on that same note you can stiffen the front. As a general rule, the stiffer you go with the springs/shocks, the more traction transferred to the other end. For example, stiffening the front suspension will give greater rear traction and stiffeneing the rear will give greater front traction and so on. Raising the ride height has the same effect as stiffining the springs: higer in the front=more rear traction, higher in the rear=more front traction and so on. Be careful, because it is easy to go too far with either ajustment. If you make a change and do not like it, undo what you did and make a smaller adjustment or try something else. for example if you raise the front ride hight and now the truck pushes the front end, dont stiffen the rear springs. Instead, undo that change and try a smaller adjustment or soften the front springs a little. You will probably have to make several adjustments to get the perfect balance, so be patient. different weights of shock oil have similar results as different spring weights, but dont go heavier than 40wt. shock oil if you intend to ever drive the truck off road. The thick oil will not allow the suspension to absorb the off road bumps.

Also notice, you say you are breaking in the stadium truck, but you are doing it on pavement (I think) If you ever intend to do off-road driving, you should tune off-road. Your perfect pavement settings probably will not work very well on dirt.
