Like was mentioned before, I would replace all the wear parts first (bushings, mounts, etc...) with polyurethane parts. Then I would put new shocks on it (Bilstein 5100s or something similar). There are several options for upgrade sway bars. I know Hellwig and Addco sell them for both front and rear. For control arms, Moog sells replacement uppers. R Series, I believe is what they're called. Also, I'd look at installing a steering stabilizer; Rancho and Rough Country both sell kits for our trucks. Traction bars are also an option, if you have axle wrap issues (I never did in my '98 Z71). I would also look at upgrading the factory steering box to a Redhead or AGR box. And look at upgrading your steering components. You can order custom tie rods to strengthen that weak spot, and Cognito sells pitman arm and idler arm braces, as well as an upgraded idler pivot assembly. Moog sells greasable pitman and idler arms as well. Also, don't forget about the most basic thing: shoes. Are your tires in decent shape? This can make a very big difference in ride and handling.
