Ford OBS Axle Conversion Kit (05+ Superduty Swap)


This is our entry level 05+ Superduty Axle Conversion Kit which was designed to use all the factory parts from the Superduty suspension and steering to keep things and simple as possible. All our brackets are bolt in and locate from existing holes in the frame. 

Add the Driveshaft Conversion U-Joints to bolt your OBS Driveshafts up to the Superduty Axles 

Upgrade your 05+ Superduty Axle Swap by replacing the radius arms with our Short Arm 4 Link Kit! The 4-link conversion offers improved stability, strength and caster control during wheel travel.

If you have a ZF5 Transmission you will need to use our ZF5 Crossmember
