An anti-darting ski for snowmobiles, the ski including a longitudinally extending runner with a central keel. A generally flat wear strip with two skags is attached to the bottom of the keel. The wear strip is contoured to match the bottom surface of the keel. The skags are laterally spaced beneath the wear strip such that their inside surfaces do not extend towards each other. The skags and wear strip may be mounted flush with the outside edges of the keel. The skags may also be located asymmetrically about a longitudinal center point of the ski. The dual skag system acts to minimize darting of the snowmobile in the snow.

Anti-dart snowmobile ski

A snowmobile having an adjustable ski stance. The snowmobile including a central chassis from which an endless track is suspended and straddle type seat is supported. A pair of skis are coupled to a front suspension and are operatively linked to a handlebar assembly for steering the snowmobile. The skis are coupled to the snowmobile by spindles coupled to the suspension and each ski. A bushing with an offset flange couples the spindle to the ski and provides for ski stance adjustment.

Snowmobile having an adjustable ski stance

A suspension system mountable to the chassis of a snowmobile and about which an endless track is carried. The suspension includes a slide frame for engagement with a lower portion of the endless track and one or more springs for urging the slide frame downwardly away from the chassis. The suspension system also includes a downwardly angled suspension arm having an upper end pivotally mounted to the snowmobile chassis. The lower end of the arm is pivotally connected to the slide frame so as to permit limited longitudinal movement of the lower end of the arm with respect to the slide frame. An adjustable limit is provided for adjustably limiting the degree of longitudinal movement of the lower end of the arm with respect to the slide frame to adjustably control the range of orientations of the slide frame with respect to the snowmobile chassis.

Adjustable snowmobile track suspension

A suspension system mountable to the chassis of a snowmobile and about which an endless track is carried. The suspension includes a slide frame for engagement with a lower portion of the endless track and one or more springs for urging the slide frame downwardly away from the chassis. The suspension system also includes a downwardly angled suspension arm having an upper end pivotally mounted to the snowmobile chassis. The lower end of the arm is pivotally connected to the slide frame so as to permit limited longitudinal movement of the lower end of the arm with reset to the slide frame. An adjustable limit is provided for adjustably limiting the degree of longitudinal movement of the lower end of the arm with respect to the slide frame to adjustably control the range of orientations of the slide frame with respect to the snowmobile chassis.

A snowmobile ski comprising a longitudinally extending runner having a bottom surface, a generally flat elongate bar having a top and bottom surface, and a steering skag extending longitudinally of the runner on the bottom side of the bar. The flat bar is generally contoured to abut the bottom surface of the runner, and furthermore extends forwardly beyond the skag and laterally and longitudinally beyond the skag so that a skag track in the snow encountered by the ski and the skag track left by the skag in the snow will be at least partially filled in by the bar.
