General questions

To put it simply: incredibly reliable! The reliability of air suspension is highly dependent on the quality of the installation, just like any car modification. If you rush your install, or cut corners to “get the job” done this may come back to bite you. Truth be told, a carefully installed and well maintained air ride setup will last as long as any other aftermarket suspension. The bags themselves will outlive the life of the vehicle. If you won’t be installing your air suspension yourself, be sure to bring your vehicle and air ride components to a qualified and air ride experienced shop!



Air ride doesn’t call for much in regards to maintenance. We recommend emptying your air tank every couple of months, and if you have water trap(s) in your system we recommend draining those at least once a month. Both of these procedures are recommended to drain any moisture from the system, making both of these procedures less mandatory in dry climates. We find that it is convenient to drain water traps while you’re filling up your gas tank, and helps keep you in the habit.



Don’t worry! Leaks are very normal, especially with a new installation! That doesn’t mean that you should ignore a leak though, since they are very easy to track down. Grab any squirt bottle and fill it with a bit of soap and water, then begin spraying down any connection in your system. Even the slowest leak will cause bubbles to form. If the leak is audible and coming from a PTC fitting, be sure the air line is pressed firmly into the fitting. We have found that DOT approved fittings like those made by SMC are very reliable for PTC connections due to the inner “sleeve” that hugs the inside of the connected air line.



Digital systems provide preset heights using one of two methods: bag pressure or physical height-based measurement. Neither of these methods can be labeled as “better” than the other as they differ so much in methodology. One thing that must be understood about pressure-based presets is that pressure values are in no way a perfect means of determining the actual height of the vehicle. That is to say a vehicle could be the exact same height with 50 psi in all air springs or 100 psi in all air springs; it is totally dependent on the weight of the vehicle including passengers and cargo. The presets stored in a pressure-based controller are preset pressures, not preset heights. The user should monitor the physical height of the vehicle to ensure that the desired height is reached.

This is where the advantages of height-based managements, such as the AccuAir e-Level system become apparent. No matter what the weight inside the cabin is, a height-based management will remain consistent. Height-based systems like e-Level use height position sensors to determine the height of the vehicle rendering pressure values completely irrelevant. With e-Level you no longer have to deal with the hassle of installing pressure gauges. In a vehicle equipped with e-Level, you and four friends can hop in the car and your “drive preset” will be the same height as when it is just you in the vehicle. For a daily driver or vehicle that will be used to transport passengers, a true height based digital controller is the best option.

No. The vehicle can be lifted on a hoist for a short-term service work such as tire rotation or oil changes. However, if the vehicle will be on the hoist for a prolonged period of time, support the axle with jack stands in order to take the tension off the air springs.
