Aircraft landing gear

An aircraft landing gear comprising:

• a suspension mechanism which has a four-bar linkage and a shock absorber, wherein with the aircraft landing gear in a deployed configuration:
• the four-bar linkage comprises an upper link rigidly extending from an upper front pivot to an upper rear pivot, a lower link rigidly extending from a lower front pivot to a lower rear pivot, a front link rigidly extending from the upper front pivot to the lower front pivot, and a rear link rigidly extending from the upper rear pivot to the lower rear pivot;
• the lower link has a front wheel support and a rear wheel support, each wheel support being arranged to support one or more wheels;
• the four-bar linkage is configured to move between a lengthened position and a shortened position, the upper link and the lower link being closer together when the four-bar linkage is in the shortened position than when the four-bar linkage is in the lengthened position;
• the shock absorber is arranged to urge the four-bar linkage away from the shortened position and towards the lengthened position;
• and
• a length of the upper link is configured to be adjusted so as to change a distance between the upper front pivot and the upper rear pivot.
