PAbronco, welcome to Bronco Zone!!! Your question is asked often, and really depends on the condition of your Bronco, the type of driving you plan to do, and of course your budget. As i see it, you have three options:
Body Lift - this kit like the one you posted from BG uses spacers to lift the body off the frame by 2-3 inches. Advantage is cost saving vs a suspension lift, disadvantage is no gain in ground clearance except that achieved by larger tires. A body lift requires re-location of many items, such as the radiator fan shroud, front & rear bumpers, along with sterring shaft, transmission and transfer-case linkage extensions. Typical cost is $100 plus $500 installation.
Suspension lift - this kit involves re-locating the radius arm and axle i-beam mounting points thru drop brackets in order to maintain steering geometrty in conjunction with a dropped Pitman arm, along with longer coil springs, longer shocks, rear blocks or lifted rearsprings, and re-location or extension of the brake lines. Advantage is more wheel travel and ground clearance, disadvatage is cost. Typical cost of a 4" kit is $500 plus $500 installation.
Fender trimming - this mod is free! You simply cut out part of the fender opening to allow for larger tires. Dependings on the tire size you want to run, you ca neither trim the ends of the openings, or may need to trim 2-3 inches all the way around the openings front and/or rear to prevent tire rub with the fender.
In regard to the SST kit link you posted, I do not see a listing for 1980-1996 F-150/ Bronco. Most of those style of kits are designed for IFS axles and use a coil spring. strut or shock spacer to achieve lift, or a change in the torsion keys. AS an aexample, I am running Ford torsion keys on my 98 GM Z-71, as they provide a 2" lift for the front only. To achive similar results on your 80-96 Bronco, you have the choice of leveling coils (2" taller than stock) or coil spring spacers. I do not condone spacers under the coil springs or the leveling coils as they tend to encounter more alignment problems. But that should get you thinking along the lines of what may work best for you, JSM84
