Yes. Products are included only when their current listing identifies a 6-inch running-board or nerf-bar style. Check each product page for exact dimensions and construction.
Are these genuine GMC OEM parts?
Unless an individual product page explicitly states otherwise, these are aftermarket parts selected for the listed applications.
Is installation identical across the collection?
No. Brackets, hardware, and instructions can vary by kit. Use the instructions supplied with the exact product you order.
