Superlift Superunner Steering System Conversion Kits

Superlift's award-winning steering system is available for all vehicle models equipped with Ford's Twin Traction Beam (TTB) suspension. It consists of a centerlink, an idler arm and mounting bracket, and two tie rod assemblies. The system is compatible with most name brand 4 in. to 6 in. lift kits. The vehicle must be lifted no less than 3.5 in. and no more than 6 in.—plus be equipped with a Superlift brand dropped pitman arm (purchased separately). This Superunner Steering Conversion kit works with Superlift Suspension lift kits associated with Ford applications.

Fords with TTB suspension are known for their somewhat vague steering feel. On off-camber or less-than-ideal driving surfaces, continuous corrective steering input is required to keep the vehicle pointed straight. When the vehicle is raised, these inherent tendencies are magnified. To correct this concern, you must: (1) minimize tie rod angles, and (2) improve steering tie rod-to-axle beam "phasing" ... the tie rods' arc of movement should better match the axle beams' arc of movement.

These two factors greatly impact drivability. When this geometry is askew, the vehicle experiences excessive toe-in/toe-out variations as the suspension travels, resulting in the Ford TTB version of bump-steer.

Superlift offers two methods to improve steering traits. Their dropped pitman arm reduces some of the additional steering linkage angle created by increased ride height. The pitman arm, used with a Superunner Steering System, further reduces tie rod angles. The new tie rod assemblies, more proportional in length to the axle beams, improve phasing.

On most lifted Fords, installing a Superlift dropped pitman arm alone will result in satisfactory steering characteristics. The dropped arm, used in conjunction with their Superunner Steering System, delivers optimum steering traits.
