YHTAUTO Black Powder Coated 4-Inch Running Boards for Chevy Silverado & GMC Sierra 1500/2500/3500 (1999-2019) Extended C

Confident Fitment Designed specifically for Chevrolet and GMC models, including Silverado/Sierra 1500 (99-18), 2500 (99-04), 2500 HD (01-19), 3500 (01-06), 3500 HD (07-18), and Silverado 1500 LD/Sierra 1500 Limited (19) with Extended Cab (2 full-size doors with half doors), excluding C/K Classic.

High-Strength Steel Construction Crafted from high-strength Q235A steel, these step bars are enhanced with an electrophoretic layer and powder coating. This dual-layer protection not only improves wear and corrosion resistance but also adds a sophisticated look.

Thick & Sleek Design Oval-shaped truck side steps are designed using computer numerical control, ensuring thick bodies with fully welded 90° ends. This design allows for easy passage through mud while providing reliable protection. The aerodynamic flair adds a modern touch to your vehicle.

Step Comfort The 4-inch injection-molded polymer step pads have undergone rigorous testing: 10,000 dynamic load trials, 24 hours of static load inspection, and 720 hours under Xenon lamp aging monitoring. These tests demonstrate minimal pedal surface drop and preserve ground clearance, ensuring safe and comfortable entry and exit.

Frame Mount Packaging Running boards come with all necessary brackets, bolts, and nuts for installation. If your vehicle has preexisting mounting holes, no extra drilling is required. The packaging features five layers of reinforcement to prevent deformation during transportation and installation.
