Air Systems

Originally exclusive to heavy trucks and buses, and more recently original equipment on luxury cars and SUVs, today no matter what you drive you can get the smooth ride, load leveling capability, improved stance and superior handling that can only come from air suspension. Whatever you do with your vehicle - haul heavy loads, tow campers or trailers, cruise the boulevard and display at car shows, or race at the track, we have air suspension components and complete systems that will deliver the ride, look, and performance you want.

Air suspension systems can be divided into two basic categories: supplemental and replacement. Supplemental air springs, also known as “helper springs”, are designed to work with your existing coil or leaf springs, to level the vehicle and improve performance and driving safety when hauling cargo or towing. Replacement systems are installed in place of your existing suspension components to adjust ride height and ground clearance and allow suspension tuning to improve handling - the perfect set-up for show cars and performance driving.

When a pickup with OE suspension has a big load in the bed or is towing a trailer, the rear of the truck may squat, with the headlights aimed at the sky. Because the weight is unevenly distributed on the tires, handling and braking suffers. Supplemental leaf springs or cargo coils may provide additional load support, but at the cost of decreased ride comfort, and they can't be adjusted to the load. In contrast, air springs are completely adjustable, so you can level your vehicle for optimal handling and braking, proper wheel alignment and headlight aim, and get a comfortable ride. These springs install on top of the leaf springs or axle, or fit inside the coil springs. For select applications, we also have passive-to-active suspension conversion kits that completely replace the coil springs.

To get the most benefit from your air springs, install an on-board air compressor system. We have complete systems that include the compressor, air springs, air lines and fittings, mounts and hardware, and everything needed for installation, as well as compressor systems that can be used with any brand air springs. Instead of having to find a source of air when you want to pump up your air springs, with an on-board compressor system you can adjust air pressure, and the load support and level of your truck, with the touch of a button. We offer systems that adjust air springs individually or simultaneously, with hardwired control, wireless control with no wires or air lines running into the cab, or automatic control in response to an electronic height sensor.

If you want that ground-hugging look for your show car, or want to cut lap times at the track, nothing beats an air suspension system. Your original equipment springs or struts are replaced with infinitely adjustable air springs or struts. If you have a custom cruiser you can slam it without the harsh ride typical of lowered coil springs, and easily raise it up with the touch of a button to clear speed bumps and steep driveways. For performance cars we have struts that come with adjustable progressive rate air springs, and adjustable damping, for ride height adjustment, resistance to body roll and dive, precise suspension tuning, and responsiveness that rivals the best coilover systems, yet provides a comfortable highway ride.

But as beneficial as aftermarket air suspension systems are for hauling heavy loads or performance driving, original equipment systems are not without their problems. OE systems can be complex, and include many parts that fail due to age and wear: air bags deteriorate and get punctured, air lines leak, and compressors burn out from continuous operation trying to keep a leaky system filled. Repairing these defects can be prohibitively expensive so we offer active-to-passive, coil spring conversion kits as an affordable alternative. The springs and shocks in these kits are specifically designed for each application; they'll bolt right on in place of troublesome OE air suspension components and provide a comfortable, maintenance-free ride.
