you shouldnt have to tub it with 17s.

no.

Depending on how you are lay'n out.. If you just bag it no you will nt have to tub.. If you do a traditional body drop "NO" you won't have to but if you do a stock floor you will have to cut alittle or just heat it up and roll the top in . Not much but a little......
