The Rhino-Rack Backbone 2-base mounting system is built for selected Gen 5 RAM Crew Cabs and 2019+ Gen 4 Chevrolet Silverado and GMC Sierra Crew Cab models, attaching via two bases per side. It provides a low-profile, vehicle-specific mounting point to accept Rhino-Rack Pioneer platforms and accessories, enabling robust roof cargo and tray installations while preserving a tidy appearance and solid structural support.
