not a clue on the clearances. i am using my rear 5.29 third in it. i have to add more studs and do something with the e-locker notch. i need it for the width otherwise i would have to have 3" wheel spacers on an ifs housing to match the front. i wasn't extremely worried about shaving it i just have to ditch the fill plug. it hangs down really far. i was going to bring the portaband home from work and just slice it off
