Abstract: A RevoKnuckle-type suspension for a wheeled vehicle has a hub mounted to a bearing carrier for rotation relative thereto about a steering axis, and a shock absorber connected non-rotatably to the bearing carrier. The shock absorber has an outer cylinder having an axially-extending guide hole defined therein, and a piston and attached piston rod retained for axial reciprocation in the guide hole. The guide hole and at least one of the piston and the piston rod retained therein have respective complementary-shaped, non-circular cross-sectional shapes which engage one another to resist axial rotation of the piston and/or the piston rod within the guide hole. The carrier is therefore restrained against rotation relative to the vehicle sprung structure without the need for any additional component(s) such as a control arm or stabilizer, as required in a traditional RevoKnuckle-type suspension.
