Yakima FlushBars are a solid, quiet, sleek, factory looking roof rack requiring only a Fit Kit to mount to your car. Each FlushBar is only a single bar.
The Rhino-Rack Backbone is a mounting system for your Land Rover Discovery 3 & 4. Connecting to your vehicle's roof via 4 bases on each side, it allows for a Rhino-Rack Pioneer System to be fitted on top.
