Anyone know by adding stiffer front shocks, will that increase the front GAWR. Or am I stuck with what I got.

 

Your stuck. Shocks do not add to the strength of the suspension.

 

Shocks do not support the truck at all. They simply make it move slower which cushions the bumps. Your basically stuck. You could add beefier springs but the rest of the fronts suspension (mounting brackets, steering components, etc) aren't designed to safely support anymore weight than is listed in the drivers door sticker.
