That's a bummer. And I see you're getting no shortage of feedback here which may or may not be helpful (including my own, lol).
I had all my work (Eibach level, Method wheels, Corsa, K&N and the Predator) done at a dealer.
I am fully aware that in the event of catastrophic failure, I may be SOL when it comes to warranty work.
That said, the work done all falls more or less within factory tolerances, and for any minor grievances I've had including a suspension 'clunk' that's shown up since the level kit and some vibrating with the intake, the dealership has been pretty cool looking after this as part of the maintenance plan on the truck or for a half hour of shop time.
Is your local dealer cool enough to help here?
