We have created the perfect suspension kit to tear up a racetrack, shred some back country roads, or to stop people dead in their tracks at a show.  As the leader in aftermarket high-performance air suspension, we know what it takes to balance your ride perfectly, maximize handling capability, and maintain your ride’s stunning good looks. 

So, what does it take to have such a versatile suspension system? It all starts with a strong foundation; in this case, that’s the struts. Air Lift Performance uses 30-way adjustable, monotube struts (with a serious range of damping adjustment) that have been specially tuned to match the air springs.  Monotube construction is the preferred choice in racing, and for us as well,  considering its sensitivity to small inputs as well as its great ability to shed heat when pushed to the limit.  The 30 clicks of adjustment aren’t just for fun, but allow users to dial in their preferred handling feel or desired ride quality.  The range goes from super-stiff to exceptionally soft, adjusting rebound and compression together. The struts weigh considerably less than the coil spring parts you remove, reducing unsprung weight—a benefit to both ride control and handling.

Another notable feature is the presence of adjustable camber plates in front. This allows easy, precise adjustment of the camber angle, making quick work of the alignment process for road or track.  These plates are packed with high-quality, Japanese-manufactured pillow ball bearings for long life and low noise.

What sets these struts way apart from the coilover crowd is the addition of our adjustable, progressive-rate air springs.  These high-rate springs create a stable platform for aggressive track driving, while providing a level of comfort not typically found with lowered suspensions. By using this progressive nature of air springs and maximizing available suspension travel, we are able to ride low without the punishing ride…and since they allow ride height to be adjusted with a button, no longer do you have to suffer the curses of static suspension lowness!  No more issues with scraping against speed bumps or steeply angled drives. Raise it up as high as stock to ride off-road without damaging the underbody.

Having good components in a kit is important, but it’s just as critical to make sure they work together to give the desired result. Extensive testing at various racetracks has proven to be important in creating the proper handling balance, as well as illustrating the toughness and durability of the parts.

Worried about installation?  Every kit comes with a detailed instruction manual to guide you through all the steps. If you can install suspension and wire a stereo, you have the skills necessary for the job.  And if you have questions, our customer service department will take good care of you.

Our LEVEL 4 kit represents the way we'd build your ride if it was ours!  In this case, Viair 480C air compressors and an AccuAir valve manifold with their eLevel automatic ride control, with everything else from the LEVEL 3 system carried over.  Sure, you can still spend more money on chrome air tanks and such, but the equipment in this package is the highest quality for your ride!

We include complete installation guides for the installation of the airbags, as well as plumbing and wiring diagrams to make things as painless as possible.  Feel free to ask any questions about putting this kit in and we'll be happy to assist!  We love hearing from our customers and seeing their projects come together.
