Radius Arms – FTS23232



2014-22 Ram 2500 4WD

2014-18 Ram 3500 4WD

Fabtech’s legendary Radius Arms are the perfect upgrade to the Ram 2500 and 3500 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 Ram Radius Arms directly replace the factory arms for use with lifted 2.5" to 7" 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 2 degrees more caster than stock. A big benefit for lifted vehicles to improve highway drive ability with oversized tires.

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. Spanning between the tubes is a dimple die side plate that adds rigidity to the arm for strength with minimal weight gain.
The Ram 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 Ram 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 inside and cause rust.

Fabtech’s Radius Arms have been proven for over 15 years in consumer, commercial and military applications. There are no better Radius Arms for your Ram.
