ABSTRACT:
A ski suspension strut for a snowmobile comprises: upper and lower telescopically arranged members guided for a predetermined range of relative axial movement but constrained against relative rotation. The lower member is of cylindrical profile and is rotatably supported in a fixed generally upright orientation by mounting means in the snowmobile. One end of the lower member is connected to a snowmobile ski and the second member is connected to a steering mechanism in the snowmobile to be rotated thereby in effecting steering movement of the ski. Damper means is located interiorly of the lower member and operatively connected to both members to dampen relative axial movement thereof. Linear bearing means are mounted in the lower member in sliding engagement with a section of the upper member that is of constant square profile over a suitable length.
