Getting Some Ground Clearance Out Of A Bronco Or F-150
The '80-to-'96 twin traction beam (TTB) Ford half-ton truck is now three generations outdated, but it still remains extremely popular in the off-road scene. In fact, Ford still uses the 2WD version of this suspension on its vans and Super Dutys to this very day.
The TTB was an excellent cross of independent and solid-axle suspension technologies combined to make one hard-to-beat system (in the dirt). The TTB is simple to modify for lots of travel, but it does have one downfall: its handling characteristics are not stellar because of the camber change the beams undergo as the suspension oscillates (and the more travel the TTB has, the more the camber changes).
Nevertheless, enthusiasts have found the camber change a small price to pay for a heavy-duty, high-travel, off-road worthy suspension.
Rough Country's standard 4- and 6-inch kits take advantage of all the attributes of the TTB suspension and improves it even further by adding some extra travel, and by doing it for less than $500! That's right-an entire suspension that you can purchase with less than a full paycheck.
