We strongly recommend that you anchor down the K9/B8 during transit in the Land Rover Defender; this can be achieved securely by using this Kit. Installation requires the fitting of the two “O” rings into the top of the Defenders wheel arches and then fitting into place using the ratchet strap, to do this only basic DIY skills are required and once fitted removal and reinstallation take only a few minutes. All components are non-rusting.
