as mentioned before the best way to do the front is spindals. the only drawback of doing just spindals in the fron ti that you need a much stiffer or adjustable shock up front or the same height springs up front with a higher spring rate. im not sure if you have noticed how soft the springs are on the front of your rig, but if you just lower it without the added spring rate it wont corner much better at all. a 2 inch belltec drop spindal with some adjustable shocks and a 2 inch spring are the way to go in my eyes. i installed them on a 97 a few months back along with a drop shackle and overload in the rear. the truck went down the road GREAT(a little stiffer, but thts what we wanted for the corners) a couple weeks later we beefed up the sway bars front and rear. added some 18 inch rims and some 40 series tires and you could corner that truck a lots smoother and faster yet still cary the weight rated for a c1500. i do agree that air bags are the way to go if you have the cash and can do the work yourself. but they are spendy.
