Loaded the truck up to almost full overland weight today to conduct some tests on the ride height using the existing OME shocks. As per an earlier post the truck was already sitting level with the fixed load and I suspected that with the full weight in it the rear would be sagging. From the results table it can be seen that the rear distance to top of wheel arch from ground (through wheel centre line) is an average of -33.6mm below same for front wheel arch. It looks to be sagging in the rear by eye too. I'm not sure what the design height is (or more importantly what the relative difference front to rear is on an AHC system). I need to research this. However my thoughts are it needs to be higher at the back and therefore some new beefier springs will be needed. The AHC has gone from my truck and the front torsion bar (OME HD) adjusted to provide the right level of lift originally
