ARB Compact On-Board Air Compressor Kit - CKSA12

universal fit logo



At less than half the weight of other compressor kits, this system is ideal for competition vehicles, rock crawlers, or any other vehicle where a compact, light weight, and quick installing design is needed! The compressor features fully sealed components, pressure switch controlled air manifold system, hard anodized cylinder bore with carbon fiber piston rings, relocatable air filter assembly, ball bearing equipped rotating components, and the low current draw of 5 amps at no load and 6.5 amps at full load means it will run on the 12 volt accessory supply of most 12 volt and 24 volt vehicles.

If you use your off-road vehicle for competition, extreme rock crawling or other high-caliber adventures, you probably regularly add and decrease tire pressure. You may also have external components that require an air supply. Fortunately, you do not have to drive back home or to a service station when you need an air fill-up. With an ARB compressor kit, you take a steady supply of air with you wherever you decide to go. At 4 Wheel Parts, we have the compressor kits, aftermarket air accessories and other components you need to outfit your favorite off-road machine.

The Correct Tire Pressure for Any Purpose

Off-roading like a pro is a lot about driving skill and tire pressure. If you are trying to maneuver your rig over tough boulders, through shifting sand or across muddy terrain, you must be precise with the amount of air you put in your tires. Naturally, though, surfaces change considerably over the course of any trail ride or competition. Rather than mid-ranging your tire pressure and hoping for the best, carry an onboard compressor with you. Air compressors from 4 Wheel Parts get the job done. The ARB on board air kit is the lightweight solution for your on-demand air needs. This kit comes with a pressure-controlled air manifold system that allows you to air up tires and air accessories for trucks and Jeeps.

The Right Price for Your Off-Road Budget

There are thousands of ways to upgrade any truck, SUV or Jeep. Still, if you are looking for a no-hassle way to enhance your off-road experience, investing in an ARB compact air compressor makes sense. You do not have to pay a premium for the top-quality aftermarket upgrades you need to improve your ride, however. When you order from, you always take full advantage of our low prices, responsive customer service and expansive parts selection. Whether you are looking for a compressor to fill your tires or air accessories to help you conquer extreme trails, we have you covered. Simply use our intuitive search feature to find exactly what you need to customize your machine. Then, complete your order today to give your 4X4 an advantage over the competition.

1.0 China junk!

It’s a piece of junk made in China. It will not last. Parts of it were corroded. This was my second AirLocker air pump. When will America stop making products in Communist China!?

5.0 Worth the money

I put this in a 87 4runner, and the install was easy and the harness made things even easier. Also 4wheelparts took care of me, and got me a spare part that was missing over night.

Q: What is the duty cycle on this unit Answer this question

A: Hello Sabby, ARB does not provide a duty cycle. The did offer this "It's small enough to fit into even the tightest space and quiet enough to mount in the cab. It has enough output to air up four 35" - 37" tires in a single duty cycle and typically airs up a 35" tire in just over two minutes." Thank you.

Q: Will this work for a rock crawler, 44 x 18.5 tires, if I plug a tire? Only run around 8 to 10 pounds in them. Answer this question

A: Hello ExpensiveDream, Provided you are not in a hurry, it will work for you. If you are looking for something faster we suggest a Powertank.

Q: Does the kit come with air lines to run to front and rear locker? Answer this question

A: Hello Sorry for the slow response your question seems have been lost. The air hose come with the locker's not the compressor. Since they don't know if you are running one or two lockers. The hose can be bought as a separate item the part number is ARB170301 it is 5mm by 20 feet long. Thanks
