I would not go more than 6 in., which will put your tire more to the outside, and you will need a stiff rear shock,so they dont rub the wheel wells, and depends on what size tire also, I have 10 in welds with 325-50's and 6 and a half BS, and I needed 1.5 spacers to clear, and also lakewood 50-50's
