Onboard GX470 Compressor for ARB Locker? Possible?

[Riflman]

I still have my airbags in the back, and when they fail, I'll likely switch to coils, with airlift bag auxiliary bags inside and hope my compressor doesn't quit.

I am planning to install an ARB air locker in the back and am wondering if it's possible to tie into my Lexus air compressor with a switch of some sort in order t activate my air locker? Long shot, but if possible it could save me $275 for a dedicated compressor.

Short version, it's too small to be useful.

No. I have ARBs and it doesn't make enough pressure

Interesting, the factory doesn't make at least 85 psi to activate lockers. Do you know if the built in pressure switch is stopping the oem air comp from achieving higher pressure? I assume there is a built in press sw of some kind.

I wouldn't want to waste my time and energy on the stock compressor when there are some excellent and inexpensive 100% duty cycle compressors out there that give you a lot more capability. I have been drooling over the Puma setups I have seen, but have also been thinking about going the DIY route with a Viair compressor under the hood and mounting a tank somewhere on the frame rail.

Not bothering to search for the best deal, here is what I found without trouble.

First, a ready-made bracket to mount your compressor on.

Next, a constant duty kit with everything else you will need. This one can even run an impact if you felt the urge.

If you are trying to do this super cheap, and don't mind losing your air conditioner, just convert that compressor and grab a tank. Pretty sure there is a write-up somewhere on here that explains how to do it.

That's a Viair 450c with a flow of .97 cfm @ 90 psi. 22 amps. From here VIAIR Corporation - 450C Compressor (P/N 45040)
Puma PD 1006 with a flow of 1.37 cfm @ 90 psi. 46 amps. From here http://www.aircompressorsdirect.com/manuals/pumadcspecsheet_2.pdf

The Puma has better specs but not sure if you can separate the tank and fit it in your vehicle.

Okay guys. No worries. I had a 15# powertank kit that I sold a couple of years ago when I finally ditched my Disco II. I might just go with the smallest ARB unit for lockers only and either carry a decent 12v or get another 10# tank rig. With some basic research I don't think it's worth it to spend the money on the midrange ARB compressor just to do a half ass job on tires. It takes up more room during install, and that extra $100+ can go to a tank or high volume 12v pump.

You can't go wrong with the tried and true MV-50 red air comps that garnered a lot of positive feedback in the Mud board. I've helped few guys install a pair of them in their rigs over the years and they're still performing well. You can't beat the bang for the buck factor when it comes to these air comps. There are even thread on how to port the heads and all that nerdy mods!!! Space being premium, I'd have a permanently mounted OBA that does everything, IMHO.

Interesting. I'm just learning about the options for compressors. I installed two TrueTracs in my last rover along with gears because I was worried about air lines freezing (I lived in one of the coldest parts of Canada and am actually going back early next year) and so chose LSD's instead. Cost was also an issue since I also just spent $11,000 putting in a new LR motor. I had 34" super swampers on the truck and those truetracs were almost useless. I would have been better with CDL and one rear ARB. So this time I'm going ARB. Not going to bother regearing either.

I was just watching videos on the MV90 yesterday and it actually ran the same time to air up from flat as the mid ARB CKMA12. The MV90 is twice as big as the ARD though and according to the videos below, is almost the same price.

Part 1:
Part 2:

I'll do some more research on the MV50. I haven't even got that far, but I'm guessing it's available as a kit with all the wire looms and switches as well? Is it as durable and water resistant as the ARB?

That's a good vid, I wasn't aware of the mighty MV-90 air comps being so powerful. The MV-50 comes with none of the items you mentioned but they're easy enough to put together. Just do a search on Amazon and you'll see what they come with.

On a side note, when I had a RRC, I build a high torque 4.6 to with a nice LT-230 box. This was back in the day, before the 80 came to my life. Lots of good and not so good memories with that RRC!
