Abstract: A snowmobile includes a plurality of ground engaging members, a frame supported by the ground engaging members, and a powertrain assembly supported by the frame. Additionally, the snowmobile includes a front suspension assembly supported by the frame. The front suspension assembly includes an upper control arm operably coupled to the frame and a lower control arm operably coupled to the frame. The lower control arm is forged. At least a portion of the lower control arm includes an artificially-induced area of localized stress, and the lower control arm is configured to absorb energy at the area of localized stress.
