8 . The nested gas spring assembly of claim 7 , further comprising a collar encompassing an end of the extension rod external to the extension housing, the collar comprising a compression rod seal to seal against an outer surface of the compression rod and prevent the compression piston from being removed from the compression housing.
9 . A gas spring assembly for a vehicle steering stabilizer system, the gas spring assembly comprising:
a compression housing including a hollow cavity;
an extension rod; and
a compression rod operable to be positioned within the hollow cavity of the compression housing, the compression rod comprising:
an extension housing including a hollow cavity for receiving the extension rod therein,
wherein the extension rod is biased into the hollow cavity of the extension housing of the compression rod via a first force provided by an expanded gas within the extension housing,
wherein the compression rod is biased out of the hollow cavity of the compression housing via a second force provided by a compressed gas within the compression housing.
10 . The gas spring assembly of claim 9 ,
wherein in an extension position a substantial portion of the extension rod is external to the hollow cavity of the extension housing and a substantial portion of the compression rod is external to the hollow cavity of the compression housing.
11 . The gas spring assembly of claim 10 ,
wherein in a neutral position a substantial portion of the extension rod is internal to the hollow cavity of the extension housing and a substantial portion of the compression rod is external to the hollow cavity of the compression housing.
12 . The gas spring assembly of claim 11 ,
wherein in a compressed position a substantial portion of the extension rod is internal to the hollow cavity of the extension housing in the compression rod and a substantial portion of the compression rod is internal to the hollow cavity of the compression housing.
13 . The gas spring assembly of claim 9 , further comprising:
an extension piston disposed at an end of the extension rod, the extension piston sized to seal against an inner diameter of the extension housing,
wherein the extension piston comprises a narrow end.
14 . The gas spring assembly of claim 13 , further comprising:
an end stop disposed at an end of the extension housing, the end stop comprising an opening for receiving the narrow end of the extension piston.
15 . The gas spring assembly of claim 9 , further comprising:
a compression rod seal disposed in the compression housing, the compression rod seal sized to seal against an outer diameter of the compression rod.
16 . A nested gas spring assembly comprising:
an extension housing including a hollow cavity therein;
an extension rod including a compression housing with a hollow cavity therein, wherein at least a portion of the extension rod is received into the hollow cavity of the extension housing;
a compression rod with at least a portion thereof received into the hollow cavity of the compression housing of the extension rod;
a first collar encompassing a first end of the extension housing;
a second collar encompassing a second end of the extension housing opposite the first end; and
a third collar encompassing an end of extension rod external to the extension housing,
wherein in an extension position a substantial portion of the extension rod is external to the hollow cavity of the extension housing and a substantial portion of the compression rod is external to the hollow cavity of the compression housing,
wherein in a neutral position a substantial portion of the extension rod is internal to the hollow cavity of the extension housing and a substantial portion of the compression rod is external to the hollow cavity of the compression housing,
wherein in a compressed position a substantial portion of the extension rod is internal to the hollow cavity of the extension housing and a substantial portion of the compression rod is internal to the hollow cavity of the compression housing in the extension rod,
wherein a first force provided by an expanded fluid within the extension housing biases the extension rod into the hollow cavity of the extension housing, and
wherein a second force provided by a compressed fluid within the compression housing biases the compression rod out of the hollow cavity of the compression housing.
17 . The nested gas spring assembly of claim 16 , further comprising:
a compression rod seal disposed in the compression housing of the extension rod, the compression rod seal sized to seal against an outer diameter of the compression rod.
