ABSTRACT:
An improved rear suspension assembly is provided for snowmobiles, which includes a link assembly operatively connecting the rear suspension arm to a front cushion absorber so that the pivot movement of the rear suspension arm actuates the front shock absorber assembly. In one embodiment of the present invention, a rocker arm is pivotally attached to the slide frame assembly and has a front end thereof pivotally attached to the front shock absorber assembly, and has a rear end pivotally attached through a link rod to the rear suspension arm. The present invention advantageously improves the dynamic response of the rear suspension during snowmobile acceleration, and therefore prevents the skis of the snowmobile from lifting off from the ground.
