The BEST Off-Road Air Compressor!! - Napa "Maxi Trac" Compressor 

Very cool to have, especially if in the middle of nowhere. I keep a tire repair kit & will definitely be getting this...& try to mod it like u.. Thanks for sharing 👍!

I added the 90/125 pressure cut off switch and US quick connects, and a single hose to fill tires. Yes, I could do the 4 tire air up, but for $100 i was able to buy all the parts for the pressure switch, hose and air gun to air up and air down, the 4 tire system that i was looking at cost $160, that was just the hose hook up, i can walk around and do all 4. Plus i added a quick connect wiring harness that hooks into my winch harness so that i don't have to hook on to the battery.

Just now bought the above compressor at Napa here in Prescott, AZ. I like what I see so far. But I examined the tapped compressor connection on the aluminum coupling tube and found it to be 27 threads per inch.....conveniently the same as 1/8 NPT so I ran an 1/8 NPT tap into it and provided the proper angular tap ( it was a straight tap before). Then I applied a bit of blue loctite on the threads of the 1/8 MNPT to 1/4 MNPT adapter and was able to tighten it with a crescent wrench and not hack the black plastic hole in the least. If the aluminum coupler is drilled and tapped for a 1/4 NPT from the getgo then there will not be enough meat to get a hold of on the universal air output coupler. With the new coupler on the compressor now my air hose that I have been using for years will now fit on this new Napa 10.6 CFM awesome compressor. I am now throwing out that POS Napa hose with dial readout in the trash. FYI

I have the All Top variant of this compressor...same thing, different name and probably manufactured in the same factory. I removed the hose and drilled/tapped for a 1/4 NPT connection, added a 2" long pipe nipple and a tee with 2 quick connect fittings. Also got rid of the circuit board and replaced with a 200A relay for more reliability. Replaced the power leads with #4AWG wire and an Anderson connector, which I connect to a mating connector mounted on the front push bar...never need to open the hood. So I guess the warranty is shot. 😀 I may give the HF case a try...looks nice and tidy.

Brandon, thanks for posting this vid on the Napa compressor. You could help a lot of us with a "how to modify" the compressor like you did. I'm guessing the pressure relief valve is the key to preventing failure long term? I'm wondering if an in-line manual bleed valve would be a work around too? Thanks

I bought the same compressor from Napa based on the all the review from Jeep people. I'm betting that all the dual piston compressors that you see on Amazon are coming from the same manufacture, they all look the same other then paint. I have not done the pressure switch update yet but will soon, we used this a few weeks ago while running Hot Springs Offroad park, did great on our 35" on our Jeeps. Well worth the money.

Dude, ok short story. I was looking for a case or tote this past weekend for the wife's sunglasses, she just leaves em around and they scratch or break and I buy her nice ones so fk that! I looked into getting her the Yeti day traveler so she could keep some in there but that case is ass and it's 80$ so I came across good ol Harbor Freight! I was thinking on going this weekend to check out the three cases I saw online but you sir once again sold me in something! I was planning on buying the mid size 30$ in black so thanks man, and ohh yeah the compressor is pretty gnarly for it's size and is without exaggeration faster than the air machine at my local Shell station!

Do you have any video showing the modifications done to the air compressor? And thank you by the way!

Quick question do you wait until the compressor to cool down before you put it back into the HF box will it melt the foam if you store it immediately after use

What size HF/Apache case did you use? Great idea

I have the same size tires on my Tacoma and it takes me about 40 to 42 seconds per tire to go from 15 psi to 33 psi with the engine running. The only mod I did was to change the shader screw tip end to a quick connect, every thing else is the same as it came out the box. Do you think all the mods like the pressure switch are having an effect on the difference in times? I’m thinking about adding the pressure switch but not if it will slow it down. Or maybe the difference was because your test run was with out the engine running ?

Sorry if I missed but did you say you replaced the cords + alligator clips? If so, what did you replace it with?

I love the build. I wonder if the original hose connection to the aluminum manifold/bar was designed to avoid the connection being snapped off accidentally. Once you tapped it with the larger connector do you worry that pulling on the hose could snap or pull out the new connector?

Where did you get the rear wiper delete kit for the xb?

Picking mine up today. What size drill bit and tap for the fitting? And is it a 90-120 pressure switch?

Did you have to Shelli there can you please let me know if you had to solder the cables to make it work

How did you do the hood on your commander like you did?

I just bought 2. Tried using one yesterday. Not sure if I like it. 1.) The gauge doesn't work, reads 70psi most of the time. 2.) This will kill your battery quickly. Keep vehicle running.

What’s the duty cycle on this compressor? Also those pressure switches are notoriously cheap and fail. You should also add a mechanical relief valve rated slightly higher than the switch 15-20 psi or so higher.

Harbor Freight just released a new Maddox 12V Heavy Duty Air Compressor that is compatible to the Smittybilt model. Tons better than the old Pittsburgh model.

I really don’t understand what you meant by “pull the alligator clips under the manifold to make it fit” I’m staring at mine with the cover off and it looks like the only way to make mine fit is to take the manifold + heads, remove them, and switch sides so the 1/8” hole is now next to the board in the open area. Is that what you did?

Add a tank and you’ve got a great set-up 👍

Wow that’s actually pretty fast especially for the price.

I dont get it, how does the air compressor supposedly damage itself

I can't tell if the engine was running when you tested this. This thing draws too many amps to run with engine off. I'm just sorry you didn't record toe actual process of drilling and tapping.

First!!
