Camburg Engineering Radius Arm Kit

Camburg Engineering Radius Arm Kits: Race-Born Engineering for the Street and Trail

When a leveling kit or suspension lift changes the geometry of your truck's front end, the factory radius arms are often the weakest link left in the system. Camburg Engineering — the Huntington Beach, California suspension specialist with roots deep in desert racing — engineered their Uniball Radius Arm Kits specifically to solve that problem for owners of lifted and leveled Ford trucks.

Founded in 1997 by Jerry Zaiden and Jason Campbell after years of experience in the off-road racing and manufacturing industries, Camburg's initial goal was to offer products and services that were only available to elite off-road racing teams. That philosophy carries directly into their Radius Arm Kits — components engineered to the same standard as what Camburg fields in competition.

What Sets Camburg Radius Arms Apart

The Camburg Engineering Uniball Radius Arm Kit is a direct bolt-on upgrade designed to replace the weak factory arms, correcting and increasing positive caster, improving suspension movement, and providing better on-road stability. For Ford Super Duty owners who have installed a leveling or lift kit, that wandering steering, sketchy braking, or "death wobble" isn't imaginary — it's the factory radius arms struggling to work properly with leveled or lifted suspensions.

The engineering behind Camburg's solution goes well beyond a simple swap. Camburg uses a boxed 3/16" steel design that improves ground and tire clearance, plus FK heat-treated 1" uniballs that move smoothly with zero flex under braking. By using a 1" FK uniball, the kit gains wheel travel and eliminates the flex or deflection found with rubber or polyurethane bushings — and they last longer, allowing the suspension to cycle smoother and bind-free.

These arms are engineered to be much stronger than the thin stock radius arms, with stronger shock mounts that are double-sheared and an additional limit-strap tab, using thick-walled DOM tubing and laser-cut thick plate work top and bottom — with the front and uniball areas boxed in for even more strength.

CAD-Designed, Race-Tested Construction

The radius arms are CAD designed, laser cut, CNC formed, MIG welded, sandblasted, and powder coated in Camburg's trademark gray, ready to install with all necessary hardware included. The arms bolt directly into the factory mounts, and for 2008–2022 Super Duty models, Camburg provides bracketry and hardware to correct sway-bar geometry as well.

Camburg corrects suspension geometry by increasing positive caster for better handling and stability both on and off-road, with the kits designed to work with 3–5" of lift from a coil spring or coilover. These are the same uniball radius arms Camburg uses in their Baja and Trail Series kits — meaning the technology trickles directly down from race-proven platforms to street-ready hardware.

Not many other companies design, build, and race on their own components — and this sets Camburg apart as a brand that establishes the trend rather than following it. For truck owners who refuse to compromise on suspension integrity after a lift, Camburg Engineering's Radius Arm Kits represent a purpose-built upgrade with a genuine racing pedigree behind every weld.
