N-FAB RKR Rails Provide superior protection while enhancing the look of the vehicle. Constructed using 0.12 in. wall, 1.75 in. tubular steel, RKR Rails are treated inside and out for extra corrosion resistance so you know they are built to last. Finished with a durable textured black powder coat, N-FAB RKR Rails look as good as they perform both on and off-road. Making a great product even better, N-FAB offers optional Detachable Steps that are compatible with all N-FAB RKR Rails and Factory Toyota FJ Rock Rails. These steps offer convenient vehicle access for daily use and can be removed to allow for maximum group clearance when off-road.
