1. A shock assembly comprising:
a main chamber comprising a fluid therein;
a pump tube disposed within said main chamber;
a damping piston coupled to a shaft, said damping piston disposed in said main chamber to divide said main chamber into a compression side fluid chamber and a rebound side fluid chamber;
an automatic ride height adjustment assembly comprising:
a tube-in-shaft pump assembly; and
a spring preload piston assembly;
wherein said tube-in-shaft pump assembly comprises:
an intake/exhaust port through a portion of said pump tube; and
a fluid path from said pump tube to said spring preload piston assembly,
wherein motion of said damping piston along said pump tube during a compression stroke pumps said fluid through said pump tube and into said spring preload piston assembly; and
wherein a SAG ride height is established by an axial location of said intake/exhaust port of said pump tube.
