Stifflers Upper Control Arms - anyone try them on a Gen1?

[Tjhoward84]

Anyone try using Stifflers Adjustable Upper Control Arms on their Gen 1 Expy? The Stifflers website says these are for the 1999-2004 F150 2WD only. My 1999 Expy is 4WD and has been lowered using the Ground Force kit for Expeditions with the 4 corner load leveling suspension. My problem is the driver's side camber won't get into spec and the shop says I need an adjustable upper control arm.

Let me know your thoughts.
