Title: Snowmobile suspension system

Abstract: A snowmobile suspension system including a tread, a supporting frame for the tread, and front and rear suspension means suspending the frame beneath the body. The rear suspension means includes co-acting support arms and control levers permitting the relative movement between the frame and the body to exceed the movement between the support arm and frame, thus reducing the likelihood of the body striking, or "bottoming out", against the frame.
