Full kit install with springs, good quality affordable product!
Installed on a 2010 GMC 2500HD. Installed full kit along with Air Lift on board compressor and gauges. To start of with this seems to be a great product. Just installed it today. This is a long review but hopefully it will help the next person. Do not try to install this if you are a beginner DIY mechanic. I am by no means a professional but I have installed 100's of snow plows, spreaders, and de-icer systems so I do have plenty of experience with after market accessories. I would try this unless you're at least an intermediate mechanic, even if just for the necessary tools. All in all I probably had about 7 hours in the install (alone) but a good 1.5hr was just figuring out where I wanted to mount the compressor, gauges, and solenoid. I did the full kit with on board compressor. The kit came very well packaged in manufacturers boxing, all the hoses, hardware, pieces where there and packaged separately. I strongly suggest reading the instructions thoroughly a couple times before starting. They skip around a bit and have important notes but are not in order. Some of the instructions say to use a torque wrench which first of all most DIY guys dont even have. Unless it's just this kit, you will not be able to get a torque wrench on the upper bolts as it says to. Take your time and plan your install. You will need jack stands and a good jack. The instructions say to support the axel with jack stands which is incorrect. You'll want to support the frame with jack stands so you can use the jack to move the rear end up and down to accommodate installation. Do not mount the compressor under the hood. The heat will shorten the life. I had to call to ask where their suggested placement was cause it's not in the instructions and ended up mounting in on the inside of the frame out of any wheel splash areas. They actually answered the phone on a Saturday at 10a. With the airlines, btw not 1 leak after installed, take your time with your cuts. Make sure they are very cleanly cut and not beveled edges. I made sure my cuts were perfect and left plenty of slack not only for movement but incase I had to re-cut. I used a sharp razor. When you push them into the fitting you'll feel a slight pop, you need to push them in farther to seat the airline. This is probably where most people have air issues. They will slightly pop and then slide in an additional 1/8 to 1/4 inch. Practice before you try under the truck, the are easy to remove my pushing the pressure fitting in and pulling the hose back out. The compressor works great up to about 50lbs then it does slow down a bit but what would you expect from a tankless system under $200. Pumped up to 90lbs for test in about 3 or 4 minutes. When installing the wiring you will want a couple "add a fuse" kits to tie in to the fuse panels. Most parts stores have them for about $7. They are not in the kit. Last but not least I used the extra unions and 1 that I bought to run a single manual line to the rear bumber just incase the compressor goes out towing or just to keep a safe pressure in them for driving. Hope this helps a little.

I have a 2002 work van that carries some weight. I decided to go with air shocks to help level the ride, but I did not want to deal with having to fill the shocks anytime I needed to load the van. I decided to look around for an air lift system that would use an on-board compressor to add the needed air. I found the part while on Rock Auto. Their price was over $185.00. So I decided I should be able to find it for less money and I was right. Here on Amazon the price was $135 and shipping was free. The kit arrived with all the tubing, fittings, and the control and compressor. The manufacturer claims that it will fit ANY air shock system, which also prompted me to buy it. Before installing the system with the air shocks I purchased from Delco, I decided to see if everything fit. It appeared that the fittings and hose that came with the kit was larger than the lines that came with the air shocks. I decided to call the company to see if an adapter was available to make it work. It turns out they had nothing to make it work with the shocks I had. I felt a little disappointed since the package and the manufacturer stated it fits with ANY system. In order to make this work, I decided to head to Lowe's and visit the plumbing supply department. There I found a compression fitting that had the right threads for the shock and the the correct fitting for the air line. All for $1.97 for each fitting. Installed everything and it works great. No leaks and the compressor is not too loud.

Works well. Cheap switch and connectors.
This is a great kit and a whole lot more convenient than having to manually add air to the bags. I would have given it 5 stars. However my gauge showed up with a crack in the glass. Doesnt effect its operation. But kind of disappointing and don't want to deal with a return replacement. The switch and its mounting is the lowest grade garbage they could have used. I mean for the price it sure could have been better quality. Electrical connections they send with are also low grade trash. I replaced them all with solder and heat shrink. But get past the cheapness of the trinkets and the system does as it should. I ran it up to 100psi and it holds firm. The sensor to maintain 5psi works well. So overall if they would do better with the cheap switch and electrical connectors it would be a full on 5 star thumbs up.

Good controller for your air bag system.
It took a while to install in a good place and route the wires and compressor and air lines in a hidden spot. If you do it correctly, the system will work great and last a long time while not being in the way. I mounted mine in the place of the ashtray. I routed the air and electrical wires through the dash and under the sill plate to the back seat. I removed the rear seat of an extended cab pickup and mounted the compressor underneath in about the center of the truck. I tapped into a fuse in the driver's side dash panel. The install was clean, bit required disassembly of a lot of the interior and took a decent amount of time. I tapped into an interior light on the radio connector pigtail to get power for the gauge light.

2005年製TOYOTA TUNDRA SR5にRide Control Kit 59530と併せてマニュアル通りにDIYで問題なく取付。 マニュアルは英語なので翻訳が必要。シャシーに穴あけ加工があるので工具や車の配線に知識と作業経験がない場合は、専門業者に依頼することをお勧めします。コンプレッサー本体は荷台下に取付。Max7bar(100psi)までエアー充填する時間は約2分半程度。荷台が空の場合、Maxまでエア充填すると車高が約40〜50mm上がります。通常の走行の場合、1〜2bar程度エアーを充填するとロールの軽減と走りが柔らかくなり快適です。サポートエアサスなので車検も問題なく通ります。

It's a little pump so doesn't pump fast but it works good, I have 2x 3 bellow air bags so they take lots of air.

Good product for the price, makes my life a lot easier when i need to adjust the pressure in my bags. My Only concern is with the "T" connectors provided with the kit. They are VERY cheap plastic things and not one of them worked. Save yourself some time and go buy good ones before doing the install. After I got good T's the install was straight forward and everything works great. Overall, very happy with the unit has been working good for about a week now.
