Air Spring / Air Suspension Kits

Your truck’s suspension was designed as a compromise between capacity and ride comfort. So, when you haul heavy loads or pull a trailer, the rear springs can be pushed to their limit, resulting in excessive bounce, sagging ride height, and an overall feeling of instability. It doesn’t have to be this way. When towing or hauling, there are multiple ways to negate the negative effects of heavy loads. With the simple addition of an adjustable air suspension, such as automotive aftermarket air helper spring kits, you can eliminate overtaxing your suspension by providing the extra support of an inflated air spring, resulting in a level stance, improved ride quality, stable handling, and an overall suspension upgrade based on specific needs. No. You must never exceed your GVWR (gross vehicle weight rating). The air springs provide added support and, therefore, better control for an overall smoother, safer ride.


  • Applications for light duty and medium duty vehicles
  • Added support for an overall smooth and safe ride
  • Eliminates vehicle sag, sway & bottoming out
  • Front-to-back and side-to-side adjustability
  • Ideal for heavy haulers or unevenly distributed loads
  • Lifetime warranty on air springs

Pacbrake Wireless Controls

Pacbrake Wireless Air Spring Controls got even better! The pre-assembled control board of this premium kit now features a built-in heavy-duty air compressor for total control of the air springs.

Who needs another remote control? Pacbrake Wireless Air Spring Controls allow you to adjust your air spring pressure from your phone with the touch of a button. It is the perfect means to control your vehicle’s air suspension system, while ensuring QUALITY, DURABILITY, and VALUE. Adjust your air springs independently from inside and outside of the vehicle. The Pacbrake Wireless Controls also allow you to activate functions such as speed bump control, hump control, slope control, and high-speed driving control under the air suspension control.


  • An easy-to-use app that reads real time pressure feedback within each air spring. The app has 3 built-in memory presets so you can quickly achieve your desired air spring pressure.
  • Military grade solenoids designed to withstand extreme environments
  • IP67 rated controller that is waterproof and debris resistant
  • Accessible components offer ease of serviceability and replacement of parts
  • Pre-assembled control board with air compressor, plug and play harnesses for easy install
  • ¼ hp oil-less 12 VDC compressor, with sealed bearings
The Pacbrake Wireless Controls are a universal fit – They fit the frame of any vehicle and work with any air spring on the market. Proudly made in Canada, the Pacbrake Wireless Controls have a 2-year warranty. *



The STABLELOAD® suspension enhancement, designed for rear springs, works with your existing leaf spring suspension to provide up to 2,000 lbs. of load-leveling capacity. It dramatically improves vehicle handling characteristics by “pre-activating” the stabilizing effect, keeping the rear springs actively under load as your vehicle factory engineers intended. The Quick Disconnect STABLELOAD® design, specifically engineered for the lower overload springs, offers astounding safety and vehicle handling improvement. Putting the robust lower overload to work sooner stabilizes the vehicle’s suspension, making it safer for both passengers and load. This STABLELOAD® design is the most effective, as the lower overload springs are generally over 30% stronger than the upper overload springs. The STABLELOAD® is also the only suspension enhancement that can be turned on and off with the lower leaf spring design, allowing you to return to your factory ride when not towing or hauling. All STABLELOAD® kits work equally well with or without aftermarket air suspension.

The Quick Disconnect models for the lower overload spring incorporate a unique design that allows the STABLELOAD® to quickly engage or disengage your lower overloads, enabling you and your passengers to ride in safety and comfort when towing or hauling and to quickly return to the original ride in just seconds when not towing or hauling. This is accomplished by attaching each of the STABLELOADs® onto each overload end (front and rear passenger side, front and rear driver side). The Quick Disconnect STABLELOAD® Series is designed with a tapered wedge mounted to a hinge mechanism that allows the STABLELOAD® to be hinged in or out of engagement in seconds using a common 3/8″ ratchet extension and ratchet. Each precision-crafted STABLELOAD® kit carries our Legendary Lifetime Warranty and is proudly made in the USA.

Stainless Steel STABLELOAD® Quick Disconnect

The STABLELOAD® is the only overload suspension system that follows the two major truck manufacturing laws of suspension:

  • Law 1: Must be uncompromisingly comfortable as a passenger vehicle
  • Law 2: Must ride safely without compromising comfort while towing and hauling
  • Dramatically improves safety, handling, body roll and porpoising while towing and hauling
  • Ability to turn on and off in seconds (Applies only to the Quick Disconnect Lower Overload).
  • Made of stainless steel to keep the STABLELOADs® looking new without a layer of protective powder coat
  • Universal fit for all vehicles with factory-installed upper or lower overloads
  • Quad contact design complements the vehicle’s specially engineered suspension that automotive manufacturers have invested millions of dollars in designing.
  • Enhances airbag performance by lowering airbag overload air pressure and activating the factory overloads

  • Kit includes four STABLELOADs® (outfits one complete vehicle)
  • Legendary Lifetime Warranty includes coverage for the vehicle factory leaf springs
  • Made in the USA
