A stabilizer for all terrain vehicles which has a mounting bracket (20) attached to the undercarriage to which an outrigger spring (22), (22a) or (22b) is mounted at a forward angle. A rear spring (30) extends aft of the vehicle in similar manner. Stabilizer arms (26) and (32) are juxtapositionly attached to the springs and act as snubbers, allowing limited deflection of the springs. A folded runner section (23) or a pair of outrigger feet (28), having an upwardly tapering end are integral or attached to the outrigger springs and a cross bar (34) is fastened to the rear spring providing an extended footprint capable of holding the weight of the vehicle. Another embodiment employs a pair of integral ''U'' shaped outrigger springs (22b) with stabilizer arms (26) extending both to the sides and the rear of the vehicle. The spring or springs are so located as to change the center of gravity preventing the overturning of the vehicle while yieldingly absorbing the load if an obstruction is encountered.
