Overall a good product but the mounting system needs to be better thought out. I purchased this to replace a QuickAir 1 compressor mounted in the engine bay. The two are roughly the same size with the ARB being slightly taller. I have yet to hook this up to my existing 2.5 gallon on-board air tank and try airing my 35 tires back up so I cant speak for ARBs claims that this compressor is significantly better than their original smaller compressor in that respect. The silver tube at the top of the compressor is an air reservoir which is there solely to have a small reserve for actuating ARBs air locker(s). There are three ports. The tube is designed to have both locker solenoids installed on one side and the pressure shutoff switch installed on the opposite side (opposing one of the solenoids). The silver tube can be rotated to some extent to point the ports at a different angle and the silver tube can be rotated to position the solenoids on the opposite side of what is shown in the illustration. Theres quite a bit of flexibility for positioning the solenoids. Since I was replacing an existing compressor and didnt want to re-engineer the entire setup, I installed both solenoids on the silver tube vertically (air vent pointing up). Note: I run vent tubes from the solenoids to exhaust outside the engine bay under the chassis in a protected location. Passengers have complained about occasional exhausted fumes from the differential(s) drifting back into the cab if the window(s) are down. The issue is that there isnt enough clearance between the two solenoids when positioned parallel to the silver tube for the fittings on the solenoid vents to fit so I positioned the solenoids vertically. This significantly increases the height (or width if the compressor is rotated 90 degrees in the mount). If the compressor is mounted on a bracket on top of a fender well as mine is this may cause hood clearance issues. Fortunately, I had just enough space to clear the solenoids. The compressor itself can be rotated either way 90 degrees from the mount base plate and at any degree in between. Also a nice touch. That gives a lot of flexibility in mounting locations. The single negative point Ive run across to date is the mount bracket (base plate) and as far as Im concerned theres no reason for it. This is a simple problem and should have been considered by the engineer(s). Not a big surprise to me as this isnt the first ARB product where the engineering has fallen down on a simple, basic point while acing all the complicated issues. In order to mount this compressor, you must have clearance to the bolts that mount the black steel plate from the sides or bottom OR clearance from both ends to the bolts that mount the compressor heat sink to the black steel mount plate. The blue band is an aluminum heat sink that wraps around the compressor motor and attaches the motor to the base plate. The band/motor is attached to the black base plate by four Allen head screws - two from each end running parallel to the motor. Unfortunately the body is larger in diameter than the black steel base plate so its not possible to get a socket onto the bolts from the top. That means you must use the supplied carriage bolts and a boxed/open end wrench on the nuts from the side or a socket from the bottom. Presumably, the idea is to remove the motor/heat sink from the black steel base plate, attach the base plate to the body/fender/stand/etc., then re-attach the motor/heat sink to the mount plate via the four screws. Thats great as long as you have at least 6-8 of clearance AT BOTH ENDS or to EACH SIDE. The four screws run through rubber bushings which makes re-installing them very close to impossible using just finger tips. At the end of the day it took 6 hours to install the four screws and two of the carriage bolts (one one one side at one end, and one on the opposite side at the other end). It proved impossible to install the other two carriage bolts without drilling 3/4 holes through the fender and fender skirt. Obviously no thought was put into actually mounting this in real life where there wasnt a foot of clearance all the way around the compressor. The solution is simple. #1 Make the blue heat sink band a two piece clam shell unit. Half the job is already done. The band has two screws that loosen to allow the compressor to be rotated 90 degrees. Put two on the other side creating a clam shell setup. Take the four screws out, lift out the compressor, bolt everything up and put the compressor and four screws back in. #2 Make the black steel mount plate a two piece unit. From ARBs illustrations, it appears at first glance to be that way already. Its not. Make it a two piece unit so that each end of the bracket can be flipped 180 degrees so that the tabs point towards the ends of the compressor vs. the center. This would allow for using a small 1/4 socket wrench with a long extension to bolt the compressor to the body/fender/whatever and not require removing the compressor/heat sink assembly from the mount plate. The compressor comes with wiring and a bag full of hardware. Since I already had a compressor (rated at a higher amp draw) with dual air locker solenoids installed almost all of it turned into misc spare parts. One piece that I REALLY wish they would have put in the bag is the T that they supply in one of their other kits. The T screws into the port used for the on/off pressure switch and allows for the pressure switch to be installed and still have an open port to attach an air line for an air tank. Or, again a simple solution, would have been to have four ports on the silver tube. Overall the product seems to be decently built and I expect it to do what its supposed to do for some time. Were I doing this on a new vehicle without a previously installed air system, I probably wouldnt have gone with a compressor at all and used a QuickAir CO2 system to actuate the air lockers - or maybe I would have gone with mechanical lockers instead of ARB air lockers.

Absolutely love this compressor, I mounted under my seat to avoid the heat of the engine to hopefully prolong its life.

This product set was a little bit pricey, but ended up getting it and I am glad I did. It was not too difficult of an install at all. Product seems like great quality as well as the parts. The actual compressor was a bit heavy in hands, but fit under hood perfectly. I love the convenience of the product as well as the time it takes to inflate my tires.

Bought specifically to run the air lockers on my jeep. works perfect. no leaks. no issues. easy to wire up.

It is nice to have on-board air, it is better when it is quick! Everything you need is included, except a mounting bracket. You will have to find one specific to the vehicle, have one made, or fab it yourself. I use this often, a few times a month. I typically air down to a little under 20 psi on 265/70/17 BFG ATs. It takes me just under 10~ minutes to stop, prep, and fill my tires back to 38 psi. Note: my truck is less than a year old, I still have my stock battery, I have to leave the engine running. It would fair far better with a larger capacity battery installed.

This compressor is great, and I would expect nothing less from a company like ARB. I mounted it under the hood of my 2006 Jeep Wrangler TJ, and use it strictly for airing back up after a day on the trails. Will air up all 4 tires from 15psi to 35psi in about 10 minutes. Not bad considering the space and cost of this unit. Will also run air lockers if you choose to go that route. Not much else to say, it is just a compressor. The harness that came with the unit is great, really made for a simple and easy install. Switch fit into the stock TJ blank switch spots with slight modifications (nothing a small file couldnt fix). Worth the money by far. The only gripe I have about it, is that I didnt install it sooner :)

Been using it about 16 months now and it has begun to squeal like a pig, I am talking with ARB USA now. Lets see how this turns out Update #1 They are requesting that I ship it to them (at my expense) Will let you know what that cost? Update #2 Finally got around to sending it back , $18.75 to ship it via USPS Flat Rate Large box. Sent it on the May 17th. , they got it on the May 19th. Update #3 I just heard from them yesterday. even though they couldnt replicate the problem (Screeching when cold) , they are replacing the unit with a new one anyway (+1 for customer service) Update 4. The new one doesnt t like the cold either, but out of warranty now.

Installed under the passenger seat in my Jeep JL. Works great for quickly airing up tires but won’t run air tools without a tank

Super heavy duty compressor. The harness that is included makes install a breeze. No overheating issues as of yet. Fills tires in seconds. The fact you can add a tank and use it for pneumatic tools is awesome.

This compressor is highly thought of, but I found several issues that I would not expect in a high end product: 1) The housing at the outlet port appears to be made of cast aluminium, and cracked causing a huge air leak. 2) The steel shroud protecting the outlet side of the compressor unnecessarily interferes with the installation of a fitting to the outlet port. 3) The electrical connectors connecting the wire loom to the compressor are difficult to lock. On the positive side, this compressor fits into small spaces, and is pretty easy to install. I am exchanging the compressor for a replacement, and will update this review if necessary after I receive the replacement. UPDATE, FEBRUARY 8, 2018: I have received and installed the replacement compressor. Sexton accepted the faulty compressor back with no hassle whatsoever. Given the good response, I have upgraded my overall rating from 3 to 4 stars, For those thinking about running any sort of air tools from this compressor, you will definitely need an air tank. Dont count on more than a 20% to 40% duty cycle as this compressor cant keep up with any more. This is not a fault, this compressor does everything that it was designed to do. It is fine for inflating tires, air mattresses, etc. I am able to run a pneumatic impact wrench in short bursts to remove lug nuts with the addition of a small (500 ml) air tank. Overall, I would buy this compressor again.
