Let me start by saying that I've been burning up the SEARCH feature here for the last 3 days. What I've got: 4" TCI lift springs w/ early 4" stock shackles, dual gas shocks of unknown brand, push/pull steering w/ raised steering arm to a Corp. 10 bolt in the front, stock 4 leaf + overload springs in the rear w/ 4" blocks. What I want: #1 a better ride while maintaining the 4" lift, #2 good flex capabilities. What I'm gathering from other's experiences as a solution: using 52" springs w/ appropriate length shackle ~ 7" or so to prevent frame contact and provide good shackle angle up front, the way I see it, there's no need to move the front mounts forward, and this would be the same as a 48" spring and moving the rear shackle mount forward. Essentially, I want to move my existing rear springs up front w/o the overload leaf, however, some say cornering is terrible w/ the added flex - why can't I retain the stock sway bar w/ a disconnect kit from ORD to prevent the rollover? Some also say Xover steering is a must, well that's out w/ a corp 10 bolt. Will that only be an issue under Xtreme flex conditions? Can I limit droop with shock length or will they get destroyed? I also have a set of 3 leaf 52's out of a 1/2 ton P/U, would they be able to support the rear of my K5 and provide a softer ride and more flex? A lot said in one mouth full, but everytime I think I have a plan, I read another post and get spun around again, Please help . Jim.
