The Steelcraft STX300 Running Boards are designed for customers who want clean step access with polished styling, dependable footing, and a premium OEM-inspired appearance. The 4-1/2 inch stepping surface gives compatible trucks and SUVs a practical place to enter and exit while keeping the lower side profile refined and easy to match with factory body lines. With aircraft-grade aluminum construction, textured step platforms, and stainless steel accent detail, these running boards deliver everyday function with a more upscale look.
The STX300 design is a strong choice for customers who want running boards that look integrated with the vehicle instead of oversized or overly aggressive. The polished board face, rounded bullnose trim, and decorative center panel help create a clean side profile that works well with chrome, stainless, polished, and bright exterior accents. This makes the STX300 a good fit for daily drivers, family vehicles, tow vehicles, work trucks, and customers who prefer a more refined step upgrade.
Steelcraft builds the STX300 Running Boards with CAD-designed aircraft-grade aluminum extrusion to help provide strength without unnecessary weight. Aluminum construction helps resist corrosion from rain, snow, road grime, and daily outdoor exposure. This gives customers a running board system that feels solid underfoot while helping reduce rust concerns compared with heavier steel step systems.
The injection-molded textured step platforms are one of the key advantages of the STX300 design. The textured stepping surface helps support secure footing during daily entry and exit, especially in rain, snow, dust, mud, or road grime. For taller vehicles or family-use trucks and SUVs, the added step area helps make cab access easier and more comfortable for drivers and passengers.
The decorative 304 stainless steel center panel adds a premium visual detail while helping create a clean dividing line along the running board face. A 2 inch tall black elastomer back splash helps reduce mud, water, and road debris from splashing onto the step platform. These details give the STX300 a more complete appearance while supporting practical everyday use.
Steelcraft designs these running boards around vehicle-specific applications, helping the boards mount cleanly on compatible vehicles. Custom mounting brackets and hardware are included when applicable, and supported applications are designed for a straightforward bolt-on installation using vehicle-specific mounting points. Customers should confirm vehicle year, make, model, cab configuration, trim level, and rocker-panel equipment before ordering.
Whether customers are upgrading for easier cab access, daily driving, family use, towing support, polished styling, or a clean premium side profile, the Steelcraft STX300 Running Boards deliver aircraft-grade aluminum step function with textured footing, stainless steel detail, and refined exterior style.
