Anybody else did that?
It's a good idea, but some policies exclude lifted or modified suspension from even writing a policy, so you could get dropped depending on your carrier.
I almost made that mistake. I mentioned to insurance my sons truck was lifted and they said the vehicle would be dropped by insurance. So I preceded to play dumb dad and say well its not lifted but its a tall truck. lol
I try to talk with insurance as little as possible.
Problem with that is that they may refuse to pay if something major happens and they send out an adjuster to examine your vehicle.
