For as long as I have had this G.E. I have wanted onboard air. I finally have gotten around to doing it. Taking the ARB from the Gladiator and using the Mountain Offroad engine mount it went on over the last week. It did take some more work than expected. The mount doesn't play super nice with the cruise control cable, but it does work. I had to cut the brake booster line short to try and get it away from the mount and added in some reinforcement, hopefully it doesn't cut a hole. I'll probably look for another reinforcement option the next couple weeks. I also had to get a new vacuum line for the rear breather/PCV - fortunately mine did not break coming out! Instructions say to use the existing one but it doesnt work in the slightest, at all - not even close since it is a hard plastic line. Maybe for older years but not for the 05-06. So I had to get some 3/4" heater core hose, a 90 degree elbow, and a hose clamp. 3/4 just barely fits on the intake side with a good amount of force, and the hose clamp is needed for the PCV side since it's only 1/2". Also, adding some reinforcement where the hose goes through the hole in the bracket is needed to prevent wearing a hole.
The wiring and hose hook-up is a mess right now but it is functional. Next task will be working on the rear storage compartment, and re-doing my aftermarket wiring that has been a mess for the better part of 7 years.
The booster hose can be bent out of the way some simply by twisting the valve on the booster end more toward the ground. But I'm sure that vibrations will push it back up to this position. This is a temporary 'fix' just to see how much wear happens over the next couple weeks to determine what course of action to take.
Barely visible is the IAC wire. I used the only piece of conduit I have at the moment for protection as the wire rests right up against the edge of the bracket support here. There is not enough room or extra wire to re-route it. Again, a temporary fix so I can check back on it in a few weeks and see if it is rubbing and what course to take.
Here is the almost finished product except wiring and hose routing. This is the compressor from the mobile kit. So I have the 1 gal tank that I wont be using, which is why there is not the hose coming form the top center. I do think I will try and fit a 2 gal via tank under the body since I plan on running airbags. The bracket is tight, very tight. For the 05-06 years, it is not perfect - but there are not a lot of other bolt on options. In fact, I dont know of any bolt on options. I was considering using the new compressors from VIAIR for the LJ, since the LJ does not have cruise control or ABS. But, I do like how this is packaged, and once installed it shouldn't need removal unless there are problems that require accessing the fuel rail or sensors. So I might just opt to get another one of these mounts, and pick up the new ARB brushless compressor - supposedly it is quieter. Overall, I do think this is a decent mount to go with. not perfect, but probably the only real bolt on option out there that I'm aware of anyway. Mounting the compressor prior to placing the bracket on the engine is a must, but that makes accessing the little 10mm bolt under the compressor that bolts the mount to the intake difficult. Test fitting prior is of course a must. One bit of concern I do have is the included bolts that secure the bracket to the head studs. I did not use the included nuts. Instead I got some different style lock-nuts. The nuts they include with the kit are far too tight and my concern is that if having to remove the bracket 3 years from now, those nuts will be so tight you would end up loosening the head stud instead which would really suck bad. I think the future using an old school lock washer with a standard non-locking nut would be the best method. It is functional now finally which is great.
