Abstract
Abstract A cushioned support means for use with snowmobiles is provided which comprises two laterally aligned sleeves formed through the bottom of the snowmobile which have support shafts extending therethrough. A shock absorber is affixed to the upper end of each of the support shafts and a means for attaching skis is affixed to the lower end of each of the support shafts. Coil springs encircle each of the support shafts and urge the shafts downwardly. The support shafts are preferably rotatable about their longitudinal axes and movable upwardly and downwardly along these axes and are utilized as a portion of the steering apparatus for the snowmobile.
