We have 4-door aluminum sliders on our JK 4-door and are extremely resilient (sp?) against rock abuse and misuse. We have drug and hung off of them and are OK to this day.
On a side note, we can get the 4-door model and drop ship them to you. We are contemplating becoming a yellow star member over here also. But, we are a yellow star over at PBB and you can order anything you want through us.
Call me at 541-273-5337 for any questions. Name is Wally.
