Fabtech’s legendary Radius Arms provide a significant upgrade for the front suspension of 2014–2024 Ram 2500 4WD and 2014–2018 Ram 3500 4WD models equipped with lift systems from 2.5″ to 7″. Designed for heavy-duty performance, these tubular Radius Arms deliver superior strength and a race-inspired appearance suitable for aggressive off-road use.
Each arm includes an additional 1 degree of caster built into its design. When combined with the easy-to-adjust alignment cams, the system offers a total of 2 degrees more caster than stock. This added caster is especially beneficial for lifted trucks running oversized tires, as it helps improve highway stability and overall driveability.
The upper and lower sections of the arms are constructed from 1.75″ OD x .120″ wall DOM tubing, fully welded to prevent moisture intrusion and resist corrosion. A dimple-die side plate reinforces the structure, adding rigidity while minimizing weight. The arms are offset and positioned inboard compared to factory radius arms, providing full steering clearance when using 13.50" wide tires with 5" backspace wheels.
The open design of Fabtech’s Radius Arms allows for complete powdercoat coverage, offering better corrosion protection than boxed, stitch-welded arms that can trap moisture and develop rust. With over 15 years of proven performance in consumer, commercial, and military applications, Fabtech Radius Arms remain the industry benchmark for strength, durability, and dependability.
