Suspension system with axle adjustment

A suspension system for supporting a vehicle chassis defining a longitudinal axis, said suspension system comprising

• an axle assembly comprising at least one axles positionable substantially perpendicular to said longitudinal axis;
• first and second trailing arms coupled with said axle assembly;
• and
• first and second pivotal links wherein said first pivotal link is pivotally securable relative to the chassis with a first pivotal connection defining a first pivot axis and a second pivotal connection couples said first pivotal link to said first trailing arm and defines a second pivot axis, wherein said second pivotal link is pivotally securable relative to the chassis with a third pivotal connection defining a third pivot axis and a fourth pivotal connection couples said second pivotal link to said second trailing arm and defines a fourth pivot axis, each of said first, second, third and fourth pivot axes being substantially perpendicular to said longitudinal axis and wherein said first and third pivot axes are substantially co-linear and positioned vertically above said third and fourth pivot axes;
• first and second adjustment mechanisms respectively engaged with said first and second pivotal links wherein movement of said first and second adjustment mechanisms respectively repositions said first and second pivotal links about said first and third pivot axes, pivotal movement of said first and second pivotal links about said first and third pivot axes respectively longitudinally repositioning said second and fourth pivot axes and thereby adjusting an angular position of said axle relative to said longitudinal axis.
