it could be street legal, lift laws are differant all through the states, same with canada, and in cali im sure you can have some pretty big trucks, i know in ontario here people drive around on 54's, but its a smaller city too.
it might be legal.. my cousin has a ford superduty lifted up about 3/4 that high and his is still street legal. you just have to get your headlights lower down or something i think. none the less, its a tippy mother f*er
