Wranger JL Vortex Cross Bars + Backbone Rack System Overview

The wait is over for Jeep JL owners. Rhino-Rack's Wrangler JL Backbone Mounting System is now available. The Backbone provides internal skeletal support frames for the included mounting plates. Interior integration of the Backbone support frames creates a series of 3 incredibly robust base mounting points on each side of JL hardtop roof.

Heavy duty RLT600 metal legs with Rhino-Rack's brilliant Quick Mount/Trigger Release technology are then attached to the base mounting points. Lastly, a set of 3 black Vortex Cross Bars are mounted to the legs. After the initial fitment, the RLT600 legs allow the cross bars to quickly be removed or re-installed by one person using no tools. With the Backbone + 3 Vortex Cross Bars system you can carry 265 lbs on the roof of your Jeep JL.

    Rhino-Rack Wrangler JL Vortex Cross Bars + Backbone Rack System Kit Features

    • The Rhino-Rack Backbone Mounting System allows you to tap into the interior support frame of the Wrangler JL hardtop, so you can maximize your carrying capacity and safely carry heavier loads- rated up to 219 lbs on road and 174 lbs off-road for 4 door JL Hardtops.
    • The strength of the backbone system is complemented by the simplicity of 3 heavy duty vortex cross bars, which maintain the strength of the backbone but add minimal weight themselves, leaving more carrying capacity for your gear.
    • A lockable cover plate protects the locking mechanism and is Masterkey compatible.
    • Aerodynamically designed with vortex generating rubber stripping on crossbars to minimize wind drag and noise on the road.
