Radius Arms – FTS22384

SKU: FTS22384 Categories: , , Tag:



2023-24 Ford F250/F350/F450/F550 4WD [Diesel]

Fabtech’s 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. These Radius Arms are the perfect upgrade to the Ford Super Duty front suspension for lifted applications. The heavy duty tubular construction adds strength with a race component style to the vehicle for aggressive offroad use.

These Super Duty Radius Arms directly replace the factory arms for use with lifted 2.5", 4" and 6" suspensions. The arms have an additional 1 degree of caster built into the arms and with the easy adjustment alignment cams gives a total of 1.5 degrees more caster than stock. A big benefit for taller lifted vehicles to improve highway tracking.

The upper and lower tubes of the arms are constructed with 1.75" OD x .120" wall DOM tubing and are fully welded closed to prevent corrosion. Radius Arms are offset and positioned inboard compared to the stock arms to allow full steering lock with a 13.50 wide tire on a 5" backspace wheel.

The Fabtech Super Duty Radius Arms are an open design so that powdercoat can cover the entire arm. This design is superior in coating coverage compared to boxed arms that are stitch welded and have gaps that allow moisture to get in and cause rust.

Fabtech’s Radius Arms have been proven for over 20 years in consumer, commercial and military applications. There are no better Radius Arms for your Super Duty.
