There you go... short of moving, you have three choices. You can either make the mod pass existing law somehow, (like your fender flares), fight to change the law, or hope-you-don't-get-caught-pay-to-play.
What's the purpose of going higher than 6' and 37's for an on-road truck? Does the body lift really serve a purpose or just appearances? If it was TRULY an off-road capability question, the bumper height wouldn't be an issue because the truck would be a purpose-built off-roader rather than a jack-of-all trades-master-of-none.
I'd either quit lifting while i was still legal, or lower the bumpers after the lift (likely destroying the look of the lift).
