1. 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 an upper segment with an upper cage, the upper cage defining an upper chamber, the upper cage having a passageway extending from the upper chamber to the working chamber;
the floating piston having a lower segment with a lower cage, the lower cage spaced from the upper cage, the lower cage defining a lower chamber, the lower cage having a passageway extending from the lower chamber to the gas chamber; and
one of the upper segment and the lower segment including retention fingers that engage the other of the upper segment and the lower segment;
the floating piston having a membrane fluidly separating the upper chamber and the lower chamber, the membrane being flexible relative to the upper segment and the lower segment.
