Abstract
A method and apparatus for adjusting the sag setting of a vehicle suspension are disclosed. An integrated damper/gas spring shock absorber includes a bleed port located at a position on a gas spring cylinder corresponding to a desired sag setting. The gas spring may be over pressurized to a pressure above the expected operating pressure of the gas spring. The vehicle may then be loaded with the normal operating load, partially compressing the shock absorber. Opening the bleed port allows gas to vent from the gas spring, further compressing the shock absorber until a piston in the gas spring closes the bleed port from the inner surface of the gas spring cylinder. A sleeve may be inserted over the gas spring cylinder, the sleeve including one or more sealing elements that seal the bleed port from the outer surface of the gas spring cylinder during normal operation.
