This is the ARB BASE Rack vehicle-specific mount kit for the 5th-generation Toyota 4Runner — the legs, feet and hardware that anchor an ARB BASE platform to your factory roof line. It is the structural link between the rack and the truck, engineered to spread load and keep the platform low and rattle-free.
The kit uses ARB's alloy leg system in a textured black finish that matches the BASE platform, locating the rack at the correct height for the deflector and rail accessories. Order it with a BASE platform sized for your build — on its own this is a fitment component, not a complete rack, so it carries no cargo until the deck is fitted.
