The ARB roof rack fitting kit is a vehicle-specific mount system developed for Jeep Wrangler JL Unlimited with factory hardtop. It uses the roll cage and tub to distribute load and achieves a 287 lb carrying capacity when installed with the internal frame kit. The mounting kit includes M6, M8 and M10 fasteners, rubber gaskets for drill holes in the hardtop, and is intended for use with ARB roof racks to create a durable, load-rated installation.
