AMP Research is the leading provider of power-retractable running boards, making waves with its original PowerStep™. While providing sufficient assistance for most individuals, AMP Research offers this beefier, lower-hanging iteration, the PowerStep™ XL! This heavy-duty PowerStep™ retains the same general design as AMP's conventional retractable running boards with a few improvements geared toward oversized and heavily lifted applications. The upgrades include a rugged housing that the boards retract into, providing a more robust appearance for lifted rigs, as well as boards that drop an additional 4 inches lower than other PowerStep™ models, making it easier to get in and out of your ride! Like all other PowerStep™ variants, the XL is manufactured entirely from durable die-cast aluminum, ensuring maximum strength and minimum weight. All aluminum components are anodized and coated with a military-grade PTFE (Teflon), preventing surface corrosion. | AMP Research PowerStep XL 77104-01A
