Yes. Whether you have manual fill valves or in-cab controls with onboard air, you can easily adjust each air spring’s pressure to level out your vehicle. The manual fill valves are installed so that the fill valves are easily accessible, usually positioned out of the license plate at the rear of the vehicle. In-cab controls (with onboard air) allow you to adjust each air spring’s pressure from the comfort of your driver’s seat.
No, the air springs are an addition to your existing suspension, not a substitution. kits are easily installed and do not affect your vehicle’s factory suspension.
No. You must never exceed your GVWR (gross vehicle weight rating). The air springs simply provide you with added support and therefore better control for an overall smoother, safer ride.
No. The installation is fairly simple and can usually be completed within 2-3 hours. If installing the kit with an onboard air system, the installation procedure is a little different and may vary depending on the vehicle application
Not necessarily. The maximum total weight that the vehicle has been designed for, the GVRW (Gross Vehicle Weight Rating), needs to be followed. Violation of the GVWR can result in fines, loss of liability insurance, or overwhelm your vehicle's brakes or drivetrain. Check your vehicle's owners manual for the rating.
It is advised to keep about 10 PSI in the springs even with no load. This allows the spring to keep its "shape" preventing chafing.
Pacbrake offers 3 different lengths of air spring spacers to accommodate customers with lifted trucks up to 6 inches. See part numbers HP10152, HP10154, and HP10156.
If properly maintained and if regular pressure checks are conducted, the air springs will never have a problem. Pacbrake offers a lifetime warranty on all our air springs.
