Take your Jeep Wrangler JL Unlimited's roof rack capability to the next level with the Rhino-Rack Backbone Mounting System (RJLB1). Engineered specifically for the 2018+ Jeep Wrangler JL 4-Door, the Backbone system reinforces the vehicle's hardtop by connecting directly to the interior structure, creating a strong and secure mounting foundation for Rhino-Rack Pioneer Platforms and roof rack systems.

Designed for serious overlanders and adventure seekers, the Backbone system distributes roof loads more effectively, allowing you to safely carry rooftop tents, awnings, recovery gear, and other expedition equipment with confidence. Its concealed interior support structure maintains a clean factory appearance while dramatically increasing roof rack carrying capacity.
