AIRSHOK™ Setup Instructions
Spring Rate
Determine what the initial spring rate of the AIRSHOK™ will be. This is set with the gas pressure. For every 1 PSI of gas pressure, you will have 2.4 pounds of spring force.
Spring Rate / 2.4 = PSI
So, if you want 120 pound initial spring rate: 120 / 2.4 = 50 PSI.
Play with the gas pressure in 10 PSI increments until you are happy with the traction.
Adding gas pressure will make the spring rate stiffer through the whole range.
Subtracting gas pressure will make the spring rate softer through the whole range.
Rising Rate
The rising rate of the spring is determined by the gas volume inside the shock. The more gas volume that there is, the more linear the spring rate will be.
For a more progressive spring rate, oil is added to the AIRSHOK™ to decrease the gas volume. The more oil that is added, the more progressive the spring rate will be.
Add oil in 10cc increments until you achieve the force you want at full travel.
