1999-2006 Chevy Silverado 1500 Extended Cab FAQ
Will every product on this page fit every 1999-2006 Silverado 1500 Extended Cab?
No. Exact mounting application and product design still need to match the truck. Use the individual product page as the controlling fitment source before ordering.
Are Extended Cab boards interchangeable with Crew Cab or Regular Cab boards?
Do not assume so. Cab dimensions can change board length, brackets, mounting points, and step position. Choose a product that specifically names the Extended Cab configuration.
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 Extended 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.
