FABTECH 2017-22 Ford F250/ 350 4WD-8″ 4 LINK SYSTEM W/ DIRT LOGIC 2.25 SHOCKS
Fabtech’s 8″ 4 Link Conversion System for the Ford Super Duty is designed to provide maximum suspension performance for both on and offroad use. The system replaces the factory Radius Arm suspension with heavy duty 4 Link components for increased strength and functionality. The system will provide less caster change throughout the travel range which benefits on road driving. When offroad the 4 Link system will provide more articulation than a Radius Arm for increased terrain traversing at all speeds.
- 2″ OD Heavy Wall Links
- Fabtech Heavy Duty 5 Ton Joints®
- Track Bar Relocation Bracket
- Extended Length Track Bar
- Sway Bar Drop Brackets
- Pitman Arm Rear Block & U-bolt Kit
- Rear Add-a-leaf Kit
Unique to this 8″ system is Fabtech’s extended length Track Bar to address the hyper sensitive steering box of the late model Super Duty. Fabtech is the only manufacturer with this exclusive system that offers proper steering performance. Fabtech’s extended length Track Bar is 4″ longer than stock and is offset to the driver side with a stout 1/4″ thick steel mounting bracket. This design helps keep the Track Bar and Draglink closer to parallel than the factory angles to reduce push in the steering.The Track Bar allows for full lock steering of 15.50 wide tires w/ 4 3/4″ BS wheels.
Fabtechs 4 Link System has been proven in over 10 years of service in rugged commercial and military applications to ensure long life on your daily driven vehicle.
High quality components with properly designed suspension geometry makes this Super Duty system the pinnacle of all suspensions. Comes with a free 5 year 60,000 mile powertrain warranty
For a complete understanding of this high quality system please see below features and benefits by component.
LINK ARMS & BRAKETS
2″ OD Heavy wall link arms have 1/4″ thick steel brackets at the axle with adjustable alignment cams and Fabtech’s legendary 5 Ton joints to pivot at the frame for an extended service life. The 5 Ton joints have been proven in military use for over 10 years and are quiet and strong. The 4 Link Arms attach to stout 1/4″ thick steel frame 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.
American made coil springs 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.
EXTENDED LENGTH TRACK BAR & BRACKET
This unique design features an offset, extended length adjustable Track Bar to address the hyper sensitive steering box of the late model Super Duty when running oversized tires.
The Track Bar is built of 1.50 OD .375 wall DOM tubing and is 4″ longer than stock. The Track Bar is attached to the frame with a 1/4″ thick frame bracket that is offset to the driver side with a support brace to eliminate deflection. A 15.50 wide tire on 4 3/4″ backspace wheel will still turn full lock without interference.
The extended length Track Bar is re-positioned to be closer to neutral with the factory drag link than stock. This change results in reducing tire shake and bump steer far more effectively than with just a Track Bar bracket. A Fabtech exclusive.
DROPPED PITMAN ARM
Forged steel construction with high strength material that exceeds the factory specifications. Designed specifically for the Super Duty to work in conjunction with the factory drag link and Fabtech’s extended length Track Bar 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 5.75″ rear lift blocks with an integrated bump stop replace the stock blocks for additional lift without changing the ride quality of the factory rear suspension or load carrying capacity.
American made U-Bolts designed to attach the entire rear differential to the vehicle. A critical part that demands the best quality for your vehicle.
DIRT LOGIC 2.25 SHOCKS
Constructed of a stainless steel body with NitroSteel® piston rod for maximum corrosion resistance and durability. Superior ride quality both on and offroad. Excellent damping for offroad use.
