Are aftermarket upper control arms required on the 2010 - 2014 Ford Raptor systems?
No, aftermarket up control arms are not required on 10-14 Ford Raptor. The Raptor UCA’s provide enough alignment adjustment to set the vehicle within the factory alignment spec range. Lifting the vehicle over 2.125” on some vehicles the stock upper control arms have difficulty getting caster correctly within the factory recommended range. Vehicle set with less than 2.125” of lift can be aligned using the factory upper control arm.
