FABTECH 2011-16 8" 4 Link System w/ Front Dirt Logic 4.0 Resi Coilovers & Rear Dirt Logic Shocks -Ford F250/F350 4WD
Fabtech’s 4 Link Conversion system for the Ford Super Duty has been designed to provide improved on road performance with the ability to tackle the most rugged offroad terrain. This high end system is a bolt on replacement to the factory Radius Arm suspension and comes with everything needed to convert to a 4 Link front suspension.
The system will provide less caster change throughout the travel range which benefits on road driving. Offroad the 4 Link system will provide more articulation than a Radius Arm for increased terrain traversing at all speeds.
Included in this system is the massive Dirt Logic 4.0 Coilover Conversion for outstanding damping capacity offroad with a quality on road ride. The Coilover bolts in place of the factory coil spring without removal of the coil spring bucket. The giant 4" diameter aluminum remote reservoir mounts horizontally above the Coilover to allow for full compression travel with oversized tires. The Dirt Logic 4.0 Coilover is the biggest and baddest on the market for the Ford Super Duty.
Fabtech’s 4 Link System has been proven in over 10 years of service in military applications. High quality components with properly designed suspension geometry is the pinnacle of Super Duty suspension systems. System includes a free 5 year 60,000 mile powertrain warranty.
Each Fabtech component is expertly built in house and has specific design features and benefits as listed below.
Link Arms and 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.
Dirt Logic 4.0 Conversion
Simplistic super stout 1/4" thick steel brackets utilize the factory coil bucket to bolt in the massive Dirt Logic 4.0 Coilover. A 4" diameter stainless steel body with 1.25" NitroSteel piston rod provides maximum corrosion resistance and durability for the most aggressive driving conditions. American made 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.
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 late model 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 compression impact of a 7000 Lb. Super Duty.
Sway Bar Brackets
1/4" thick steel drop brackets reposition 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
Repositions 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.
Driveshaft Shim Kit
Allows for incremental rear driveline angle change at the carrier bearing on two piece driveshaft applications to eliminate vibration with the increased ride height. Rear Leaf Springs High quality Canadian spring steel creates this 4 leaf pack with a bottom overload leaf to handle heavy cargo with excellent flexibility. Each leaf has a tip liner to reduce friction along with vulcanized spring eye bushings to provide a smooth quiet ride.
Rear Sway Bar Brackets
Brackets reposition the sway bar end links down on the frame for the new ride height allowing for proper sway bar functionality without binding.
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 Rear 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.
