Suspension hydraulic lift actuator

A suspension hydraulic lift system having a collapsed position and an extended position comprising:

• a stepped support tube having a first section and a second section, said first section having a first diameter, said second section having a second diameter, said first diameter being less than said second diameter defining a tube shoulder between said first and second sections;
• a housing having a fluid passage in fluid communication with a fluid chamber, said housing is mounted about said stepped support tube;
• said fluid chamber is adjacent said second section, when said suspension hydraulic lift system is in said collapsed position, and said fluid chamber is adjacent said first section when said suspension hydraulic lift system is in said extended position;
• said fluid passage and said fluid chamber is adapted to receive fluid to act upon said tube shoulder to collapse and extend said housing and said stepped support tube relative to one another.
