Detailed Features & Benefits
Westin PRO TRAXX 4 Oval Nerf Step Bars are engineered to balance strength, safety, and clean styling. The 4-inch oval steel tubing delivers dependable structural integrity while helping shield your truck’s rocker panels from road debris, parking lot hazards, and off-road obstacles. The PRO TRAXX 4 model features 30-degree OE-style bends at each end, allowing the bars to follow factory body lines for a seamless, integrated appearance.
Each step bar includes a heavy-duty, injection-molded polymer step pad that provides a wider and more secure stepping area than traditional round nerf bars. The textured surface enhances traction in wet or muddy conditions, improving safety for drivers and passengers alike. Fully welded domed ends ensure there are no exposed bolt heads or end caps—helping prevent rust and extending the life of the bars.
Designed with a rocker-panel-mounted configuration, these nerf bars deliver both functional step assistance and added side protection. Vehicle-specific mounting kits ensure proper alignment and fitment, while some applications include injection-molded bracket covers for a cleaner, more finished look. Available in durable black powder coat or stainless steel finishes, the PRO TRAXX series lets you match your truck’s style while upgrading performance and protection.
