I drove the dealerships mannequin a base Big Bend with a level kit no crash bars and 35” drove nice and no rubbing.
You might be able to squeeze 37” if you use the DV8 inner fenders but not sure, probably won’t have full articulation. And I talked with the guys that helped build the Bronc busters bronco and they said you can fit 40” if you are willing to cut your fenders, little extreme but may be possible.
