I had ARB install dual-rate Dakar leaf springs which gave me 80+mm in the back and about 43mm in the front (Dakar HD springs). Nitrocharger Sports shocks were used all around.
Now this was back in 2011. I still have the same springs, same shocks and the ONLY thing I've done is replace the little pads between the leaves and give them all a clean. They still work perfectly, and we tow a 2.5T caravan and travel on some very rough outback roads.
I just had Fulcrum 2" enhancement lift fitted 2 weeks ago. So far so good and its rides great. Supplied and installed was $1890. I've just completed a 3200km round trip from Brisbane to NQ and couldn't be happier.
