Description
Style and Function. A pair of RedRock 4-Inch Oval Straight Side Step Bars will make the strenuous task of getting in and out of your 2020-2025 GMC Sierra 3500 HD Crew Cab much easier. These Side Steps will provide you with a convenient step for easy entry, while giving your truck a rugged off-road appearance. In addition, these Side Steps also double as side armor to provide additional protection from both road and trail hazards, as well as dreaded parking lot door dings.
Heavy-Duty Construction. RedRock manufactures their Side Steps to precise specifications from heavy-duty, 4-inch oval mild steel tubing for superior strength and rigidity. These Side Steps are then completed in a 2-stage finish using epoxy pre-coating and high-grade, gloss black powder coating for aggressive good looks and long-lasting corrosion resistance. As part of the final assembly a set of rugged non-slip step pads are installed.
Direct Bolt-On Installation. RedRock engineered their Side Step Bars to be a direct bolt-on upgrade reusing the factory mounting points and included hardware. There is no cutting or modifications required for a clean straight forward install. Installation can be completed in about 2 hours with just basic hand tools and the help of a good friend.
