The R5 M-Series Nerf Step Bars are built from premium steel that is engineered to withstand harsh conditions and resist corrosion over time. The textured black powder coat finish not only adds a rugged aesthetic but also provides excellent protection against scratches, chips, and environmental damage.

Injection-molded polymer step pads offer superior grip and durability, ensuring safe footing in wet or muddy conditions. The modular construction allows for easier shipping and installation, while the included bracket covers provide a polished, factory-quality look.
