Ok, the truck is running great. Now I would like to decrease the amount the rear end compresses on takeoff and at full trhottle. I am running 40W AE sock il now. Which would be better, increase shock oil weight, go to heavier springs (4# or 6#), or both? I'm thinking I might get a little more bite and quicker takeoff if the compression doesn't have to compress so the front is pointing to the clouds before the truck goes. I don't want too much that it breaks loose and spins. Open for suggestions.
