Westin PRO TRAXX 4 Inch Oval Black Nerf Step Bars

The Westin PRO TRAXX 4 Oval Nerf Step Bars are a premium running board solution engineered by Westin Automotive to deliver the ideal balance of everyday utility and clean, factory-integrated styling. Built for truck and SUV owners who demand dependable cab accessibility without compromising their vehicle's appearance, the PRO TRAXX 4 line is designed to perform reliably season after season.

At the core of every PRO TRAXX 4 is a 4-inch oval steel tube construction paired with heavy-duty injection-molded polymer step pads featuring embedded moisture-diverting channels. This combination creates a wider, more secure stepping surface that maintains sure footing in wet, muddy, or icy conditions year-round.

Key Features:

• 4-inch oval steel tube construction engineered for strength and long-term durability
• 30-degree OE-style bends that follow the vehicle's body lines for a clean, factory-matched profile
• Seamless domed ends — no exposed end caps or bolt heads, minimizing rust entry points and delivering a polished finish
• Rocker panel protection — the rocker-mount design helps shield rocker panels from road debris and impact damage
• Injection-molded polymer step pads with moisture-diverting channels for reliable grip in all weather conditions
• Bolt-on installation with mounting kit and hardware included — no drilling required on most applications
• Multiple finish options available across the product line to suit different style preferences and durability needs
• Warranty coverage varies by finish — polished stainless steel variants are backed by a Lifetime Warranty against manufacturer defects; black powder-coat variants carry a 3-Year Warranty
• Designed and engineered by Westin Automotive in San Dimas, California, USA
