About four years ago, I put a 4" Superlift suspension on my Blazer. Lift included new springs front and rear, shocks front and rear, and pitman arm. After I was done installing the lift, the rear sat about two inches lower than the front. At the time not knowing better, I put two inch blocks in the rear. Well now I in the middle of replacing everything, meaning the floor from the firewall to the tailgate, rockers, body mount supports, tailgate mount beam (whatever that thing is called) and a new motor. Well I was thinking about installing the Offroad Design Shackle Flip to replace the blocks, but I am worried that the rear will sit two inches higher. On top of that, I plan on starting to take the top off this summer, making the rear sit up that much higher. Should this be a concern and if it is, without replacing the springs what could be some of my options? Second question: Since the lift, the damn thing rides like a tank. Meaning a stiff as hell ride. Now the shocks do need to be replaced. They are some Explorer Pro-Comps, don't remember which model or part number. There is four up front and two for the rear. What have you guys had luck with for as shocks for a 4" lift? Note: A while back I ordered some shocks from Rancho for a 4" lift and they was to short. They were fully extended when the truck was on level ground. I called them about it and they said that those were the right shocks. I think that they will work great for stock Blazer. If someone is interested in them for about $150 for 6 shocks let me know. I paid close to $250 and only installed one and took it back off. Any opinions or ideas on these would be great. Thank you in advance.
