This invention relates to a device and an adjustment method of stabilizing a vehicle chassis through an auxiliary leaf spring. An auxiliary leaf spring is installed above a suspension spring on two ends of a rear axle. The rear axle is held between the suspension spring and the auxiliary leaf spring. In order to connect the suspension spring to the auxiliary leaf spring, adjustable shackle assemblies are set on two ends of the auxiliary leaf spring. In addition, two ends of the auxiliary leaf spring are disposed with shackles, and a rubber damper to which the shackles of the auxiliary leaf spring can apply tension is provided between the center of the auxiliary leaf spring and the rear axle. Accordingly, a compact structure and an easily adjustable effect can be provided, and the holding force between the suspension spring and the auxiliary leaf spring makes the chassis more stable, by which the inclination of the vehicle can be controlled; meanwhile, the rear part of the vehicle can be prevented from incline
