Description

When lifting the front of the Super Duty 3 3.5, the factory caster is reduced by approximately 1.5. For the 2020-23 Super Duty, we provide a 2 caster shim which is enough to restore this caster and add a touch more unfortunately, this touch more is rarely enough for proper tracking. This leaves us recommending our Adjustable Radius Arms proven to add an additional 2.5 of caster (when maxed). Combining the Carli Arms and 2 shims results in a Super Duty on 37 tires that holds a lane, and returns to center after a turn, better than a stock truck.
