Rhino-Rack RTRB1 Backbone Mounting System 3-Base Roof Rack Kit

The Rhino-Rack RTRB1 Backbone Mounting System is a vehicle-specific roof rack foundation designed to connect directly to your vehicle's existing solid factory roof rails. It provides a rigid, multi-point mounting base that enables a Rhino-Rack Pioneer Platform to be securely fitted to the roof — dramatically increasing load-carrying capability and expanding your rooftop accessory options.

The Backbone system attaches to your vehicle's factory roof mounting points and distributes the weight of your cargo more evenly through the body of the vehicle, improving structural integrity and payload capacity. With multiple mounting bases per side, the system provides enhanced load distribution for use with Pioneer Platforms, Vortex Bars, or Heavy Duty Bars.

Key Features:

• Multi-Point Mounting: Multiple bases per side for superior load distribution and increased roof capacity
• Pioneer System Compatible: Engineered as the foundation for Rhino-Rack Pioneer Platforms, Vortex Bars, and Heavy Duty Bars
• Stainless Steel Construction: Made from heavy-duty stainless steel with a black powder-coat finish for strength and corrosion resistance
• No Roof Drilling Required: Connects to the vehicle's existing factory anchor points — no bodywork drilling needed
• Aerodynamic Profile: Designed to minimize wind drag and reduce road noise at speed
• All Hardware Included: Complete kit with all mounting hardware, fasteners, and detailed installation instructions
• Tested to International Standards: Meets ISO PAS 11154-2006 and Australian Standards AS1235-2000 for road vehicle roof bar testing

Installation is straightforward and designed to be completed by one person in approximately 1.5 to 2 hours. The Backbone system is the ideal starting point for building out a full overland or adventure rooftop carry setup, supporting a wide range of Rhino-Rack accessories including awnings, bike carriers, kayak mounts, lighting brackets, and more.
