Hard to tell initially. Would recommend checking leveling kits first if all you’re looking to do is squeeze a little bigger tire in there. Jeep level kits run from as cheap as $30 to $4-500, depending on size. Full lifts won’t be cheap due to the ifs.
You’re going to have literally hundreds of options once the market catches up.
Ranger lift - this is a pretty decent kit for the ranger for $1200. The Bronco will be similar sized, but has coil overs front and rear, where the ranger is a leaf sprung rear. I would estimate $1800-2000 for a Bronco kit similar to this.
Body lifts are used on JK jeeps going to 37" tires.
The tires are getting so big in that size, that the inner top of the tread wants to hit the sides of the body tub at full flex.
Completely removing the fenders doesn't help with that.
I'm thinking of going with a very simple and subtle 1" body lift on my Basesquatch.
That will let me get rid of the SQ's extendedbump stops, and make room for true 35" tires.
The GY Territorys ( and all 315/70R17 tires) are actually 34.5".
It might not cost anything but a little of your labor. On the Gen-1 Raptors the Fox shocks were height adjustable. It didn't take long for someone to discover that little hidden gem. They came from the factory set at the lowest height. They have two additions positions to raise the height. Quite possible that the Bronco suspension may have the same. Until the Bronco is in customer's hands we won't know.
