The AMP Research Plug-N-Play System simplifies the installation of your PowerStep Running Boards. Designed to make installation a breeze, the innovative Plug-N-Play harness eliminates the need to gain access behind the door panels during installation. This not only saves time during installation but also eliminates the need to remove interior components. These extruded aluminum steps feature full-length internal ribs for rock-solid stiffness and a high-texture powder coat finish for maximum grip and durability. With a 600lb load capacity per side and maintenance-free, self-lubricating bushings, the PowerStep is built to last and gives you the ultimate in styling and function. Its handsome design, all-weather performance, and legendary reliability set the industry standard, and AMP Research backs the PowerStep with an industry-leading 5-year/60,000 mile warranty.
