1. A gas spring for a vehicle suspension, the gas spring comprising:
a cylinder;
a rod movable relative to the cylinder, the rod and the cylinder at least partially defining a chamber having a variable volume and containing a first pressurized gas; and
an accumulator in communication with the chamber and containing a second pressurized gas;
wherein the gas spring provides a variable spring rate based on a pressure of the first pressurized gas relative to a threshold pressure.
