Claim 8:
9. A vehicle suspension damper comprising:
a tube elongated along an axis;
a piston disposed in the tube and moveable relative to the tube along the axis;
a rod connected to the piston;
a floating piston spaced from the piston along the axis and moveable relative to the tube along the axis;
the tube defining a working chamber between the piston and the floating piston;
the tube defining a gas chamber, the floating piston separating the gas chamber from the working chamber;
the floating piston having a housing slideably engaged with the tube, the housing having an upper cage defining an upper chamber in fluid communication with the working chamber, the housing having a lower cage spaced from the upper cage, the lower cage defining a lower chamber in fluid communication with the gas chamber, and the housing including an upper segment having the upper cage and a lower segment having the lower cage, one of the upper segment and the lower segment including retention fingers that engage the other of the upper segment and the lower segment; and
