ARB CKSA12 12V DC Compact On-Board Air Compressor for ARB Air Lockers & Locking Differentials - Perfect for Off-Road Vehicles, 4x4 Trucks & Jeep Adventures

The compressor arrived super quick, but the toggle switch was damaged in transport. I contacted the seller who was VERY quick to respond, and continued to respond quickly during all of our correspondence.They were very courteous and contacted thedistributor on my behalf and had a new switch to me NEXT DAY. I was relieved that I didn’t have to deal with weeks of an exchange process and was able to finish up the compressor installation.The compressor, and all related components are very high quality. Installation was a breeze, and the harness leading from the battery to the compressor, and from the compressor to the cab was the perfect length. The amount of lead provided into the cab is sufficient enough to allow for switch installation anywhere a driver could reach.The bracket used is the EVO 1097 compressor mount.A must have for any ARB pump. Super easy to use with plug and go setup.I’ve had to replace my Jeep’s air line hose & finally got ARB. Wished I’d had this hose originally. Wouldn’t have spilt has my prior hose did. The ARB hose is very durable.I installed this compressor on my last 3 jeeps to operate my Yukon air lockersWorks as advertisedI purchased this compressor to mount under the hood of my Chevy Colorado. I ordered the compressor and was surprised to have it the next day. I had used the free shipping that stated 5-8 days. I was very surprised. I opened the box to find the compressor and parts to be in excellent condition. The box contained everything needed for installation. It even had ring terminals and connectors to wire the harness to the battery. I was very happy with the wiring harness as well. The harness that is supplied with the compressor is designed for lockers, but I am using this compressor for tire fills. The harness was labeled very well and instructions were clear. I had no trouble with the wiring harness. The harness is plug and play. ARB even leaves one plug disconnected so only a small hole has to be drilled to get the switch to the cab area. I simply taped off the wires that I was not using. The wiring had a nice looking switch that is designed to be recessed in a small cut out. I found the switch to be good. The location I mounted the compressor was very tight, but the mount is made to pivot. I was unaware that the compressor body and manifold tube can also be rotated to facilitate various mounting locations. The compressor itself was heavier that I expected, but that was great. The compressor feels well made. I mounted the compressor and made the appropriate wiring connections under the hood. I actually mounted the switch under the hood as well. I used a small plastic gang box used in home wiring and used a Dremel Tool to route out a hole for the switch. I then used a metal plate to cover the box.I was then ready to use the compressor for the first time. I hit the switch and the compressor fired right up. The compressor only ran for about two seconds and shut down. The compressor comes with a pressure switch that shuts down the unit at around 90-100psi. The manifold tube is very small and it gets to that pressure very quick. The manifold tube also has a built in pressure safety relief valve just in case the pressure switch fails. I am not sure what pressure is required to permit the safety valve to operate.I had to source my own fittings to use the compressor as a tire fill unit. I did not purchase the kit offered by ARB because I can build it cheaper myself. I spent an additional $15.00 to make a manifold for my tire fill kit. I had to buy several pieces due to my mounting location under the hood. I also suggest to anyone that purchases the ARB tire fill kit to buy some Teflon tape. I completed the procedure and was ready to fill a tire. It should be noted that I already had 50 feet of 3/8 air hose and fitting to use the compressor. I wanted enough hose to reach from the engine bay to the tires on my travel trailer without uncoupling the trailer.I had been carrying a portable air tank in my truck that holds 120 psi. I decided to test the compressor by filling it up. I turned on the switch and watched the hose fill with air. The compressor then promptly shut off as designed. I filled my air tank from approx 40 psi to 90psi in approx 1 1/2 to 2 minutes. The compressor stopped filling at 90 psi. I was still impressed at the speed given the size of the compressor. I filled a car tire from 10 psi to 32 psi the next day and was equally impressed at the compressor. I think it was a wise investment and would buy it again if I had to go back.My installation took my friend and I two hours to complete. I had a small area to work with and had to "build" some tools to install some small screws in a tight place. I think my installation time was long, but I had a unique mounting location. Anyone with basic skills could install this compressor easily. I needed to drill three holes. The mounting plate has four holes, but I didn't use one due to mounting location restrictions.This is a good compressor and I hope to use it for many years. Good luck.Warning, Buyer beware, Seller shipped a defective item and refused to offer a refund. They led me in circles, trying to pass the responsibility off to others. Trust me, avoid the headaches and find another seller. The manufacturers of the ARB unit were much more pleasant to deal with.As said this product is totally overpriced by some $300.00 look for other sellers with in Australia.Works well but as said overpriced.There are a lot of scratches on both the black and blue portions of the compressor. It will still work properly, it's just disappointing for a "brand new" expensive compressor. I believe the compressor I received was refurbished, or a previously returned item.Pretty good, beats the super cheap ones from Crappy Tire. Could still be better but worth the money.The kit worked great for the use I had
