Hey i got a 4x4 2000 blazer and i want to lift it a little, 2inch body then 1 1/2 shakels and tbar crank. I want to know what size tire i can fit if i do that and have 15x8 rims with 4inch back spacing. I want to be able to do a little mudding on the weekends with it so im trying to up size the tires

 

This has been covered many times on the forum . DO a search I bet youll find all your answers

 

Body lift, no problem. T body GM vehicles don't take to kindly to messing with chassis ride height, (torsion bar crank). If chassis ride height is not within factory specs, you will experience premature failure of all 4 ball joints, all 4 CV joints, both outer tie rod ends, and both front shocks. Not to mention tires and torsion bars. If money isn't a problem, make sure you have the time, tools and knowledge to replace that stuff.... often.... and on a regular basis
