Caster; the steering pivot angle; is tilted either forward (negative) or rearward (positive) from vertical. Installing a suspension lift or leveling kit will cause a reduction in steering caster angle. This can result in wandering; wobble; and general steering instability. Larger tires can exaggerate the problem and require more positive caster. By installing BD's Cam Caster Adjusting kit on the radius control arms of the Ford Super Duty's; you can correct the problem by increasing the caster angle to gain stability.This Part Fits:YearMakeModelSubmodel2011-2022FordF-250 Super DutyKing Ranch2011-2022FordF-250 Super DutyLariat2018-2022FordF-250 Super DutyLimited2013-2022FordF-250 Super DutyPlatinum2011-2022FordF-250 Super DutyXL2011-2022FordF-250 Super DutyXLT2011-2022FordF-350 Super DutyKing Ranch2011-2022FordF-350 Super DutyLariat2018-2022FordF-350 Super DutyLimited2013-2022FordF-350 Super DutyPlatinum2011-2022FordF-350 Super DutyXL2011-2022FordF-350 Super DutyXLT
