Aries ActionTrac Motorized Running Boards with Custom Installation Kit - LED Lights - AA3048321

Average Customer Rating:  4.5 out of 5 stars   (72 Customer Reviews)

ActionTrac motorized running boards automatically deploy a second step as your vehicle's doors open and retract when the doors close. Integrated LEDs and obstruction-sensing smart system enhances safety. Easy installation with custom fit kit.


Several concerns with this step. First is the design: The concept of two steps is so you can use two steps. However, the position that these rails attach to the truck makes them near level to the truck floor board which makes this step near useless. The second (lower) step is undependable when deploying and the angle at which it deploys means you have to step past the first to get in or out of the truck. So weird. This creates an awkward angle when getting in and out of the truck. When installing you must ensure the magnets are lined up perfectly. Even the slightest misalignment causes the lower rail to malfunction. The advertisement says these are maintenance free. This is not sure, you must routinely use a graphite lubricant on them. One step literally fell apart and they had to send another. We soent hours on the phone with their support team trying to diagnose why the seconds deployed erratically. The LED lights were a huge problem and turned on and off at intermittent times, even when parked. Very distracting for the neighbors. The third set of lights finally seem to be functioning correctly. When all said and done, after all the issues, they seem to be working fine, but again, the angle on which they deploy are not functional. If I had it all to do over, I’d never buy a deployable running board. They’re just a electric maintenance mess.

2022 Ford F-350 Super Duty

I have to say I was a little bummed when UPS showed up with my running boards and the box was destroyed so I refused delivery called etrailer up they said no problem and my new ones were here in 4 days, on a Holiday weekend mind you, customer service is second to none I highly recommend purchasing from etrailer


I installed my new motorized running boards on a new 2021 ford f150 power boost (hybrid).
I had the Amp steps on my last truck and they worked great for 10 years.
When I upgraded to the new f150 I looked at AMP for new steps. They are not available for the hybrid.
I found the Aries and I like the look and love the idea of not having to chop up my wiring harness in a brand new truck!
I started the install with the wiring harness. It was a breeze everything fit and was easy to identify what it did and where it belonged. Then things went south quickly. The nuts and washers from the kit are HORRIBLE! I don't know where they are manufactured but it was on par with the worst off shore junk I have ever seen. The 3/8 washers are so oversized the nuts barely make contact with them.
The nylon lock nuts are so tight I busted off one of the studs on the running board. I am not sure if it is a change for 2021 but Ford has M8-1.25 studs not 3/8 for mounting the boards.
I ended up throwing all of the mounting hardware that came with the steps it the trash and using my own.
The boards are top quality and solid as can be. The fit and finish is perfect.
They look great on the truck. But all I can think of is why cheap out on the nuts and bolts!
I like the boards. and am happy I bought them but It was a long instal due to horrible hardware.


They make a very loud clank when they c lose.


Awesome steps and etrailer is fast shipping and excellent service I have ordered from them multiple times and will continue too


I liked the idea of a two step running board. My wife has had operations
on her knees and was difficult for her to get into her jeep with the
standard side steps. I started looking for powered steps and these
sounded like just the ticket. There was some fabrication involved,
because I installed them on a 2000 TJ Wrangler, but nothing too crazy. I
used some 3/16" flat bar and sandwiched it between the body mounts. In
retrospect, I should have used C channel for the longer front mount,
because I had to weld gussets on it. Welded a piece of angle to the
flat bar for the supplied mounts. If you don't have a welder, it could
all be bolted in with the C channel.
I also didn't care for the supplied magnets and switches held on with
tape to operate the steps. We hit up the u-pull-it wrecking yard and got
the same style switch that operates the dome lights and I installed them
above the original switches.
I put the door delete bypass in the housing for the front speakers on
the dash.
They have been installed for about two months now and we've had no
problems with the operation. Lots of likes from our friends who see them
in operation.


4.5* actually. Overall, I really like these. They are a good price and they look nice. Some of the brackets had to be bent a little bit to get them to line up correctly, but it wasn't bad. I've actually purchased these twice! I sold the first vehicle, but immediately bought these for the better optioned vehicle I traded up for. NOTE - DO NOT buy the door delete kit that can be added to this. It's a waste of money that overrides the basic automatic functionality on a daily basis. The basic kit includes an on/off switch already.


Very good steps, but the light "flickers" on/off on 1 side and stays on all the time on the opposite side! Doesn't really matter because they aren't bright enough to help in the dark!


Steve with TekRV, a mobile RV mechanic, out of Galveston did the installation. Everything went according to the instructions. Looks and works great. Co-pilot is happy, I am estatic.


Excellent product overall. My 22 ram 3500 4 x 4 has an entrance height of 30 inches my wife is 4’9” and can’t get Into the truck without them. As you can see the steps drop immediately when you open the door and have it delayed after you shut the door excellent design.

The only negatives are ran into on the steps, are the LED lights lenses fall off then they short out and stop working. I think this is a Supply problem that can be addressed from the vendor that supplies the LEDs my fix was a sealed the LED lenses to the LED body with clear silicone. this lasted for six months.. The second problem is you have to open the door to clean the bottom step.

The first step is 9 inches from the ground. The second step is 18 inches from the ground and the cab entrance like I said is 30 inches

Installation was not easy by myself, but I got it done wiring is straightforward. Take your time. Buy a tube of clear silicone for the lites and seal the lenses and wire inlets before installing and I think the lights will last a bit longer.

This was my last purchase from etrailer because of a policy within the company they shipped me, returned steps and charge me for new price. Took a bit of back and forth to get what I paid for but the matter was resolved.. .


best looking running board! the ability to step on it to access roof rack is amazing and there is only one other competitor that does that. THIS IS NOT A ROCK SLIDE! But as a certified mall crawler this is great for the ladies and kids jumping in


The running boards have worked perfectly. the closed height is unobstructive for normal 4x4 use and the down position makes entry and exit easy even for persons with dexterity problems.
the light package is adequate for front and rear doors.
Installation went well, leave all bolts loose until mounted then tighten seems to make it easy.
I would highly recommend.


Seems like an excellent product. Etrailer makes things so easy, great software, terrific customer service and reliable shipping.


They are working as advertised, which is good for an old man. Service after the sale was great.


Great product. Good fit, runs well with the body lines. Very clean install.


I order these for my 2022 Chevy 2500 they had them is stock and came fast. Very good fit bolted right on. It took me about 3 hours in my driveway to install them. They are about 12” off the ground when deployed. I like the 2 steps design very helpful. They look very nice and are built strong.


Fantastic product
Got running boards
on and went very easy and I’m 71 years old
Going to tackle the wiring harness this morning


The running boards arrived sooner than expected and customer service is great. The website could be better to see and understand what exactly you’re buying. Haven’t been able to install them yet, had to order extra parts. Downgrade one notch due to website.


Running Boards are exactly as advertised. Simple to install as long as you follow the instructions.


I really like them, the snow and ice sometimes stops them that's understandable and the lights don't always work I haven't looked at them yet but yes we love them thank you


These steps work very well. The installation of the bars are one of the most easiest I have seen. I have installed other brands and they took much longer. All the holes lined up as expected. The wiring is not for the faint at heart. We had to take the back seat out of the Colorado and peel back the carpet to run the wiring. The instructions were straight forward and easy to follow.
After owning these for a year they are still working like the day we put them on. We have had a few issues with the end caps of the walk boards being faded by the sun and turning white. The driver side light began blinking when the door was opened. I contacted the company and they sent me new end caps, stated that they had a bad batch sent to them that were not UV free and they sent a new light. I replaced the light and still have the problem. But the company appears to work well on warranty items. Only reason I did not give the the full 5 stars is due to the end caps fading and the light began blinking. Other wise I would purchase these again. They are not cheap by any means but are of a good quality.


I finally got them installed and they are wonderful. My wife has arthritic knees and it was very difficult for her to get in the Jeep. With these Motorized Running Boards she can now get in effortlessly.


Perfect fit and super easy to install.


Look good, functions well but an extremely difficult install.


I am very happy with the steps with one exception I'll mention later. The Aries fore and aft action was perfect for our 2020 Ram 3500 chassis cab. The steps look great and were easy to install with running wires and locating the processor taking the most time. My only complaint regards the led step lights. Both began flickering then failed completely, the driver side after about six months and the passenger side in the last several weeks.

  • Are There Retractable Running Boards for a 2020 Ford F-250 SuperCab
    The only retractable running boards we offer for a 2020 Ford F-250 SuperCab are the Aries ActionTrac Motorized Running Boards part # AA3048321. I am not aware of any such option which attaches to the factory running boards.

    Although we do have an Aries ActionTrac that will fit a 2022 Ford F-250, the # AA3025165 is not a fit so no mounting brackets are available. Also, the mounting kit is required for installation. The Aries ActionTrac Motorized Running Boards with Custom Installation Kit # AA3048321 will fit if you have the crew cab model of the 2022 F-250. Otherwise you would have to use standard running boards like the # AA4445028 for a regular cab or # AA2558012 for the SuperCab.

    Aries only offers the ActionTrac Motorized Running Boards # AA3025179 as a set. This is just for the boards and does not include everything you get with the Kit # AA3048321 for your 2019 Ford F-250 Crew Cab.

  • Can Aries ActionTrac Running Boards Be Integrated With Factory Running Board Wiring on 2022 F-350
    According to Aries, this may be possible but it is unlikely it would work. It would also void their warranty. Aries has never tested this, and it sounds like it would be more of a hassle than it is worth with a need for additional relays and other components. For that reason using the sensors that come with the # AA3048321 for installation is recommended.

    I feel the Aries ActionTrac Motorized Running Boards # AA3048321 are the best running boards we carry for your 2024 Ford F-150 SuperCrew.
