AeroTread running boards install using a track mounting system to attach vehicle-specific brackets, and pre-existing holes in the vehicle’s frame are used to eliminate drilling, speed up installation and ensure stable footing (NOTE: Mounting brackets are sold separately, see the application information to determine which brackets and boards fit your vehicle).
