Claim:
1. A jack apparatus adapted to lift a low rider vehicle having components defining a ground clearance of less than 2 inches vertically and that define with vehicle tires a generally triangular low clearance space, comprising: an upper subframe having a pair of horizontally-adjustable lift arms adapted to extend into the low clearance space and engage front and rear surfaces of the tire; a lower subframe having a pair of ground-engaging legs configured to fit into the low clearance space with the lift arms and that are located generally under the lift arms when the lift arms are raised; the lower subframe including at least one horizontal beam mount comprising a slot, the horizontal beam mount extending substantially perpendicular on at least one side of the lower subframe and wherein the pair of ground-engaging legs include a slot engaging fastener for engaging the slot of the horizontal beam mount for laterally adjusting the ground engaging legs on the horizontal beam mount; and a scissor lift mechanism attached between the upper and lower subframes but not located under the lift arms so that the lift mechanism operates from a position outboard of the vehicle; the scissor lift mechanism including a first upper axle rotatably secured to the upper subframe on a vehicle-adjacent lift-arm-adjacent side of the upper subframe and including a first lower axle rotatably secured to the lower subframe on a vehicle-adjacent lift-arm-adjacent side of the lower subframe; the lift arms being movable between a fully-collapsed lowest position where the arms are each laterally adjacent the associated legs, and movable to vertically lifted positions above the lowest position; and the scissor lift mechanism including a threaded screw attached horizontally to the upper subframe and that moves with and remains constantly horizontally adjacent the upper subframe when operating the lift mechanism between lower-most and raised positions.
