PSR's Nissan Patrol GQ-GU Front Bump Stop 50mm Extension Diff Side (bolts onto diff) is a heavy duty lower bump stop extension that bolts into the centre of the front lower coil mount. These bump stop extensions are CNC machined from a steel billet and feature a large flared surface to provide a solid, flat surface which is ideal when using hydro or Landcruiser style bump stops (See PSRUNI-004). Our lower bump stop extensions also offer a method of bump extension without the risk of contacting the inside of the coil that can happen when running extra extensions under the bump stop itself.
