Abstract: Disclosed are a system and method for operating a vehicle kneeling system. A controller operates an actuator that compresses the vehicle suspension to lower the frame of the vehicle to a kneeled position. The controller verified that the transmission is set to park, and that a kneel switch is depressed, to operate the actuator. The controller continues to monitor these parameters, and when the controller detects loss of a signal, it deactivates the actuator which allows the suspension to return the vehicle to a ride height.
Abstract: Disclosed is a variable length shackle assembly that includes a first frame member that includes a vehicle frame mount and a rail support and a second frame member that includes a leaf spring mount and a guide rail that cooperates with the rail support to permit the first frame member to move linearly relative to the second frame member while resisting non-linear movement and a biasing member such as a spring that connects that first frame member to the second frame member.
