This is a direct bolt on kit for the Volkswagon Golf mk5. No other company supplies them in the UK. The kit comes with two 12 mm thick steel hinges which are CAD designed and CNC cut to pinpoint accuracy. The shocks will cope with 600-1200lbs in pressure and with this strength we offer a lifetime warranty on the kit. No welding is required with these kits. The package includes all the necessary instructions you need to carry out the fitment.
