Today I learned it will fit under the rear seat of an extended cab F*rd if it’s on its side. Sooo does have that going for it 😂. Need the 1 ton to haul it around.

Hooked up my NAPA compressor today, I couldn't be more impressed with this thing! 😍

Love that it comes with a quality rubber air hose, a inline gauge (it doesn't seem accurate though, off/low by 3-4 PSI) and a pressure relief valve. For the price, you're getting a LOT.

Once connected and powered up, the compressor aired up my 39" BFG KM3 from 10 PSI to 35 PSI in 2.5 minutes. For a 39" tire, it looks like 10 PSI per minute. Based on that, airing up 4 39's from 10 to 35 should then take right around 10 min.... well under the 15 min duty cycle.

For the Gladiator owners, the compressor fits perfectly under the rear seat in the storage compartment! I had been running a 10# CO2 tank, it'll be nice to ditch the tank with this compressor.

I'm thinking about picking up one or two more of these for other vehicles... they're so valuable to have!

I used mine yesterday to air up. Comparing it to my single ARB twin, isn't really fair at all. 2.5 tires to the NAPA, 1.5 tires to the ARB single
Mine smokes my Viair 400. I didn't get out the stopwatch but it's at least three times as fast, probably faster.

It's just MASSIVE compared to the ARB dual. Hopefully I can get the ARB twin put back together and operating. It's perfect for my JT which has no interior space once you get some recovery equipment and such in there.

Based on the advertised cfm rating, if you do the modification for larger hose you might be able to speed up that total time by filling 2 or more tires at once. Good real world feedback. I'm sure I'll be happy with mine, as I'll mostly only use it to maintain tire pressure. I don't usually air up and down. But then, I never had a compressor either. 🤷‍♂️

@Maverick does all 4 of his at the same time. I've been thinking of doing two at once but don't want to have all the hoses for a 4 tire setup

I've been back and forth on this. I'm currently not convinced that it'll save much time or hassle. Extra hoses, extra tangle, extra time getting it out and packing it up, extra space taken up by more hoses, etc... I dunno. I'm still thinking about it but I'm worried that I'm being seduced by the coolness factor.

I'm strongly considering mounting a retractable hose reel in back instead. That would be freakin' cool.

I was able to do a quick test of my new napa compressor, on my 01 f250 7.3l on the front tire sized 35x12.5r17, I deflated the pressure to 10 psi, and then hooked up the compressor turned it on and it was able to inflate the tire to 50 psi in 2 minutes 2 seconds. I like the nice long hose that it comes with but will be upgrading the power wires as the ones that come with it got a bit warm while using. It is a bit large for a tire compressor but it is well worth the size for the performance.

side note, when I was talking to a buddy at work he was telling me how great is compressor was, he said it was a thor compressor... he paid around $200 for it and has had it for a couple years. https://thorslightningairsystems.com/products/thors-lightning-bolt-true-dual-air-compressor


they have a wide variety of mounts for their air compressor, see them here https://thorslightningairsystems.com/collections/refuge-compressor-mounts

looks to be the same design as the napa.

Rotbox needs to pick one of these up!
