adamm,
The MBRP will not fit the rear axle (take a look that diff is HUGE!!) and the frame/chassis on a 350 cab and chassis,450 or 550 is longer than a 250/350 pick up. We have an aluminized system that will bolt right on as it's designed for the 550 from the beginning. Give us a call and we'll get all your questions answered etc.
