I thought I'd do a little write up on this because in my months of searching I couldn't find a single person that had mounted a twin ARB under the hood of a 3.6 JK and thats really what I wanted. I have a 2 door with the fold & tumble seats and side air bags so under the seat wasnt easy & I really wanted it under the hood.
So I found MORE makes a dual battery tray, we did some modifying to mount the ARB securely:
First things first - let the air out of the front tires!
Next we pulled the old battery tray, fuse box & air intake:
The dual battery tray requires chopping & reusing a part of the old battery tray, so we did that & then a test fit of the tray & ARB before adding the battery:
Everything fit perfect - heres the final install:
I wanted the switch on the A pillar:
It did throw a code & check engine light came on at first start up but we went back & found a wire had not been connected. There was a ton of wiring involved, especially having to remove the fuse box.
I aired up my 35 from 0 to 30 in 2 1/2 minutes. Its quick! It was a pretty long install, I'd say it took 2 very knowledgeable Jeep people probably 8 hours total, but it was well worth it, I'm super stoked & think it looks like it came from the factory there.
