Description

2017-22 Ford F250/F350 4WD

Fabtech’s 4" Radius Arm lift kit has been built for the Ford Super Duty to handle the on and offroad demands of the truck enthusiast. This system is a heavy duty upgrade to the factory suspension and will provide additional strength to the vehicle.

The heart of this high quality lift kit is Fabtech’s legendary tubular Radius Arms. The tubular structure design is the combination of our extensive offroad racing history and our desire to provide a smooth, compliant driving experience. The result is a suspension system with superior strength that can handle rugged offroad terrain and still navigate a grocery store parking lot with ease.

The front suspension receives Fabtech’s replacement coil springs that have been developed for a great ride on and off road.

The redesigned Radius Arms have a new side plate and bold laser cut logo that gives them a modern aggressive look that will turn heads as you tackle the toughest offroad terrain.

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.

RADIUS ARM

Redesigned tubular construction and side plate provide superior strength and modern aggressive look. The arms are offset for full turning radius with 12.50 wide tires on 5″ back space wheels. Adjustable alignment cams on the arms allow for an additional 1.5 degrees of caster adjustment.

COIL SPRINGS

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.

REAR ADD-A-LEAF

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.

REAR U-BOLTS

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.
