My father just got a Super Crew and I convinced him to lift it up. He agreed but wants to know if a spindle lift and rear blocks will affect his warranty. Anyone have any solid information about this? Also i have the spindle lift on my f 150....and was wondering if the aim or fabtech spindles will work on the supercrew?

Thanks in advance......

 

Hey man, i was wondering the same thing. I need to lift my new f150 but dont know if it will void my warranty.

 

Also does a new intake system void the warranty??
