We installed crossbars onto a 2021 Ram 1500. The crossbar system we used were manufactured by Yakima and is known as the Baseline system. The crossbars are attached to the vehicle by Baseline Towers using Baseclip 135 which mounts onto the weather stripping as well as clamping down into the door frame. The crossbars used in this setup are called Jetstreams, they feature a channel that runs along the bar to allow track mounted accesories. The weight capacity for this system is 165lbs.
