1. A height adjustable top mount for adjusting a ride height of a vehicle comprising:
a top plate configured to mount to a body of the vehicle and movable between a first position and a second position;
a worm wheel received in the top plate and including an inner wheel surface and an outer wheel surface that opposes the inner wheel surface;
a core received within the worm wheel and helically meshed to the inner wheel surface of the worm wheel;
a worm gear meshed to the outer wheel surface of the worm wheel,
wherein rotation of the worm gear drives rotation of the worm wheel, rotation of the worm wheel simultaneously moves the top plate vertically relative to the core, and movement of the top plate adjusts the ride height of the vehicle in a corresponding direction,
wherein the top plate includes an aperture that is aligned with the worm gear; and
a set screw positioned within the aperture and configured to restrict rotation of the worm gear.
