The new Super Duty radius arms (details below) can be sold as an upgrade for the Ford F250/F350 with 2-4" of front lift. They cannot be used with radius arm drop brackets at these heights. Therefore, if someone has a current BDS radius arm drop bracket kit, they will need to remove the drop bracket to install these arms.
For those with 6" of front lift, the radius arms can be installed with the drop brackets as a direct swap for the factory radius arms - only caution would be that the caster may need to be checked if ball joint cams are installed.
The new arms use the factory mounting hardware at the frame and a combo of factory and provided hardware with cam locks at the axle.
