2004-2006 GMC Sierra 1500 Crew Cab FAQ
Do these products fit a 1999-2003 Sierra 1500 Crew Cab?
Do not assume so. The current live products and collection rules are for 2004-2006 Crew Cab applications. Choose only a product page that specifically includes your truck’s model year.
Are Crew Cab boards interchangeable with Extended Cab or Regular Cab boards?
Do not assume so. Cab dimensions can change board length, brackets, mounting points, and step position. Match the product to the exact Crew Cab application.
How should I compare 5-inch, 6-inch, and step-board designs?
Match fitment first, then compare stepping surface, profile, width, dimensions, material and finish details, and package contents. Width or finish alone does not determine compatibility.
What should I verify before installation?
Check the exact model year and Crew Cab application, included brackets or hardware, package contents, and installation notes. Do not assume drilling requirements or factory mounting-point use unless the product page states it.
