66283-1039 In a snowmobile track suspension, the slide frame is supported upon downwardly and rearwardly angled front and rear suspension arm assemblies. The suspension arm assemblies are of similar construction, length, and orientation, having upper ends connected to fixed pivots in the snowmobile chassis and lower ends pivoted to the slide frame. The lower end of the rear suspension arm assembly has a pivot mount that is movable longitudinally of the slide frame. Movement in the forwards direction being blocked by an abutment which ensures that during suspension travel the front end of the slide frame cannot move higher than the rear end thereof.
