Restores critical steering geometry and eliminates axle-tracking instability on diesel-equipped 2023 Ford F-250 and F-350 trucks with 4.5-inch suspension systems.

Designed specifically to counteract the factory-heavy rear droop of Super Duty diesels, this radius arm drop kit bridges the gap between lifting and reliable daily driving. It corrects pinion angles, re-centers the tracking axis, and prepares your rig for aggressive trail use without compromising OEM durability.

• Corrects Diesel-Specific Droop: Lowers the front radius arm mounting points to match the massive weight bias of the diesel platform, preventing speed wobbles, uneven tire scrubbing, and component fatigue.
• Heavy-Duty Load Management: Constructed from precision-formed steel brackets and sealed pivot bushings rated for maximum payload capacity, ensuring consistent alignment under full towing loads.
• Extended Range Compatibility: Engineered to work seamlessly with the 4.5-inch lift profile, allowing safe clearance of up to 37x12.50-inch tires with minor fender trimming while keeping factory suspension travel intact.
• Streamlined Brake Integration: Maintains proper hose routing geometry; extended brake line kits are recommended for single rear wheel configurations that require additional slack.
• Anti-Corrosion Protection: Multi-cycle surface finishing shields exposed welds and fasteners from road salt, mud slurry, and off-road moisture, extending service life in harsh environments.

Exclusive application: 2023 Ford F-250 and F-350 Super Duty 4WD Crew Cab Diesel models only. Will not fit non-diesel variants, Tremor packages, Cab & Chassis configurations, or 4x2 drivetrains. May require an adjustable track bar to fine-tune left-to-right axle alignment. Direct bolt-on design replaces stock mounting hubs without custom fabrication.
