The bracket arm has an end fixedly connected to the lower portion of the suspension arm. The rocker arm has an upper end pivotally connected to the other end of the bracket arm and a lower end supporting a lower end of a shock absorber, the lower end of said shock absorber being pivotally attached thereto. The upper end of the shock absorber is pivotally interconnected to the chassis. The rocker arm is constructed and arranged such that a lower end thereof is disposed beneath the lower portion of the suspension arm.
