1. A suspension system for a track system, the suspension system comprising:
a first suspension member pivotally connectable to a frame assembly of the track system, the first suspension member defining a receptacle;
a second suspension member pivotally connectable to the frame assembly of the track system, the second suspension member extending at least partially within the receptacle and being moveable relative to the first suspension member;
a resilient member having a first surface and a second surface, the first surface being generally fixedly connected to the second suspension member and the second surface being generally fixedly connected to the first suspension member; and
the first and second suspension members have a first position, and in response to the first and second suspension members being offset from the first position, the resilient member biases the first and second suspension members toward the first position;
wherein the frame assembly includes a first frame member and a second frame member, the first and second frame members being pivotally connected to one another about a first pivot.
