Get a boost, with Westins R5 M-Series Wheel-To-Wheel Nerf Step Bars. The extra wide 5in. footprint step design provides easier and safer vehicle access for both drivers and passengers. Developed and engineered in the USA, the R5 M-Series Wheel-to-Wheel Nerf Step Bars feature three oversized skid resistant step pads allowing easy access to the vehicle cab or truck bed cargo area. Built with high-grade and corrosion resistant steel designed to mount directly to your vehicles existing rocker panels. The modular design saves you money on shipping, as no truck freight costs are required. Also included are injection molded bracket covers for a clean and stylish look. Westins exclusive Isolator Bracket supports the step bar past the truck cab, a feature that competitors do not offer. Without an Isolator Bracket, the step area that extends past the vehicle is left unsupported. Westins unique design provides added bar support without resulting in annoying creaking sounds.
