A lot of company's make a "comfort ride" lift kit and there 2"-8" lifts if your going to be driving in the snow then a 2"-4" lift would help and new "comfort ride" springs will ride better top that off with some external reservoir shocks and your golden, and it would not hurt to see if you need new body bushings and also check your suspension parts and make sure they don't need to be replaced, all the stuff that needs grease. My truck road like i was going over a washboard on smooth dirt roads and i put all new parts under my truck and bushings and mounts, after that it road like a dream (for a truck) and remember its a 1982 Chevy we don't buy these trucks for there ride, they don't have coils and will never ride like a 2010 Chevy truck and welcome to the site i hope i could help.
