gonna make an adjustment. This one, just by torquing it down it moved it in a little bit. And you may have to do the same thing. It should be able to slip on and off easily. Even though we have movement in the arms it should still be able to go on and off easily. This will drag in just a little bit. Once you're happy with the fit of your crossbar you can lock it in place with the pins. Now you're gonna notice graphics up here are saying yes and no. If you look at these pins, you're gonna see that the ring comes in at the bottom and at the top on the one side. So when these go in, they need to snap down and lock onto the shaft up here. If these go backwards, sometimes this is gonna hang up like that. That's really what the graphic's showing you right there. So you wanna make sure that you have positive engagement every time you do this. It doesn't matter so much if it goes from the left or from the right, just make sure that the ring is touching. That's gonna lock our crossbar into place. Now we can attach the tow bar. Now the adapter comes with pin and clips just in case either yours with your tow bar are worn out or if you just want brand new clips. So that is something that's nice as well. So from here out, you can either unhook your tow bar here or here at the the crossbar. And this was just one way to add a second vehicle to your flat tow list. Make sure you check out our website. There's other ways that you can do it as well, whichever one works for you best. That was a look at the Roadmaster Tow Bar Adapter on our 2015 Jeep Grand Cherokee.

Roadmaster Tow Bar Adapter - RM-032

Average Customer Rating:  4.8 out of 5 stars   (80 Customer Reviews)


I purchased a JEEP Wrangler that was set up for a ROADMASTER towing system. I own a Blue Ox system. So I needed an adapter to make it work. This TOW BAR is just perfect. It fits exactly to specs and I now feel safe towing my new JEEP. I especially like the way your system tracks an order, from the moment it's is received on line to the time it is being delivered in my area. I shows all of the stops and handling that it goes through. It is a great system. I will order from you again in the future and highly recommend your products.


I recently purchased a Roadmaster base plate kit and hitch adapter for my Dodge Ram. It was purchased to replace a Blue Ox unit that had been installed poorly previously. It was easy to install with no frame drilling and only minor alterations. It fits and works perfectly. Rachel at etrailer was very helpful, knowledgeable and patient while I got her the necessary information. I am very pleased and would not hesitate to call them again. Frank S


Here is my 2018 Jeep Cherokee with ALL your parts installed. Tows like a dream behind my Motorhome. All Blue
Ox parts. Sorry for the dirty Jeep, just came back from a trip From NC.


Quick easy process. Received email confirmation of shipping with a follow up email to assure it was received.The bar fit as described and now we are on the road.


Any discounts, I love buying from your company and I promote everything I get...


The Roadmaster tow bar adapter was just what I needed to complete the install of my Blue Ox tow bar. It is easy to attach and remove.


Did not fit the bracket and had to return. The wrong part was identified for my application, even though I clearly stated what tow bar was to be used with this application.

Thank you for reaching out. Our customer service team will be in touch with you.


Excellent service!


I really like using the Demco non-binding tow bar. Hooking up is so much easier with it than our previous tow bar. No need to level and square up the toad with the motor home. I also like having the safety cables permanently attached to the bar.
We changed toad vehicles this year, so I bought a Demco base plate for our CRV. The tow bar shafts simply plug into the base plate. It couldn't get any easier.


I've only used it once but it works great with my blue-ox tow bar.

Richard S.


I have now used it many times and it is still a good choice.


Did not have any issues pulling over 5000 miles


This part has performed perfectly. Easy installation...taking only seconds to put in place and secure. A well built piece for sure has


Works well with the Roadmaster base plate and my Blue Ox tow bar.


I am a big fan of Roadmaster products (I own a 2006 Honda CR-V outfitted with a Roadmaster XL Base Plate Kit with Removable Arms) and this Tow Bar Adapter is no exception. Roadmaster products are designed with quality and ease of use in mind and I especially like the quick disconnect aspect of this hardware. To make things even better, working with etrailer is a pleasure. Their product line is robust and items are delivered in a safe, timely manner and I love the tracking feature.


The installation instructions were clear and easy to understand. Some Miatia bolts broke off when torqued and to be drilled out & replaced. Rubber fasteners had decomposed after 15 years


Product does what Roadmaster said it would. eTrailer is always fast to ship and easy to deal with. Sometimes I wish they would do a better job of packaging for shipment. At times, heavy products are received hanging out of the box. Given they are tow brackets and hitches, it's not that big of a problem.


Fit and finish is perfect. Just what I wanted to replace my Roadmaster Sterling towbar with the Blue Ox towbar I bought as a replacement.


Works fine, would have preferred a tow bar without the heavy crossbar, towbar adapter. Company was excellent to work with , friendly and knowledgeable.


Was as advertised and very easy to install. Worked perfectly hooking up my Blue Ox Aventa II to my Jeep Grand Cherokee with Roadmaster xl base plate


Adapter worked perfectly transitioning from a Roadmaster base plate to a Demco tow bar just as you said it would. Service was great as usual.


The adapter arrived today and was exactly what I needed to connect my Blue Ox tow bar to a Road Master base plate.


Does the job. An excellent way to use a Blue Ox Tow Bar with a Roadmaster Baseplate.


The Roadrunner RM032 tow bar adapter fit perfect on my Jeep Liberty. My Blue Ox works perfectly with the adapter.


Easy install and easy to hookup .


Good, quick, exceptional service, Diana researched my vehicle and tow bar to ensure I got what I needed to ensure my transformation to flat tow a different vehicle was a success. Never had a bad experience with, thanks for the fast and accurate service.
