heavy duty shocks and springs, leveling kit, 3'' body lift, and 35 by 12.5 tire. will it look good or bad on a 97 f150.

 

It will look fine. However, I'd stay away from the leveling kit because you don't need it. Just crank up your torsion bars with the OEM adjustment keys. The aftermarket torsion bar adjustment keys (aka leveling kit) just allow you to put way too much preload on your torsion bars which will destroy your ride quality and lead to premature CV and ball joint wear.
