The Steelcraft STX400 Step Boards are designed for customers who want a rugged step upgrade with modern styling, dependable footing, and a refined truck-ready appearance. The 5 inch step pad design gives compatible trucks and SUVs a practical place to enter and exit while adding a clean aerodynamic side profile. With aircraft-quality extruded aluminum construction, aggressive step pads, and durable finish protection, these step boards deliver daily access with a strong finished look.
The STX400 design is a strong choice for customers who want a step board that feels tougher than a smooth factory-style running board but more refined than a heavy drop-step system. The board shape creates a clean lower-body accent, while the aggressive step pad layout gives drivers and passengers a defined stepping area. This makes the STX400 a good fit for daily drivers, family vehicles, work trucks, towing setups, and customers who want useful access with upgraded exterior style.
Steelcraft builds the STX400 Step Boards with an extruded aluminum body for lightweight strength and corrosion resistance. This aircraft-quality construction helps reduce unnecessary weight while supporting dependable step function in everyday use. The aluminum body is paired with durable finish protection to help the boards stand up to rain, snow, road grime, dirt, and regular outdoor exposure.
The aggressive 5 inch polyethylene step pads are one of the key advantages of the STX400 design. These custom step pads are built for traction and long-term use, helping support confident footing in wet, dusty, muddy, or snowy conditions. The raised pad layout gives drivers and passengers a secure place to step while helping the boards maintain a clean, finished appearance from the side.
Depending on the selected configuration, STX400 Step Boards are available in Black/Black or Black/Stainless styling. Black/Stainless configurations add stainless steel cover plates for a more polished appearance, while Black/Black configurations support a cleaner dark exterior theme. Both styles pair well with wheels, grille guards, bumpers, mud flaps, bed covers, racks, lighting, and other truck and SUV accessories.
Steelcraft designs these step boards around vehicle-specific applications, helping the boards mount cleanly on compatible vehicles. Custom mounting brackets are included when applicable, and supported applications are designed for a straightforward 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, work use, polished styling, or a clean rugged side profile, the Steelcraft STX400 Step Boards deliver lightweight aluminum step function with aggressive pad traction and durable exterior protection.
