2017-22 Ford F250/F350 4WD
Fabtech’s Radius Arm system for the Ford Super Duty is built to handle the on and offroad demands of the truck enthusiast. This system is a complete upgrade to the factory suspension and will provide additional strength for use with oversized tires.
The heart of this quality system is Fabtech’s tubular Radius Arms. The design of these arms comes from Fabtech race components built with a tubular structure reinforced by a dimple die side plate and heavy gusseting for rugged offroad use. They are an outstanding upgrade to the stock stamped arms.
This Radius Arm design has been proven in over 10 years of service in military applications. High quality components with properly designed suspension geometry is what sets this system apart from all other Radius Arm suspensions. System includes a free 5 year 60,000 mile powertrain warranty.
Included with this system is Dirt Logic 2.25 Stainless Steel reservoir shocks in the front and non reservoir shocks in the rear. These Dirt Logic shocks have been ride tuned to the vehicle with the Fabtech Coil Springs and oversized tires for an excellent ride quality both on and offroad.
Each Fabtech component has been designed with specific features and benefits that create this quality suspension system. For a greater understanding of each these components, please see below.

Tubular construction with dimple die side plate for superior strength. Arms are offset for full turning radius with 15.50 wide tires on 5″ back space wheels. Radius Arms have 2 degrees of caster built in for the increased ride height. Adjustable alignment cams on the arms allow for an additional 1.5-2 degrees of caster adjustment.
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.
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.
