Ford F250/F350 Super Duty 2023-2026 4WD Radius Arm Kit (for 2.5" to 6" lifts) by Fabtech

Upgrade your Ford F-250, F-350, F-450, or F-550 Super Duty 4WD (Diesel) with Fabtech’s FTS22384 tubular Radius Arms—built for strength, precision, and style. Featuring a side plate with a bold laser-cut logo, these arms deliver a modern, aggressive look while offering serious performance for lifted trucks running 2.5", 4", or 6" suspensions.

The heavy-duty tubular construction enhances rigidity and durability, giving your Super Duty the strength it needs to handle demanding off-road conditions. Designed for aggressive terrain, these radius arms combine a rugged, race-inspired design with engineering that enhances alignment geometry and handling at lifted ride heights.

Each arm adds 1 degree of caster built into the design, and when combined with the included adjustable alignment cams, provides up to 1.5° of additional caster compared to stock—a key benefit for maintaining straight-line stability and tracking on the highway.

Built from 1.75" OD x .120" wall DOM steel tubing, these arms are fully welded and closed for corrosion protection. Their offset, inboard positioning allows full steering lock with 13.50"-wide tires on 5" backspace wheels, ensuring maximum tire clearance even under flex.

Fabtech’s open design allows for full powder coat coverage inside and out—unlike boxed, stitch-welded arms that can trap moisture and rust over time. Proven for over 20 years in consumer, commercial, and military applications, these are the toughest, most refined radius arms available for your Super Duty.
