The Carr side steps are well designed, well engineered, and well manufactured. The kit comes complete with all the necessary hardware, and the instructions are clear and easy to follow. Overall, I found them quite easy to install. Only time will tell as to their durability.

2023 Ram ProMaster 1500

These fit better than I initially thought on a 2023 Ram Promaster High Roof 136 van. The instructions that came with the steps could be tweaked a bit to make things easier but I watched the installation video on the etrailer page with helped a lot. The steps are lightweight but strong - great help in getting up into the van. All the hardware was included (and accounted for) and the design and install method should last for quite a while. I did paint the holes in the pinch weld after I drilled them as this can be an easy spot for rust to occur. Overall I am very happy with the initial install, sturdiness and look of the steps.

2016 Ram ProMaster 2500

These were a perfect choice for our 2016 Winnebago Travato 59G. Not a lots of skill required and they look great. Very nice product. Thank you for the fast service.


I purchase these for my Kubota tractor and they did the job for me. Substantial and well made. I did some modifications but I am please with the steps.



Still does the job. It makes getting on and off the tractor much better

2015 Chevrolet Colorado

I'm delighted with the final product, but the installation did not jibe with the video for my 2015 Chevy Colorado, nor with the enclosed instructions. I spoke with Bill (ext. 377) at tech support and described the problems. There is no access space to install the upper screw at each bracket, so I had to "re-invent the wheel," by making and attaching steel straps at the bottom of each spacer tube, attaching them with self-tapping screws. There is also a box shaped steel shape that is in the way of installing the brackets in the so called ideal location. I'm now pleased with the installation, but shouldn't have had to go to the trouble I did.

The black finish has completely disappeared the steps are now a grey oxidized color ugly. I guess someone needs to figure out a better way to finish the aluminum.

2020 Chevrolet Silverado 1500

I installed on a Promaster 1500 Van. The install went pretty smooth. Probably would have written a few steps in a slightly different order. Also, wish the step protruded outward a little farther. It is perfect for the step up, but difficult to find on the step down, and even maybe a little too easy to accidently trip on it. But it is a nice looking step. Sturdy. Instructions easy to follow. And delivered on time with all the pieces in fine shape.

2017 Mercedes-Benz Sprinter

Mounted these on a four wheel drive sprinter to make getting in and out easier. Installation was easy enough and straight forward there is a video online that is worth watching a few times to clear up any confusion on how these mount. I used the short spacers on my vehicle but found that customizing the length made for a more solid connection to the vehicle. A belt sander was the best tool for that. You should probably have a primer at hand to deal with any exposed steel.


This was recommended on a van life group page to add a step to passenger doors. Easy to install and good quality, solves our issues with getting into our seats.


Hello Donna your product looks great and also strong made. We haven't put the hoop step's on the SUV yet. With that being said I'm sure the steps are going to be fine.
If not the SUV, we have a few more automobiles these great looking black hoop steps will fit. Thank you Donna and etrailer for making our product shopping easy and Pleasant. We will order from again. Thank you Donna

2017 Ram ProMaster 2500

I installed these on my 2017 promaster and I’m an amateur at best but the video was a big help . They are a solid and help stepping up in the van but getting out you need to place your heel just right . Looks good too.


These make entering/ exiting my Promaster van so much easier! Just wish they stuck out a bit farther.

2018 Ram ProMaster 2500

Fit and finish are excellent. Easy to install do exactly what I expected, making ingress into my Promaster Van much easier. Arrived ahead of time. Give them five stars.

Mercedes-Benz Sprinter

Great product and easy to install on my Sprinter RV


worked fine but went over a kelly hump in the mountains and snapped both steps off! The mounts were fine so I reordered and replaced them (I know now to take them off before heading to elk camp) Just the thing for my height-challenged wife to get in my work van.


I just received this item yesterday. I opened the item and is what was advertised. Quality appears decent.

2023 Ram ProMaster 1500



2022 Ram ProMaster 1500


Just as described and quick delivery!


Product was as advertised.


2021 Ram ProMaster 1500


Originally ordered these as a replacement for the front. Did not check size before ordering.
Decided to put them under the rear doors instead.
Since I already had them on the front and was able to see how they were mounted, it made the install was a piece of cake.
The instructions were clearly understood for my Silverado and only took me about 15 minutes per side to install.
I have since ordered the larger pair for the front and will use the same brackets to replace.
Only gripe is the finish on the ones that were originally on the truck (8 years old) has chipped off due to mag chloride on the road and frozen ice being knocked off.
Since I was not the original purchaser, I cannot claim warranty issues as they are guaranteed for life.
Hopefully with the new ones Carr perfected their coating, we will find out in another 8 years!


why are they called Nerf bars? none of my other Nerf stuff looks like that.....

  • Is There an Individual Carr Step for 2022 Ram ProMaster 2500
    Carr does not offer their step part # CARR105771 that you referenced individually. Only option would be to order as a pair and either store the extra one in case you were to damage the one installed or just install both.

  • Does CARR Side Steps # CARR105771 Fit 2012 Ram Express
    Yes, the CARR side steps part # CARR105771 that you referenced are a confirmed fit for your 2012 Ram 1500 Express. We had the chance to install them on a 2012 Ram like yours and we found that they fit and worked well.

  • Carr Custom-Fit Side Steps That Fit a 2017 Ram ProMaster 2500
    We do have Carr Custom-Fit Side Steps that fit your 2017 Ram ProMaster 2500, but it is the 7" Set # CARR105771 as opposed to the 17" Set # CARR125771. If you think you will be able to get the 17" set to fit then you are more than welcome to try, I just can't guarantee a fit with the longer steps.

  • Carr Custom-Fit Hoop II Side Steps for 2018 Ram 2500
    The correct Carr Custom-Fit Hoop II Side Steps for your 2018 Ram 2500 is indeed the part # CARR109771 that you see on Carr's website. This is confirmed to fit your truck and they can be mounted along any of the doors for your Ram. The Carr Side Steps # CARR105771 that you referenced are designed for certain model years of the Ram ProMaster, Dodge Sprinter, and Mercedes Sprinter Vans. The mounting brackets simply won't match up well to the rocker panels on your Ram 2500.

  • Could CARR Side Step Hoop II Fit 2015 Ford F-450 Cab and Chassis
    While the Carr Custom-Fit Side Steps # CARR105771 wasn't custom fit for your 1994 Ford F-450 it could definitely be installed on your truck. It's a universal style install that can easily attach to the underside of your truck and help you get in and out.

  • Recommended 7 Inch Steps for a 2023 Ram Promaster 2500
    We currently do not have an option for a 17" step on the 2023 Promaster 2500's so your guess would be as good as mine. We do have a 7" step that has been recently reviewed by a customer. It is the Carr Custom-Fit Side Steps item # CARR105771. These custom fit steps attach to your ProMaster with included hardware. They are made in the USA of cast aluminum that has been powder coated for durability and rust resistance. I have linked an installation video below along with a screenshot...

  • Availability of CARR Single Step that is 17 inches Long to Fit 2018 Mercedes-Benz Sprinter 2500
    Basically the difference between the two CARR steps you have part numbers # CARR125771 and # CARR105771 is the length of the step. The mounting brackets are the same. The CARR125771 is 17 inches long and the CARR105771 is 7 inches long. We do offer a 17 inch CARR step sold individually as the part # CARR124031-1.

  • Recommended Side Door Step for 2018 Ram ProMaster 2500
    At around the 1:40 mark on the attached installation video for # BBS-1103, you can see that the Bully Black Bull Side Steps mount on a little over 8 inches on center. These are designed to fit a wide range of vehicles, but your 2018 Ram ProMaster 2500 isn't one of them. We do have one custom fit solution to add a step below the sliding door on the side of your ProMaster with the Carr Hide Away Step for Work Trucks # CARR501090. The really nice thing about this step is that it's designed...

    I did some online research and your 2022 Ram ProMaster 2500 is compatible with the Carr Custom-Fit Side Steps - Hoop II - Black Powder Coated Aluminum - 7" Step - 1 Pair, part # CARR105771. Drilling will be required for the installation of these steps. I did some online research and the Carr Super Hoop, part # CAR54GR, does not fit your 2022 Ram ProMaster 2500.

  • Best Side Steps for Clearance and Stepping Area on a 2019 Mercedes-Benz Sprinter 2500
