PACBRAKE AIR SPRINGS- #1 ON THE MARKET Pacbrake’s truck air bags ( air springs ) allow you to easily level out your truck’s stance for any towing / hauling situation with the ability to adjust the amount of air in each (bag) spring. Filling the springs can be done in two ways, the most standard being our manual fill kits that provide you with easily accessible fill valves located near your rear license plate OR the more convenient option would be adding onboard air to your truck and operating your air suspension system right from the driver’s seat. Pacbrake air springs work in addition to your existing suspension, not as a substitution. It is important to note that by installing an air suspension kit, your max load capacity (GVWR) does not increase.
Pacbrake Air Springs are designed and manufactured to be the #1 air suspension choice among consumers.
