I have the timbrens also, they are IMO the best bang for the buck, install them and forget about it. You have the benefit of factory ride quality when your empty. Look under the vehicle and you wouldn't know they weren't factory.
Anyways, If I recall, they make timbrens that accomodate an after-market lift as well.
