Nerf Steps | 3-Inch Tube | Crew Cab | Ford F-250/F-350 Super Duty (99-16)

Rough Country’s 3‑inch tube nerf steps deliver continuous wheel‑to‑wheel coverage specifically engineered for Ford F‑250 and F‑350 Super Duty Crew Cab trucks released from 1999 through 2016. Designed to mount directly over factory rocker panels, the tight‑fitting profile protects vulnerable sheet metal from trail debris and conveniently hides underlying frame rails beneath a clean, uninterrupted line.

Each step forms around heavy‑duty steel with a verified.084‑inch wall thickness, then receives a double‑layer protective treatment consisting of a zinc base coat topped with a black powder finish. This construction standard actively shields against road salt, mud, and UV degradation. The bracket geometry maintains clearances for both stock suspensions and vehicles fitted with aftermarket body lifts, eliminating fitment guesswork.

Installation and Long‑Term Support

Moving the vehicle into position and securing the brackets requires only standard hand tools and the supplied hardware. The direct bolt‑on architecture typically finishes in approximately 1 to 2 hours. Once mounted, the steps provide reliable step‑up clearance for cabin access while maintaining a low visual footprint.
