There seems to be a lack of information out there on this carrier so I thought I would add some pictures and info, hopefully this will help someone else out.
First off, I should mention I am running the gen 1 version of the rear ARB bumper, some modifications were required to make this work that would not be necessary if you are using the newer style. I wanted to go with this carrier for a couple reasons, The quality of ARB is very good, I am running alot of ARB hardware already so I wanted to stick with the same theme. The biggest selling point was not having to open the carrier to get in the back of the jeep, it opens as one unit.
A big thank you goes to James Pierce and Justin Tucker for helping with the install!
with the arm resting in the closed position, it does not line up with the bumper. The arm needs to be moved out and in order to work correctly.
We cut, bent, and welded the arm in order to clear the body of the jeep and to mount it in the best possible location.
Here it is mocked up, by making the modifications we shortened the arm which makes the tire set slightly to the right side of the jeep. It actually worked out better that way, there is more room to reach the tailgate handle. This also required a longer turnbuckle that attaches the swing arm to the tail gate.
Bumper reinforcement: Since the carrier was not designed to support the weight of the tire we had to come up with a way to reinforce it..
I molded a piece of metal strap that would line up with the additional plate I bolted under the carrier spindle and the support bar of the bumper
I didnt get a pic when I had the bumper off, but I snapped this the next day. It shows the bracket and support arm welded together. This made a HUGE difference, this thing is really stout now!!
Im not completely done, still need to make a mount for my license plate, hide the wiring, and make some brackets for accessories. Then send it off for powder coating.
