Kraken Air system, ARB Twin with Pressure Control under passenger seat

[Abend]

Next question: as mentioned above, I may try to plumb in a separate ARB air locker solenoid that would divert air from the main system to my airlift airbags. Those airbags are required to be kept at a minimum of five psi. Do you think this system is leak proof enough to leave my air compressor turned on all the time, the ARB solenoid activated, and does the air pressure system stay live at a preset psi even if I have the app closed? My thought would be to leave the system set at five psi all of the time, and when I needed to air up my tires, I would close the air locker solenoid which would close the airlift airbags system and then I could use the tire system independently. I know this is getting awfully complex, but I’d rather have a system for the airbags where I don’t have to remember to constantly check that 5 pound number to keep them inflated properly. Thanks.

That's all going to depend on the air lines you use, but that's totally doable. I'd just stay far, far away from the push-to-connect style connectors if you're worried about small leaks. They're airtight at first, but as you drive on trails the vibrations will shift things around and they will develop leaks - not enough to matter for airing up tires, but enough that your compressor would probably kick on every couple of minutes.

The ARB app lets you set startup options for the compressor. You can either set it to blast unregulated air when powered on, set it for controlled pressure at a user-specified pressure setting, or you can set it so it's off until you tell it what to do. It's really flexible.

Did you pull the harness though the drainage port or through the firewall? I saw an install video where the harness was pulled through the passenger firewall making it a cleaner install. I think I’m going to go via this route when I install mine.

I ran mine with the suppled wire loom with the compressor up through the drain plug under the seat. Didn’t want to use one near pass feet especially since I have armor lite floor. Harness comes to a perfect place.

Do you think the app is capable of telling it's regulator to hold 5 PSI even when the app is turned off? Or will I need to open the app from time to time to let it fill the bags to 5 psi (if they aren't already there?)

Thank you for all of this info!

Definitely, you would just set it to 5 psi and change the power on mode to control and the control module will automatically keep things at 5psi whenever it has power. The app is only needed when you want to change the pressure.

This is great info! And I hear you on the quick connects. Do you have a suggestion on non-quick connectors? Does ARB sell those? I haven’t looked for any of that yet. Thanks again.

Nothing special, I just plumbed everything with 3/8 hose and hose barb fittings. It's definitely not as convenient to install as the push-to-connect style connectors, but so far it hasn't developed leaks.

I think you'll want a separate regulator for the airbags, the relatively low pressure and smallish volume of airbags will probably cause issues with the pressure control system, I have seen mine overshoot quite a bit at low pressures.

Good to know. I may just do those manually when it’s all said and done.

Passenger side, right under the passenger seat. I was kind of mystified why the instructions didn't tell you to use this hole, because it's perfectly located for the power cable.

I found the round plug you referenced. What size grommet did you use to cover the hole? if you have the brand/dimensions, that would be great. i’m going to use that same opening to run my wires.

I think it was a 1 inch one, but not 100% certain. What I can tell you for sure is that it came out of this kit:

https://www.amazon.com/gp/product/B09Q2R7GML

The hole is oval, but the grommet is flexible and lined it perfectly. I just cut an X pattern in the center and then passed the cable through it after removing the pins from the connector housing.

Looks like it’s going work just perfectly going in through the round 40mm body plug (68145148AA) without taking up my drainage opening - it's a much cleaner install. The cable still has electrical tape so I'm just waiting for the rubber grommets to arrive from Amazon, reassemble the harness connector and it’ll be fully installed. I decided to keep the ARB switch cover because the Octopus pic is a bit too much imho..

Just curious if you guys are trimming the black crossover tube to keep the install neater? There is quite a bit of it and i was thinking of cutting off abt 6 inches.

I can tell you with the armorlite flooring, the kraken and arb pressure control does not work. The push to connect hose and fittings hit under the seat and leak. Looking at threaded connections to try and solve this. Otherwise might have to go under the hood and sell the kraken.

I did cut some off the crossover originally.

Guys: if I want to inflate all four tires to 33 lbs, but then have my rear two go to 35, do I just unhook the front two tires at 33 and leave the back two plugged in? Or does this system just blow air out of each hose all of the time? Is there a closure valve on each hose end of are they “normally closed” until hooked to a tire? I guess the same question would hold true to inflate one tire on a friend’s vehicle. Thanks for the info!
