okay, i measured the springs and they are 52"
so they will work on my blazer. and now more "stupid" questions. as far as lift kits go, is there a difference between the 1/2 ton and 3/4 ton? as far as spring rates and such. if i order the kit with blocks for the rear will it affect the ride, having new springs in the front and old springs in the rear? are blocks really a good way to lift it? i really want springs all the way around, but the price for rear blocks is attractive. so any advice would be welcome. thanks
