Description
Style and Function. Now you can give your 3500 Sierra Crew Cab a rugged appearance, while also providing a convenient step for easy entry in and out of your truck, with a set of R5 M-Series XD Wheel-to-Wheel Nerf Side Step Bars. The big difference between the R5 M-Series XD and the original R5 M-Series is that the XD extends 3-inches lower than the originals making them ideal for lifted vehicles. As an added bonus these Side Steps also double as side armor to help provide additional protection from road and trail hazards.
Steel Construction. These R5 M-Series XD Wheel-to-Wheel Nerf Side Step Bars are manufactured from heavy duty steel for superior strength and rigidity. The Side Steps are then completed in a textured black powder coated finish for good looks and long lasting corrosion resistance. As part of the final assembly a set of rugged non-slip step pads are installed.
Bolt-on Installation. These R5 M-Series XD Nerf Side Step Bars are engineered to be a direct bolt-on upgrade using basic hand tools, so there is no drilling or cutting required for a clean straight forward install. All of the necessary hardware is included for installation, making this an easy job for anyone to complete in under two hours.
Three Year Warranty. The manufacturer covers their steel R5 M-Series XD Nerf Step Bars with a worry-free 3-year warranty against defects in materials or workmanship from the date of purchase. Some limitations may apply.
Application. These R5 M-Series XD Wheel-to-Wheel Nerf Side Step Bars; Black are designed to fit 2020-2025 GMC Sierra 3500 HD Crew Cab models with Long Box. Driver and passenger side included.
