These running boards were an easy 2 person installation. The added sleeve to fill the gap keeps the side and bottom of doors clean by most of so much easier to get in and out of the truck



by:

Order placed 1/1/24. Received 1/4/24. Two boxes, 1 with running boards, second with hardware, all good. 2 black plastic "J-strips" in long box not included on parts list nor described in instructions (packing spacers?). Broke two square head bolts off while tightening nylon nuts holding running boards onto support brackets - very soft, be careful. Running boards otherwise look great and appear well built. Other aspects of install on 2024 4-Runner were straight forward and were completed in about 75 minutes.



by:

Fit perfectly to replace my damaged running board



by:

VERY happy with the finished product. There were a couple steps not called out in the instructions that I had to figure out*, but once I did... all went together easy enough. First side I installed, the passenger side, took about an hour, and the driver side took about 30 mins.
*First was a trim strip that comes in the box. Had to figure out how to mate them to each running board. Also, on my wife's 2023 4Runner, there was a small (~2" x 5") piece of plastic in front of each rear wheel. My hunch is that it's to protect against stuff getting flung up. Had to remove those from each side to make room for the running boards. Once removed, all just came together easily.



by:

It was easy to install. Had 2 extra parts in box that the instructions did not cover. I called the 800 number and the person new what I was talking about right away. He explained where it went and how to install it. It only took me and a helper about 45 minutes to install.



by:

The runningboards that where installed a year ago are still looking brand new. It made a great addition to my Explorer, not just for the look but for the practical use. My wife who needs that extra step is grateful. etrailer did an awesome job helping picking the right product for my vehicle, the sale and installation.



by:

I really like these runningboards. They look great on the truck they were nicely. Everything is good.



by:

Love it but it was missing one bolt for the running board M 8 square head bolt



by:

Not only stylish but worked perfectly for the lift application for my handicap wife



by:

Arrived 1 day early. Installed it in less than an hour and a half. Looks fantastic. Did not have to drill any holes. Simple bolt up install. Instructions were okay , would suggest using the [online] video- very helpful. Looking to now order a hitch



by:

Great product and easy installation. It only took about one hour to install these and they look great. Perfect fit for my 2019 Colorado.



by:

Kit was delivered promptly. Installation instructions were clear. There was even a note in the instructions about excess paint likely to exist on specific frame bolts. My only suggestion in this case would be to use a die to clear the threads. I purchased one separately to fix this issue. I could not get the nuts on otherwise, and I didn't want to strip the threads.
Other than that hiccup, installation was a breeze.



by:

I recommend this running boards. If you are determined you can install by yourself. It took me approximately 1.5 hours for each side.

Overall looks good and helps with the kids.



by:

Easy to install, look great. Another trouble free order. Keep it up and I'll be back



by:

They need another brace that I will make. The rear mount flexes the metal on the cab. Fit good but not real sturdy.



by:

easy install & look great !!!



by:

GREAT Product! Price was perfect. Fits well, looks like OEM and actually looks better than the Ford sidestep (non electric).
Needs: perhaps a little wider and a taller gap from step to door. My foot slipped a few times on entry and on exit, not much room to step on. That is my only grip....Overall and outstanding product!



by:

Good fit, love the design and contour.



by:

Quick delivery. Extremely nice running boards and easy to install. What a difference they make on my 4runner. Thank you for your service.



by:

Good quality. Definitely recommend a second person just to give a hand and check to make sure it's even. Very sturdy and decent amount for stepping on and off.



by:

Looks great on my 2019 Ford Explorer. Easy installation, took me and friend 1.5 hours without lift.



by:

Looks great ! It could have been awesome if it’s in chrome , to match the vehicle’s trim .



by:

Customer service was great and product arrived before expected date.



by:

They fit and work great. Easy install.



by:

It has been 1 year since I installed my Running Boards. I Love them. They were very Easy to install and They Look Great. But the Best Part was that Christina Helped me to get Proper Brackets to Make the Install Happen. What a Company
