Re: Shock Length
I know that the piston will not sit where it is suppose to normally be. It may increase wear on the shock, in theory.
Have you asked the people at IRO? Having been to the shop a few times, they have good knowledge. They may be able to recommend or give the thumbs up to the 4" shock on the 3" lift.
