Have 2" blocks in the rear? My buddy is wanting to lift his blazer 4" to clear some 35 inch tires and I came across an 80's 2500 being parted out locally that has a lift and a few other parts that we can use. The front measurement is thrown off because the 6.2 liter diesel is gone, along with the tranny and T case. I guessed from comparing the blazer to the truck in measurements and some guesswork might have the lift at about 3-4", but the 2" rear blocks are making me wonder. I guess it could be less lift than the front to level the truck out, but I was wanting a 2nd opinion. Also, would the springs be safe to swap between the trucks? For example, would the weight ratings be different on the front springs? If he goes for it, he's going to run the blocks in the rear until I either he gets a shackle flip, or I have a weekend to devote to making a poor man's flip for him. Thanks in advance for any help. I may borrow the digital camera and get pics of the truck in question tomorrow.
