To protect my steering linkages from damage during off-roading I installed a steering guard. A steering guard reduces the risk of damage to the Pitman arm, Drag link and steering damper, which are located at the front of the vehicle in harms way. Damaging these could see the vehicle stranded a long way from help.
I chose an APT Fabrications Defender Steering Guard as it is a quality Australian made and owned product and priced reasonably when compared to many of the British imports. All the necessary bolts are included in the kit. The guard can be purchased from http://www.aptfabrications.com.au
Installation was fairly easy taking me a couple hours with the fitting problems I had due to my non-standard recovery hooks.
