Jarmstro, I would not complain about the replacing of the lower control or "A" arms. I had this done and the replacement ones are much heavier duty version than the ones that where replaced (which I assume where standard F150 control arms). At least this is what I was told by my Service writer who appears to be a sharp guy who compared the parts. Any replacement should include a four wheel alignment to Lightning specs.

The replacement was specified by the SVT tech rep.

 

Any Updates?
