Abstract
A snowmobile has a tunnel and a rear suspension assembly. The rear suspension assembly includes at least one rail for engagement with the endless drive track and at least one suspension arm. At least one torsion spring is coupled to the at least second suspension arm. The at least one torsion spring has a first end contacting the rail and a second end. A torsion spring adjuster is fixedly connected to the at least one suspension arm. The torsion spring adjuster receives the second end of the at least one torsion spring. An actuator is operatively connected to the torsion spring adjuster. The actuator is located at least partially outside the tunnel. The actuator operates the torsion spring adjuster to move the second end of the at least one torsion spring relative to the first end of the at least one torsion spring.
