my kick has 31s, did a 2 inch sl and 3 inch bl, trimmed back of frt fenders and all is well, the only issue is with my sons old kick we were going top do the same but the body mount were so rusty we couldnt do the bl, with a 2 inch sl we ran 235s witch worked well, new mounts can be built fairly easy if you are a fabricater of sorts??
