Denny, I changed out all my gas shocks for cheaper less duty shocks. I was having trouble with to short of a shock on front. Due to lowering of the front a little bit over time, I lost track of the shock length and over hard bumps they would hit the inter stops. I went with a standard duty car shock, I found the truck shocks I was using were just to stiff for the truck. It rides much better now. The rear shocks were heavy duty load masters, It now has a car shock as well. I could jump in the bead and not get it to move, now it almost bounces like a real car would.

I guess what I am saying is, you might not want the heavy duty even though its a truck. Mines sure likes the soft, cheap shocks much better. Mine only weighs 3200 lbs with me in it, not sure what yours weighs.
