why would you think a warranty would be cancelled for putting on shocks??
Also would you really want to use a shop that looks at your vehicle and tries to deny a warranty claim on say the transmission because you
have better than factory shocks?? If you had an 8" lift kit with 37s... then yeah they might have a case for denial.

 

I believe he is referring to the 3 year warranty through Ford if a Ford dealer or ASE certified mechanic installs the shocks and struts.

 

Check the link I posted in the first post. It explains the warranty,
I don't want Ford to say **** to me about anything if I have a front-end problem. Manufactures look for anything to deny a warranty claim, then it's up to you to prove what you did wasn't the cause of the problem.
