Smittybilt Nerf Steps are truly the next generation in side step technology. It features a 3-inch main tube with an innovative four-step drop down design with a cleated step plate. Each bar is custom-made for each application and provides one of the sturdiest attachments in the industry. The new stainless steel bars are constructed completely of 304 Marine Grade Stainless and comes with a limited lifetime warranty. The drop steps are welded on and then ground down and smoothed out to provide a truly finished look.
