4\" suspension lift I want to do a 4" suspension lift on my '87 K5 using replacement front/rear springs and no blocks, I already have the quad shock front end, and also want to add a dual-shock stearing stabilizer. My question is....what do you guys recommend as a lift kit?? I was thinking of going with the complete setup from Super Lift, with the ez-ride springs (think that is what they are called) and then adding a helper spring for towing. How is this setup....will it work for moderate offroading and a fair amount of towing??? Any other ideas or systems that you like, let me know...I am new to this type of mod.
