Description

Westin Pro Traxx 4 oval tube nerf step bars feature a heavy-duty step pad that provides a wider, more secure step area. They also feature deep paved waterways to keep the step area dry and full textured step areas are great for scraping mud off of your shoes, which means a cleaner interior. Made with fully coated, seamless domed ends with 30 degree OE-style bends, these nerf step bars are available in various lengths and diameters, in your choice of polished stainless steel or black powdercoated steel. Mounting kit is included for an easy bolt-on installation, no drilling required. For durability, functionality, and great looks, Westin Pro Traxx 4 oval tube nerf step bars can't be beat. Order the model designed for your specific truck application.
