Need Running Board Mounting Brackets For 2014 Chevy Express 3500  

Updated 09/29/2025 | Published 05/01/2025

Question:

Hi, I need some mounting brackets to mount some existing running boards to my 2014 Chevy express 3500 long wheelbase base. The brackets do t have to be running boards specific as I can fabric a little bit. Mounting bracket preferably to mount to the frame and body mount locations but not necessarily. Thank you.

Hello James, thanks for reaching out. The running board options are a bit limited for the 2014 Chevy Express 3500. We do have the Custom Installation Kit for DeeZee Rough Step Running Boards # DZ15316 which is for the 2014 Express 3500. This kit is for the DeeZee Rough Step Running Boards # DZ15300S-15316 which are 7" wide flat steps that go in under the front for. The picture below shows an example.

That will be the only mounting kit we have for the 2014 Express 3500. All of the other mounting kits come with the running boards and are not available separately.

What kind of running boards do you have now? Are they flat steps or more like tube steps?

@JesseM I have not worked on my running boards yet. I will be buying some generic brackets and welding some brackets, probably later this winter.

@JamesS I gotcha. Sometimes the only option is to get creative and fabricate something! Feel free to come back if there is anything else I can help with.
