Our JKUHR arrived in 4 weeks from order - If the dealer attached a name to existing allocation it moves to the front of the line.

We ran the AEV 2.5 with 35s - my only complaint is that the 2.5 can NOT handle the weight of gear and a RTT. We did cram a lot into a two door ( m(a)ce can confirm that ) but the rear sag was extreme. Our JKU build will run 3.5 with 35s.
