ICON 2023-2026 Ford F-250/F-350 Super Duty 4WD Radius Arm Drop Kit

The ICON Radius Arm Drop Kit is a bolt-on bracket system engineered for 2023–2026 Ford F-250 and F-350 Super Duty 4WD trucks running ICON 4.5" lift suspension systems, allowing the retention of stock or aftermarket radius arms without cutting or welding.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Geometry Correction Built Into the Bracket

When a Super Duty is lifted, the radius arm angle steepens, pulling caster out of spec and introducing handling vagueness on and off pavement. The ICON Radius Arm Drop Kit repositions the radius arm mounting point to reduce that angle and restore caster geometry, so the truck steers predictably at highway speed and tracks straight under load.

Fabricated to Handle Aggressive Off-Road Use

Each bracket is CNC laser cut and brake-formed from steel plate, then finished in a semi-gloss black powder coat for corrosion resistance. The fabrication process produces tight tolerances and consistent geometry across the kit: repeatability that matters when a bracket is absorbing the shock loads of washboard roads and rocky terrain.

No Cutting, No Welding, No Fabrication Required

Installation is 100% bolt-on. The brackets are application-specific to the 2023–2026 Super Duty platform, so mounting points align without modification to the frame or existing radius arm hardware. Builders who want to retain their stock radius arms, or who have already invested in aftermarket arms, can run either without compromise.

Features

• Application-specific fitment: designed exclusively for 2023–2026 Ford F-250/F-350 Super Duty 4WD
• 4.5" lift compatibility: drops radius arms for use with ICON 4.5" lift suspension systems
• Caster correction: reduces radius arm angle to aid in caster restoration after lift
• Stock or aftermarket arms: accommodates both without modification
• CNC laser cut and brake-formed steel plate: fabricated for structural consistency and off-road durability
• Semi-gloss black powder coat: corrosion-resistant finish
• 100% bolt-on installation: no cutting or welding required

Specifications

Who This Is For and Isn't

This kit suits owners of 2023–2026 Ford F-250 or F-350 Super Duty 4WD trucks who are installing or have installed an ICON 4.5" lift system and want to retain their stock or aftermarket radius arms with corrected caster geometry.

This kit does not fit 2WD Super Duty models. It is designed for use with ICON 4.5" lift suspension systems and is not confirmed for use with other lift heights or non-ICON suspension systems.

Common Questions

Will this kit work with my existing aftermarket radius arms?

Yes. The ICON Radius Arm Drop Kit is designed to accommodate both stock and aftermarket radius arms on 2023–2026 Ford F-250/F-350 Super Duty 4WD trucks, so builders who have already upgraded their arms do not need to swap back to stock to use this kit.

Does installation require cutting or welding the frame?

No. The Radius Arm Drop Kit is a 100% bolt-on system. The brackets are application-specific to the 2023–2026 Super Duty platform, so no frame modification, cutting, or welding is required during installation.

What lift height is this kit designed for?

The ICON Radius Arm Drop Kit is engineered specifically for use with ICON 4.5" lift suspension systems on the 2023–2026 Ford F-250/F-350 Super Duty 4WD. It is not confirmed for use with other lift heights or non-ICON suspension systems.

Does this kit address caster correction after lifting?

Yes. By dropping the radius arm mounting point, the kit reduces the steepened radius arm angle that results from lifting the Super Duty, which aids in restoring caster geometry for improved on-road handling and straight-line tracking.
