3. Features

• High-Tensile S/S 304 Construction: The step bars are manufactured from high-grade 304 stainless steel, meeting ASTM standards. The surface undergoes meticulous polishing using a high-speed rotating wheel and abrasive, enhancing its wear and corrosion resistance.
• Streamlined Design: Round truck side steps feature computer numerical control (CNC) with 90-degree bent ends, which aids in mud passage and provides protection. The design integrates with your truck's contours for an aerodynamic appearance.
• Durable Step Pads: The 3-inch injection-molded polymer step pads have undergone extensive testing, including 10,000 dynamic load trials, 24 hours of static load inspection, and 720 hours under Xenon lamp aging monitoring. These tests confirm minimal pedal surface drop and preservation of ground clearance.
• Robust Mounting: The running boards are designed for frame mounting and include all necessary brackets, bolts, and nuts for installation. No additional drilling is required if your vehicle has pre-existing mounting holes.
