Is the ARB Twin Onboard Air the best solution? (1 Viewer)

[BadReligion]

How long we talking on these underhood ARB’s lasting? I’m 30k miles and on my 3rd year with mine. If I get 5 years I’m happy, the convenience is worth trading some longevity.

My first ARB twin lost a compressor (mounted under the hood of my 80) at the 2 year mark. Sent it to ARB and they sent me back a new unit that is now going on 10 years of airing up 37s. I'm usually the first done airing up, even from 5psi so I then help whoever is next to me so it gets a lot of use.

In the other landcruisers I use a Viar 440 and it works OK up to 34" tires. Morflate hose to air up and you can hang out inside with the AC on without moving from wheel to wheel every few minutes. Still quick to air up to like 35psi, but takes a bit to get to 50, which is only an issue if we are using the 200 to tow.

I pull valve stems to air down. 1 min per tire.

Curious to try that 18v Milwaukee.

Yeah, I was baffled at how fast it was and even moreso by how quiet and cheap it was.

Originally just bought it as a backup for the ARB. But now i use it exclusively and the ARB is the backup.

Set it and forget it

I do the octopus morflate as well and it’s nice when it’s summer temps in Utah.

Thanks for the info? Sounds like this is just totally random on failures.

Seems so.

Another thing to pay attention to and modify is their odd round screw on air filters (for lack of better term).

They clog with dust and crap FAST. I got in habit of cleaning them when changing truck oil, as part of my maintenance routine.

Then i got tired of it and just rerouted them to the airbox, like you would a diff breather

I should read manuals more often.

Thanks!

Nice mod. I'll take this as a reminder to clean my filter, which I haven't done in a few years.

I have a morflate rubber mounted next to the power steering Resi.

It’s been in there for a few years now. We had our third child about 7 months ago so wheeling frequency is down. But all last year and the year before we were using the compressor 2-4 times every/every other weekend with their 4tire hose. And that’s all year round here in CO.

It has never skipped a beat. For the price expectation is 3-4 years of usage before failure/problems. I think I got it all on sale for BF for like $350 hose included.

The problem is their rubber hoses dry out quickly in the engine bay. I swapped to braided stainless and it seems to be sustaining the heat fine.

For yall looking at the morflate hose thing, they can do custom builds if you need to air up trailer tires along with your cruiser. They did one for me that allows me to air up all 6 tires.

Good idea.

Next time I hear of one grenading, I’m going to try to get my hands on it to take it apart and see why.

I’m GUESSING it’s the filters got clogged up and it overheated

 

[TeCKis300]

I like the idea of an octopus but I don't like the space it takes or trying to keep it untangled. The biggest advantage for large tires is how it improves flow.

Here's my compromise. Not much more space than a standard single hose. But it has a short T-junction where the other tire would be. Also allows me to manage different pressures on each axle when I tow.

The MORRFlate TenSix is the same as the Thor's Lightning True Dual which I picked up on sale on Prime Day for $149 ($199 on Amazon now).

The MORRFlate TenSix Pro is the same as the Thor's Lightning Portable Total Control 12V True Dual

MORRFlate's version now comes with a braided hose outlet QD while the Thor's is a rubber QD

Thor's has a 5yr warranty vs MORRFlates 3 year.

There are a a few other's that rebrand this compressor and put their own small touches on it. EZ Flate M.O.A.B. is another one.

 

[grinchy]

i find the arb twin pretty great. no issues here after 6 years.
combined with the apex valves it is fast up and down.

was basically the only option back then. now id probably get the milwaukee portable.

would still recommend the apex valves. those greatly reduce friction to airing up and especially down.

Damn. I was asking this very question about mounting my Thor's Lightning True Dual in the engine bay and no one had any experience mounting one but the consensus by a few was it wasn't a good idea. If you have have had success with it being there for a few years minus changing out the outlet hose to braided stainless, that's an easy fix.

I have the ARB under the hood, and I love it. We wheel 10-20 times per year, so it gets plenty of use. Besides the speed and reliability, the other thing I like over the cheaper options is it only gives air when you are calling for air. You can use one of these things, set the PSI you want and walk away. When you come back, the tires are exactly as you want them. With the cheaper pump I used to use, once this thing stopped filling the tires, the pump would burst the lines because it had no pressure switch. https://www.amazon.com/Rapidair-Automatic-Inflator-Pressure-Digital/dp/B09PLNC4MH

They are big compressors. They take up too much space in the trunk or in a drawer. I run a single drawer in the back and prefer having it out of the storage area inside.

I run a PUMA which costs less than half of the ARB and will do four 35x12.5x17's from 16 to 35psi in about 10 minutes (100% duty cycle). This compressor has been around forever and has many followers in the 80 section. Mine has been in service ~8 years with no hiccups. I've removed the tank since I don't run air tools off of it and hard-mounted it under the hood. I helped my stepdad install the ARB twin in his 4runner and its definitely a nice unit too, and everybody makes a mount for it, so there is less custom guesswork in mounting it up.

ARB compressor is good, but here are at least a couple comparable (or superior) options for around half the price. These things matter to a cheap-ass like me.

^^^^ This you can't beat the PUMA for price and speed

 

[Broski]

Here's my PUMA not taking up space, with a high flow chuck fills a 39 from 10psi to 25 psi in one minuty 40 seconds

 

[linuxgod]

I don't like the idea of extra Octopus as well but here's the thing, the standard valve stem is the bottleneck with a high flow air compressor.

I disagree. An ARB dual or my superflo dual will inflate a single tire from 18 to 38 psi in about 3 minutes. But a friend of mine had a pressurized tank and I was able to inflate the same in about 30 seconds. Now, could I have done all 4 tires in 30 seconds? Maybe. If that’s the case then yes the stem would be the limiting factor. But I don’t think it is for any compressor without a pressurized tank

Were the pressures the same? That would make a huge difference.
