ICON Radius Arm Drop Kit for 2005-2010 Ford F-250/F-350 Super Duty 4WD

The ICON Radius Arm Drop Kit (SKU 64040) is a bolt-on suspension component for 2005–2010 Ford F-250 and F-350 Super Duty 4WD trucks, designed to allow stock or aftermarket radius arms to function correctly with ICON 4.5"–7" lift suspension systems. The kit ships as a set of fabricated steel drop brackets and installs 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.

Correct Geometry at Lift Height

When a Super Duty is lifted 4.5"–7", the factory radius arm angle steepens in a way that degrades caster and accelerates wear on steering and front-end components. The ICON Radius Arm Drop Kit lowers the radius arm mounting point to reduce that angle, restoring caster geometry closer to factory spec. The result is more predictable steering feel and reduced stress on the radius arms themselves, whether those arms are the factory units or an aftermarket set.

Fabricated Steel Construction with a Durable Finish

Each bracket is CNC laser-cut and brake-formed from steel plate, a process that holds tight tolerances on the mounting surfaces that matter most for geometry accuracy. A semi-gloss black powder coat finish provides corrosion resistance for brackets that live in the exposed undercarriage environment of a truck used off-road.

Bolt-On Installation, No Fabrication Required

The kit is 100% bolt-on: no cutting, no welding, and no frame modification. That keeps the installation within reach of a capable home builder with basic hand tools and a lift, and it means the truck's frame remains unmodified if the kit is ever removed.

Specifications

Who This Is For and Isn't

This kit suits owners of 2005–2010 Ford F-250 or F-350 Super Duty 4WD trucks who are running or planning to run an ICON lift system in the 4.5"–7" range and need to retain their stock or aftermarket radius arms with corrected geometry.

This kit does not fit two-wheel-drive Super Duty trucks, Super Duty trucks outside the 2005–2010 model years, or lift systems outside the 4.5"–7" range it is designed for. It is not a standalone lift kit and does not include shocks, springs, or other suspension components.

Common Questions

Does this kit work with radius arms other than ICON's own?

The ICON Radius Arm Drop Kit is designed to fit both stock Ford radius arms and aftermarket radius arms on 2005–2010 F-250/F-350 Super Duty 4WD trucks, so it is not limited to ICON-brand arms.

Is cutting or welding required to install this kit?

No. The Radius Arm Drop Kit is a 100% bolt-on installation: no cutting, welding, or frame modification is required. An installation guide is available for reference.

What lift range is this kit designed for?

The ICON Radius Arm Drop Kit is engineered specifically for use with ICON 4.5"–7" lift suspension systems on the 2005–2010 Ford F-250/F-350 Super Duty 4WD platform. Compatibility with other lift heights or brands is not stated.
