 A steering system for vehicles, for example snowmobiles. A strut-type suspension includes a fixed tube mounted to the chassis and a movable tube axially reciprocable in the fixed tube. A collar is mounted to structure attached to the chassis, and is rotatable around the axis of the movable tube. A scissors type linkage interconnects the collar and a ski, or a mount for a ski, or the movable tube. Preferably the collar includes an arm which extends rearwardly into the vehicle body.
