i dont agree with the 3 in blocks. if you drop the front 2 in, to use the 3in blocks will put you a little higher in the front. barely, but still. 2in blocks looks closer to level and you dont have the axle hitting the frame on harsh terrain. use helper bags or air shocks to keep the bed as usefull as it was stock. also, with any change of rear height, its good to change the shocks out. stiffer is better when you go low.
