Configured with FOX 2.0 Adventure Series shocks, featuring an internal floating piston (IFP) monotube design, a large 5/8-inch hard chrome plated heat-treated alloy steel shaft, race-developed high-flow piston design, application-specific valving for maximized performance, and a long-lasting silver coated finish.
Overview
Zone Offroad's Reinforced Radius Arm Bracket Kits are designed to restore proper suspension geometry and improve ride quality on 2023–2026 Ford F-250 and F-350 Super Duty trucks (single rear wheel models). Engineered for strength and precision, these heavy-duty drop brackets correct axle rotation to return caster to factory specifications, improving steering stability, handling, and tracking on lifted vehicles. By lowering the radius arm mounting points, the system helps eliminate coil bowing and ensures the coil springs are seated correctly. Available with your choice of Zone Nitro twin-tube shocks or FOX 2.0 Adventure Series shocks.

- Two-piece rear drive shaft? Add a carrier bearing drop kit to reduce post-lift driveline angles and avoid/eliminate driveshaft vibration.
- Some 2023 F-250/F-350 Super Duty trucks from Ford have left rear axle shafts manufactured without proper completion. Refer to Ford Safety Recall 23S49 for details and affected build range.
- Fits SRW (single rear wheel) models only.
- Due to taller factory ride height, Tremor models will not net full advertised lift height. Final ride height will be the same as standard models.
- Larger tires on stock wheels are not recommended due to interference with brake line, radius arm, and sway bar. Use recommended specs listed in the wheel and tire fitment section.
- 2023+ F-250/F-350 Super Duty trucks equipped with Load Scales/Ride Height Sensors will require ZONF5502 to properly remount the sensor linkages.
- Recalibration of your vehicle's Advanced Driver Assistance System (ADAS) cameras, radars, LiDAR, and other sensors may be necessary by your local dealership or ADAS service center following installation. This ensures proper functionality of lane keeping, lane departure, parking assistance, blind-spot detection, adaptive cruise control, and other systems. All charges and expenses that may occur from dealership calibrations and adjustments are the sole responsibility of the vehicle owner.
