hey does anyone know of some shocks that are stiffer than stock gm shocks for my 03 sierra, 2 wd, and ones that arent drop shocks, i have drop spindles but kept all my ride, so i need factory sized shocks, but i want some really stiff ones, and i want to do away with my limited slip cause it will dick u up in the rain when it kicks in while ur playin, so i want to run like some air lockers or something, any ideas on that?
