In my non 4wd experience Koni adjustables take a lot of beating......But when I was looking for our Patrol I found that all the ex Telstra Patrols had OME fitted. Or at least all those I looked at. These have a 2" lift, carried heavy loads regularly over remote rough roads & I would expect that Telstra would fit the brand of shocks that they got best service out of.
Cuppa. ♨
