If you do a suspension lift make sure you replace all your springs and shocks other wise your ride will be ****. It will also be a bit harder ride so you will need to slow down for the speed bumps.. :lol:
There is actually about a dozen different suspension brands on the market at the moment....but be warned a lot are having problems with the D40 for various reason.
Make sure you get the right set up for your truck. I got 300kg load rated springs in the rear to carry all my work stuff so when its fully loaded (800kg) I'm still about 40mm above standard. The big problem with that is when it is unloaded it sits about 70mm above standard and the a$$ end bounces around. You can usually get 3 sizes 300 kg , 150kg and standard. Note if you get heavy duty you will need longer brake hoses ($88).
The same with the front (3 choices). i have an all alloy V6 with no bull bar, so it is about 50mm in the front. Yours might not be so high maybe 40mm with the heavier diesel.
The up side of upgrading the suspension is better ground clearance, you can load it up without hitting the bump stops, less body roll and most importantly it looks tuffer.. :wink:
Arb have theres out at the moment to, but i wasn't very impressed. not much lift and there rear springs looked pretty ordinary. I did use there front shocks, because EFS still didn't have any at the time, but they should by now. The whole lot ended up costing about $1500.
