2005-2022 Ford Superduty F-250/350/450 Adjustable Radius arm stock to 6" lift
Designed to be used on a stock to 6" of lift
The Ford F-250/350/450 Superduty RADIUS kit allows easy adjustments to a caster angle and axle centering in fender wells. When running a leveling kit or lift, the axle is no longer centered in the fender like stock. Adjustable radius arms allow you to center the axle back to stock location, which helps to reduce or stop tire rubbing when turning. Apoc's radius arms are adjustable to allow for caster angle changes to correct steering geometry after a lift has been installed.
Apoc Ford Superduty Adjustable Radius arms are a significant upgrade from stock. Factory radius arms work great with factory-sized tires and suspension, but once you go bigger, you need more robust and longer control arms to maintain correct handling. Apoc adjustable radius is built to support proper suspension and steering geometry to keep your truck feeling like stock but better. When adding any amount of lift to a Ford Superduty, you change your caster angles which can create dangerous steering symptoms and make it harder to maintain proper wheel tracking, which can cause your vehicle to wander between the lines easier. Big tires and lifts look great but don't sacrifice handling and create a beast to keep on the road. Upgrade your control arms and drive with ease. Apoc Industries radius arms are fully adjustable from stock to 6" of lift, so if you're starting with a mild lift for now but upgrading later, these arms will suit your needs as you add more lift over time.

Radius Arm length
If upgrading from factory radius arms, ensure you set the length to the correct lift size to keep your steering geometry accurate. The larger the lift, the longer the control arms. Don't assume your lift size; if you are unsure, contact the lift kit manufacturer to verify your lift size. The Instructions will give you the measurements to set each control arm to match your lift; an alignment is recommended after installation to ensure all alignment angles are proper.
