LINK ARMS & BRACKETS
2″ OD Heavy wall link arms have 1/4″ thick steel brackets on the axle side with adjustable alignment cams to dial in the caster for the new ride height. Fabtech’s legendary 5 Ton joints® are used on the frame pivot side for superior strength. The 5 Ton joints® have been proven in military use for over 10 years and come with a lifetime warranty against wearing out.
The 4 Link Arms attach to 1/4″ thick steel frame brackets that integrate into the factory Radius Arm brackets for a solid mounting of the new suspension.
The geometry of the 4 Link arms and frame brackets has been designed to provide an improved highway ride due to reduced caster change and able to tackle rough offroad conditions better than a Radius Arm suspension.
hot wound coils have been designed for a very compliant ride quality both on and offroad. Each coil is preset during the manufacturing process to insure no ride height settling over time. Allows for a 2″ increase in wheel travel over stock when used with Fabtech shock absorbers.
TRACK BAR BRACKET
1/4″ thick steel bracketry repositions the factory track bar to center the axle under the vehicle with the increased lift height. Super stout box style bracket is designed to eliminate deflection when the track bar moves through its full cycle.
DROPPED PITMAN ARM
Forged steel construction with high strength material that exceeds the factory specifications. Designed specifically for the Ford Super Duty to work in conjunction with the factory drag link and Fabtech’s Track Bar bracket for proper steering functionality.
FRONT BUMP STOP BRACKETS
Heavy duty 1/4″ thick steel brackets extend the factory bump stop cushions down to eliminate over cycling of the suspension. The bracket’s semi boxed construction can handle the full impact compression of the massive Super Duty.
SWAY BAR BRACKETS
1/4″ thick steel drop brackets re-position the front sway bar for the increased ride height. This allows the sway bar link ends to fully cycle without binding throughout the extended travel range.
BRAKE LINE BRACKETS
Re-positions the factory brake lines down on the frame for the new travel range without having to open the brake system. Keeps factory fluid system intact.
STEERING STABILIZER BRACKETS
Retains the stock Ford heavy duty steering stabilizer with a 1/4″ thick steel bracket and support brace to help reduce tire shimmy.
A single leaf is inserted into the spring pack to provide an additional 1.5″ of rear lift with a double pin configuration for strength.
REAR LIFT BLOCKS
Cast iron rear lift blocks with an integrated bump stop replaces the stock blocks for additional lift without changing the ride quality of the factory rear suspension or load carrying capacity.[/x_accordion_item]
