Nissan Patrol GQ-GU Rear Bolt in Drop Out ConeFEATURES Suits GQ and GU Nissan Patrol GQ GU Rear Bolt in Drop Out Cone are now available from PSR, our drop out cones are made from machine grade plastic rather than fabricated steel that is used by competitors. The main advantage with using plastic, is if a coil spring is contacted by a steel drop out cone it greatly increases the chance of causing a spring to break. Contact with a coil should be avoided at all costs.
