I have a 2004 Silverado with a Bell Tech 2/2 drop. I am running the Nitro-Drop shock but still find the suspension bounces a lot. My tires are rubbing the wheel wells over highway overcrossings or if I take a turn at speed with any inconsistancy in the road. Can someone recommend another shock? Something more performance based that won't sacrifice too much ride comfort?  

Been running the Belltech nitro actives on a 2/4 drop with no rub or bounce problems at all. Not to bad of a ride on them either, give em a shot, i recommend em.  

another good shock to use is Edelbrock IAS for lowered trucks, not the regular ride hieght IAS shocks. i have run regular IAS shocks and they take alot of the bounce out, and i mean "alot". it stiffens the suspension in all active motions. have to look hard for the lowered truck IAS, i have only seen them on a couple of sites.  

What size rims & tires are you running? Does it only hit in the front and where?
