Methods and apparatus for suspension adjustment

A shock absorber for a vehicle having a gas spring movable between an extended and compressed positions, comprising

• a gas spring housing;
• a damper body telescopically movable relative to the gas spring housing;
• a trigger, the trigger located on one of the members and operable when the members are in a predetermined position relative to each other;
• a bleed valve for bleeding compressed air from the gas spring as the gas spring housing and damper body move telescopically from the extended to the compressed position, the valve operated by the trigger and the valve initially open and subsequently closed by the trigger;
• a pump for adding compressed air to the gas spring at a first location and for proving compressed air to the bleed valve at a second location;
• and
• a first and second lock out members to prevent operation of the bleed valve.
