Does anyone know of any strengthening thats available for 2012 JKU rear door. Looking to stop the flexing caused by the spare tire mount, without changing the mount itself or the rear bumper.

 

No tailgate support that I am Aware of.. Are you running the factory spare or a bigger tire? If a bigger tire I suggest a new rear bumper with swing out spare tire carrier.. I have run smaller 35" tires on the factory carrier without issue but the tire actually sat right on the factory bumper...
