looks like your k5 clears 35's fairly good with only a 2.5" if I went 3" I would have the option of 33's clearing in whatever cond and 35's clearing on the street pretty good...
ok here is what I plan to go with so far tuff country 3" all springs, mickey thompson classic ii 15X10...here is the part thats gonna make it I think..toyo 33x13.50 tires
on a 10" wheel it should look nice and they're true 33" tires so def should be a big diff with them and a 3" lift.
