YOU MUST HAVE AT LEAST 4 INCHES OF LIFT TO USE THIS 4-LINK KIT

No welding required minor drilling only.

The Ford f-250 / 350 Superduty 4 link conversion kit allows easy adjustments to a caster angle and axle centering in fender wells. When running a leveling kit or more lift, the axle is no longer centered in the fender like stock. Adjustable control arms allow you to center the axle back to the stock location, which helps to reduce or stop tire rubbing when turning. The four-link conversion kit control arms are adjustable to allow for caster angle changes to correct steering geometry after a lift has been installed.

Apoc Ford Superduty, four Link conversion kits, are a significant upgrade from stock. Factory radius arms work great with factory-sized tires and suspensions, but once you get bigger, you need more robust and longer control arms to maintain correct handling. Apoc Ford Super duty four-link kits are 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 4 link conversion kits are fully adjustable from 4 inches of lift to 10" of lift, so if you're starting with a small lift for now but upgrading later, these arms will suit your needs as you add more lift over time.

 Control Arm lengths 

If upgrading from factory control 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 unsure, contact the lift kit manufacturer to verify your 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 proper alignment angles.
