Hey Tony, I never got a notification on your replies - thanks for the offer. I just said to hell with 'recommendations' and put the perch height where it needed to be so the truck was sitting how i wanted it to. They ride much better than the drop shocks (they were due to be replaced after 7 years!). Truck is running great - tempted to get the new rear links you offer but I don't know what the benefits would be vs the ones i have.
