A stabilizing jack is adapted for mounting on a single frame member of a trailer. The stabilizing jack includes a base channel, a drive screw rotatably mounted within the base channel and a lift leg connected at an upper end to a screw follower threadingly coupled to the drive screw such that rotation of the screw raises and lowers the lift leg. A stabilizing leg connected between the base channel and the lift leg provides support for the leg in the extended position. A stabilizing bracket projecting upward from a central web of the base channel is adapted for mounting to a trailer frame member. The stabilizing jack includes a mounting plate for fastening to the underside of the trailer frame member. Annular spacers on the screw follower are engaged by the stabilizing leg when retracted to resist rotation of the screw.
