Dobinson springs are made in Rockhampton. I currently run a 2" lift on my GU. I have found the Dobinsons have improved the ride and handling on road as well as off road. You need to consider the way you use your vehicle as well as the accessories fitted and the load carried before making your decision on the springs. For example, there are 5 different springs to suit the front of a GU Patrol in the 2" range. I found the guys at Dobinsons to be very helpful and would recommend them to anyone.
