These look a lot like the "Clamber" running boards on Amazon... CLAMBER Running Boards for Ford Bronco 2021 2022 2 Door(Not for Bronco Sport), Heavy Duty Sand Textured Black Nerf Bars 7.5 Inch Width Side Steps Rock Sliders
The Clamber C2 ones have specific dimensions... 53.2 x 7.5 and the brackets look a bit different. Can anyone that has the 4WheelParts kind validate the length/width?
