Our kit will greatly improve the handling of your Superduty over the factory radius arm. With our design, positive caster is maintained through the travel of the suspension. That's very important for a firm and confident feel over rough roads and terrain. Stock radius arms can go into negative caster which leads to steering wander and twitchy steering, not a good thing at higher speeds. Our kits are completely TIG welded and come with all hardware needed for mounting. Just like our traction bar kits, you can also choose colors for these kits.

*Please note that all kits are custom ordered and built and have a variable wait time.
