Ford F-350 Nerf Bars – Westin R5 M-Series Wheel-to-Wheel, Black (1999–2016). Built for Super Duty owners who want confident step-in and bed access, these 5-inch bars run wheel-to-wheel with a purposeful, low-profile profile.

Developed and engineered in the USA, the R5 M-Series provides a broad, skid-resistant footing at each door plus a third step for reaching cargo. High-grade, corrosion-resistant steel and rocker-panel mounting help shield rocker panels and keep the bars tight to the body. Westin’s exclusive Isolator Bracket supports the section past the cab to reduce flex and unwanted noise. Includes full hardware for a bolt-on install; no drilling required. A modular design packs efficiently to help keep shipping costs in check, and injection-molded step pads and bracket covers add durability.
