need some advice on swapping 6\" blocks for 6\" springs "Ted" is selling some rear 6" springs: from "For Sale" forum i'd really like to replace my rear 5.5" blocks, but i'm concerned as to whether my truck will still sit even, or will the rear be higher/lower? any way to know aside from just purchasing the springs and giving it a go? and would this be hard to fix? ***i just did a little more searching - is it just better overall to go with an echobit shackle flip? about the same lift w/more flexibility?
