About this product
Set Axle Position and Caster for Your Lifted Super Duty
The APOC Industries 4-Link Conversion Kit replaces the factory radius-arm layout with independently adjustable upper and lower control arms. Set axle position and caster to suit your build rather than relying on the factory layout to accommodate your lift.
Designed for 2005–2022 Ford F-250, F-350, and F-450 Super Duty with 2.5–10 inches of lift. The main control-arm bodies are constructed from 1/4" steel plate. DOM tubing is used only at the bushing ends, not as the main arm construction. Polyurethane bushings and grease fittings provide a serviceable suspension setup.
Adjustment Beyond the Factory Setup
The upper and lower arms adjust independently, allowing axle position and caster to be set separately. A supplied lower-arm alignment cam bolt provides easy fine-tuning during alignment, adding an adjustment feature Ford did not provide in the factory setup.
