A unitized hydraulic suspension system for a tandem front and back two-axle group comprises two pivoting arms, each for supporting one of the two axles, arranged on opposite sides of a common rigid hanger. Each arm is attached to one end of a respective cylinder the other end of which cylinder is attached to the common hanger. The unitized hydraulic suspension simplifies the use of hydraulic suspension in dual laning heavy haul applications by the provision of a slide assembly in which unitized hydraulic suspensions are slidably mounted so as to be extendible or retractable in relation to one another.
