1. Inflate and deflate the system (do not exceed 125 PSI) to check for clearance or
binding issues. With the air springs deflated, check clearances on everything so as
not to pinch brake lines, vent tubes, etc. Clear lines if necessary.
2. Inflate the air springs to 75-90 PSI and check all connections for leaks.
CAUTION: MAKE SURE THE FRONT WHEELS ARE STRAIGHT WHEN DEFLATING AND REINFLATING AIR BAGS.
Suspension damping is a matter of compromise. Setting it too stiff will make the ride feel jarring. In addition, if the suspension is too stiff, the tires will lose contact with the road, reducing control and power delivery. On the other hand, if the suspension is too soft, the car can experience brake dive and excessive bouncing. The sweet spot lies somewhere in the middle. Air Lift dampers have a range of adjustment, which allows the driver to tune the ride and handling to his or her preferences.
Air Lift recommends damper and air pressure settings for every vehicle kit, but it is impossible to consider every situation. For example, even though Air Lift kits replace the dampers and springs, vehicles with sport-tuned suspensions might have stiffer bushings, larger anti-roll bars, bigger wheels, wider tires, etc. These settings may need to be adjusted to different vehicles and driving characteristics.
1. The dampers in this kit have 30 settings, or “clicks,” of adjustable compression and
rebound damping characteristics. Damping is changed through the damper rod using
the supplied adjuster (Figs. 21 & 22) or an 3mm hex key (not included).
2. Turn the adjuster clockwise (H) and the damping settings are hardened, reducing
oscillations and body motion. Turn the adjuster counterclockwise (S) and the
damping is softened.
3. Each damper in this kit is preset to “-17 clicks.” This means that the damper is
adjusted 17 clicks away from full stiff, which starts at 0. Counting up from full stiff
is the preferred method of keeping track of, or setting, damping. This setting was
developed on a 2015 Ford Mustang 2.3L EcoBoost.
