The present invention provides a pretensioned rubber suspension/dumper for vehicles axles. It consists of two concentric tubes, one exterior and the other interior, the exterior has integrated or wielded a force lever which articulates it with the vehicle axle, spring or rack through a bushing or perforated cross-beams and the interior tube or shaft has wielded two cross-beams of steel with a perforation at the tip, each of them articulate it to the vehicle axle, spring or rack and between the two tubes there is a mixture of natural and synthetic rubber adhered to their contact surface which when turning one inside the other, subdue the rubber to tension efforts; this system is characterized for being pretensioned in the factory to the required force and position to be used in the majority of vehicles with original car body fabricated at the plant. This system can be use in combination with the conventional suspension systems installed at the plant or as an integral suspension. It can also be applied as bumper between the axle and the chassis diagonally and as overload suspension between the axle and the chassis in a vertical position.
