Brah, if u choose to go you'll have a blast. In Hawaii no law on suspension, you can have suspension/body lifts. The key is frame & bumper height. Truck's frame can't be higher than bumper. The body can't be higher than 3 inches above frame. There's tons of lifted rigs on the islands, it's part of our culture some what, many times cops enjoy them and see no violation if u know what I mean. U play it cool and then da cops play it cool too.
Hey also check out LIFTLAWS.COM and look up Hawaii, it might clear it up much better for u. ALOHA my friend and thanx for your service.
