after reading through pages and pages of this forum and the suburban forum, i think i finally decided on a lift for my 1990 3/4 suburban. at first i wanted a 6" lift, but after reading, i decided that i should start off with a 4" lift. it seemed that a lot of suburban owners have a 4" lift with 35s, a couple with 36s. this truck is my daily, and might see some soft soft trails once in a great while. so i figured that a 6" lift would be pointless. what i hvae picked out, all from ORD is the 4" shackle flip for the rear, and the 4" EZride kit for the front. it says all kits include spring bushings and u bolts- so that should mean the front is all set right? below that, it says the steering arm is recommended, which i will also get. for the rear, would you guys suggest to get new bushings to install at this time while its apart? also, since i will be using the stock springs, should i buy new u bolts for the rear? as i was browsing their website, i came across the swaybar correction/disconnect, and wondering if i should also do this at the same time? the price is right, but since it wont see much offroad abuse, didnt know if it would be pointless? and one more question for now- when i was looking at 6" lifts, most places said that the crossover exhaust pipe would have to be modified. is this the same for this 4" lift? should i buy some headers and get dual exhaust so i dont have to worry about that? i hope i sounded half intelligent in this post. after reading a lot of posts, you guys really help other people out, so i hope youll do the same for me.
