<p>In a snowmobile suspension system, it is known to provide suspension system adjustment with an eye bolt-nut combination which provides an increase or decrease in tension in a torsion spring which acts on a suspension arm of the suspension system. This invention replaces the eye bolt-nut combination with a rotatably mounted cam having surface portions in the form of channels arranged at different distances from its axis. A lateral arm of the torsion spring is accommodated within these channels and upon rotation of the cam, torsion spring tension is increased or decreased which provides the necessary stiffness to the suspension system.</p> |
