Few details for ya after a quick read....
-The wheels are forged aluminum units I believe after talking with the hutchinson guys at EJS. Lighter than you would think, but still heavy with the rubber beadlock liner. They are 5.8X" backspacing also. They would be just about perfect for a J8 in my opinion
-The front axle is a pro-rock D44 center with D60 knuckles I think? Perhaps a little lighter than a full D60, but still pretty dang heavy knowing dynatracs historic axle stoutness.
-Can you say full float rear axle WITH the huge J8 brakes....no more c-clips.
I think the concept was spot on, if they offered it it would sell in a heart beat. The vehicle market is screaming for stuff like this...stuff that still has a soul. It might not be perfect with the chopped windshield and top, but it isn't any worse than an H2 or H3 in visibility. Jeep needs to bring back the endless style of a properly done utilitarian vehicle. This and the J8, or even J7 concept, come very close in my opinion. Also, PLEASE, if your reading this Jeep, give us the diesel already. How many times do you need it proved that it will work and can sell in the USA.
