Does The Westin Sure-Grip Running Board Kit W73FX Include Everything Needed For The Install?  

Published 11/10/2026

Question:

Hey guys. Im looking at the Westin Sure-grip running boards. PartW73FX. Per the description it has what I need to mount it, but at least one comment said it didnt come with all the required parts. Do I need anything else for my 26 Sierra HD than what comes with the boards?

Hi Gary!

The Westin Sure-Grip Running Boards w/ Custom Installation Kit - 6" Wide - Black Aluminum # W73FX is a full kit made up of the Westin Sure-Grip Running Boards - 6" Wide - Black Aluminum # 27-6155 and Custom Installation Kit for Westin Molded, Sure-Grip, and Grate Step Running Boards # 27-2255, so it does include all the parts needed to get installed.

The mounting hardware included in the Westin # W73FX kit will fit your 2026 GMC Sierra 2500 as long as you have the Crew Cab. I went through our fit-guide as well as Westin's to double check that so I can 100% confirm the fitment there. If you have a different cab though, let me know.

As to the two 1-star reviews regarding missing parts, both of them were ordered after Googling running boards for their vehicle (Joseph was a Rivian and Robin looks to have been for a Traverse) and then not using our fit-guide to verify the fitment. Unfortunately, this is a pretty common occurrence with running boards as the actual board (which is the only part both of them ordered) is pretty much universal. The mounting hardware on the other hand, is not. We have been trying to find a way to force people to use our fit-guide so this kind of thing doesn't happen, but that solution has eluded us so far.

Is this your every day truck or a work truck?
