The GMC Sierra sits high to the ground. Access to your truck's cabin can prove difficult for some people, especially kids and elderly people, or those with back or knee issues. Adding a set of running boards, step bars or nerf bars will help make it easier for all to enter or exit your truck. You'll make it easier, safer and more comfortable to drive around in your truck. Free shipping on all orders from PartCatalog. Available for the Sierra 1500, Sierra 2500, Sierra 2500 HD, Sierra 3500 and Sierra 3500 HD.
