This family of Fords uses a two-piece front axle, coil springs, and radius arms. Ford calls this version of IFS their Twin Traction Beam (TTB) suspension. As front ride height is raised, the tops of the tires lean outward creating positive camber angle. With lifts over 2", caster angle must also be addressed. Correction is handled by lowering the stock radius arms. For taller lifts, new axle-to-crossmember lowering brackets restore camber. It may be necessary to replace the stock eccentric camber bushings to precisely dialin camber angle.

The Superunner Long-Arm radius arms offer caster correction plus additional benefits. The arms are considerably longer than stock and increase the amount of usable bind-free extension travel. This makes it easier for the tires to travel independently and stay in contact with the road or trail surface. The longer arms also reduce the degree of caster change the vehicle experiences as the suspension goes through its travel cycle. These factors combine to improve overall driveability and ride quality. You will experience a noticeable difference both on and off-road.

Our dropped pitman arm reduces some of the additional tie rod angle created by the lift. The new steering system uses a centerlink to further reduce tie rod angles, and the new tie rods are more proportional in length to the axle halves. The result is steering linkage that is more in phase with the suspension.
