The Grenadier comes with the option of a full length Rhino-Rack. Weight 60kg. Payload 90kg. 1990mm wide x 2530mm long, and vehicle height with rack 2150mm + 100mm (whatever that means). The Rhino-Rack uses standard gutter mounting. Rhino also have a comprehensive range of attachements (using T-slot mounting) for their roof racks, many available from your Ineos dealer.
Front Runner have their Slimline II Roof Rack in a full length and 3/4 length offering. Full length rack details: Weight approximately 43kg. Payload not specified, but the dynamic roof loading allows an additional 107kg. 2570mm long. The roof rack kit comes equipped with eight Gutter Mount legs. Front Runner also have a comprehensive range of attachements (using T-slot mounting) for their roof racks.
Black Sheep have a quite different option. Their low profile roof rack sits directly on the roof and attaches to the roof grab rails rather than the gutter. Standard gutter mounting gives a maximum of 420kg static and 150kg dynamic. This sytem is quoted at a 250kg static load, and 150kg dynamic load for each segment – with the load distributed onto the roof. It comes as 2 base elements or add a third for a total area of 1600mm wide x1890mm long. I understand the weight is 2x12kg + 1x11kg = 35kg total.
A nice element with this rack is the solid base with multiple L-track mounts – in keeping with the mounting system used in the rest of the vehicle. Additionally, even in the maximum size configuration the Safari windows can still be used!
Rolling Space have a novel offering, with a customisable full length gutter mounted roof rack. Their low profile design alows the Safari windows to be used, but still with the advantage of a full length rack and potential light bar mounting. Their mounting system is also different from most, with neither l-track nor T-slot. Load limits pending, but will likely be simmilar to the Front Runner racks.
