A resilient strut adapted to secure an aerodynamic skirt to a trailer is provided, the aerodynamic skirt comprising a skirt panel including a front portion and a rear portion adapted to be substantially longitudinally mounted to the trailer, the front portion being adapted to be mounted toward a forward portion of the trailer and the rear portion being adapted to be mounted toward a rear portion of the trailer in an aerodynamic configuration, the skirt panel being adapted to move away from the aerodynamic configuration when contacting a foreign object and to recover its aerodynamic configuration thereafter, the resilient strut adapted to sustain an elastic deformation allowing the resilient strut to bend when a load is applied to the resilient strut when the skirt panel moves away from the aerodynamic configuration and to self-recover its original shape when the load is removed. A kit of resilient struts, a method thereof and a trailer equipped with same are also provided.
