ARIES ActionTrac powered running boards are unique from other power side steps because they are actually two steps in one. This patented step-within-a-step design -- combined with a no-drill bracket installation on most models, control module operation and powder-coated aluminum construction -- truly makes these retractable running boards an asset for the offroad truck or Jeep, particularly as lifted truck steps. ActionTrac powered running boards have one 4" wide step on top of the main housing and one 3" wide that automatically deploys as needed. When the door opens, the control module deploys the power step 8" below the main step, 15" below the doorsill, depending on the model. This two-step design offers enhanced safety and easier vehicle entry and exit, especially on large, lifted vehicles. It's also very helpful for families with young children and for elderly passengers. The boards contour to the vehicle and offer extra protection for the rocker panels from small road debris. For additional safety, the module is able to detect any obstructions during operation to avoid pinch hazards. LED lights are also built into the housing to illuminate the steps when deployed. ARIES ActionTrac powered running boards are made for vehicle-specific installation for a custom fit. They use pre-existing factory holes for the brackets to eliminate drilling on most models. They also do not require any splicing into factory wiring. These particular running boards fit specific years of the Ram and Dodge Ram 1500, 2500 or 3500 (see application info to verify fitment). Each set is constructed from powder-coated aluminum to be strong, lightweight and non-corrosive. The quiet, maintenance-free rotary motor is shielded within the main housing, along with the power step pivot points and all electrical components, protecting them from the harsh elements. NOTE: Boards, brackets and wiring are included.
