<p>A snowmobile slide rail suspension system is shown in which the suspension frame, having spaced side frame members each formed from a pair of metal stampings, is positioned between the upper and lower runs of the drive track. The snowmobile body is supported on the frame by pivotable front and rear arms. A pair of torsion springs have their central portions and one end portion of each secured to the read arms and have their other end portions carried by spring support members extending rearwardly from the front arms at their pivotal connection with the frame, to thereby bias the front and rear arms away from the frame.</p> |
