2017-22 Ford F250/F350 4WD
Fabtech‚Äôs 4‚Äù 4 Link Conversion System for the Ford F250/F350 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 near zero 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.
The front suspension receives the finest shock upgrade on the market with the Dirt Logic 4.0 Coilover conversion. It will provide outstanding damping capacity offroad with a quality on road ride. This Coilover bolts in place of the factory coil spring without removal of the coil spring bucket. The Dirt Logic is constructed with a stainless steel body for maximum corrosion resistance. It comes with a giant 4" diameter aluminum remote reservoir that mounts horizontally above the Coilover to allow for full compression travel with oversized tires.
The rear suspension receives a 5" lift block, extended bump stop brackets and Dirt Logic 2.25 shocks for a balanced ride quality.
This 4 Link system with the Dirt Logic 4.0 Coilovers is the pinnacle of all Super Duty suspension systems for owners that demand the best.
System includes a free 5 year 60,000 mile powertrain warranty.

LINK ARMS & BRACKETS
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.
DIRT LOGIC 4.0 CONVERSION
Simplistic super stout 1/4" thick steel brackets utilize the factory coil bucket to bolt in the big Dirt Logic 4.0 Coilover. A massive 4" diameter stainless steel body with 1.25" NitroSteel® piston rod for maximum corrosion resistance and durability for the most aggressive driving conditions. coil springs handle the weight of the Super Duty while providing 2" of increased wheel travel over stock. The remote aluminum reservoir dissipates heat for consistent damping when driving over extreme terrain at high speed. The ultimate of all coilover shocks.
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 & REAR 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.
REAR LIFT BLOCKS
Cast iron 5" rear lift blocks provide lift without changing the ride quality of the factory rear suspension or load carrying capacity.
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.[/x_accordion_item][/x_accordion]
