I have a 2004 F150 with stage one ProComp lift. I have been wanting to raise the front enough to run 37 or 38 tires. My alignment guy tells me that my truck already has both A-arms in as close to center of truck as possible. He gave me three choices:
1) Grind the slots out farther toward inside of truck.
2) Find some type of cams to install on top A-arms. (to move them out)
3) Find longer A-arms for the top.

If you can help, I would defenitly appreicate it.

Thank you,
Chad
