Another top-notch PMF product.
These work fantastic for getting you castor back after leveling your super duty. The don't hang way down like drop brackets, and are incredibly well built. And best of all, combined with 2.3 degree caster cams they can get you in the range of 4-5 degrees of positive castor. They also recenter your front axle in the wheel well (front to back).
As Trevor notes, the hardest part is removing the 14 oem frame rivets. After that, install is a breeze.
