Rhino-Rack RTPB3 Backbone Mounting System – Land Cruiser 250/GX 550 2024+

Rhino-Rack RTPB3 Backbone Mounting System – Land Cruiser 250/GX 550 2024+

by Rhino-Rack
$474.99

Developed for the new Toyota Land Cruiser 250 and Lexus GX 550, the RTPB3 Backbone provides the vehicle-specific structure required beneath a compatible Pioneer platform. Three bases per side create six supported roof connections while the 19.8 lb assembly maintains a tidy, low-profile fit.

This is a mounting component rather than a complete rack, so the correct Pioneer platform must be purchased or supplied separately. Use it for LC250/GX 550 builds where secure platform support and integrated styling are priorities.
