The Rhino-Rack 2-base backbone mounting system for 2019–2021 Toyota RAV4 (XA50) connects to the vehicle’s solid rails using two mounting bases per side and provides the platform to fit a Rhino-Rack Pioneer system on top. As a purpose-built backbone kit, it creates dedicated attachment points for a Pioneer-style rack and helps integrate Rhino-Rack accessories with the vehicle roof.
