Hi BiggSean - congrats on the new truck!

Question #1 - I didn't know the 2011 Expys had HID headlights! Wow - do I need to go hunting for part numbers to replace my conventional headlights?!

Question #2 - if your King has air suspension it's my understanding you can't "lift" it. There were a few posts a month or so ago where some of the guys were discussing this topic and chatting about which kit was best. Do a search on it.. Don't know about the warranty issue - doesn't Ford typically use any excuse not to honor a warranty claim....

Question #3 - Tire size won't matter. TPSs are only looking for tire pressure. 35 PSI in a 33" or 35" is the same.

Hope I helped a little. Enjoy that new truck!

B/R,
Randy
