go either OME or bilstein 5100s and eibach springs on the front and as far as the back goes, i aals will really stiffen up ur ride. im not sure about the blocks. never dealt with them. but although it may be a little pricey, new OME springs for the rear isnt a bad way to go. eventually i wanna score me the toytec
ultimate coilover kit. and some new rear springs. just running basic skyjacker 3" with aals right now. as far as the tires, if you dont want any rubbing, stick with what youve got. but if you wanna upgrade to a 285/75R16, you may want to look into what you need to trim first. you may be able to get out of the cab mount chop with spacers or rims with a smaller backspacing. still may have to do a little on the fenders though. imo its not worth it for the extra half inch of lift you get from them.
