Yup Tom, exactly that...
I run Calmini coils with a 1 inch spacer for a lift of about 3.5 inches......on 35 inch Nitto Mud Grapplers
Yes...I had to do some surgery to the back of the front wheel wells for clearance...
...and some cladding trimming at the front.
I'd rather cut out, cut off wheel well bits that are NROV ( not required on voyage!)..
...than lift the body any higher.
