Offroad Design 4\" shackle flip rear. - ?Front? I have a stock 79' blazer and plan to run 35" BFG M/T's. If I was to buy the Offroad Design 4" shackle flip kit - what are my options to level out the front? I want good axle flex and was thinking of Skyjacker 2" springs (I've heard they lift about 4"). Thanks.
