Abstract: A tip down vehicle top carrier having a removable base frame attached to the top of a vehicle. Attached to the base frame in a sliding relationship is a roller platform. Secured to the roller platform are various carrier devices such as a luggage box, ski rack, bike rack, tool box, or specialty equipment racks. The roller platform holding the cargo will not tip down until the platform is fully extended because of the configuration of the pivot wheels (breakover point) and the torsion spring axle. Once the roller platform is fully extended with a full load, it will gradually tip down as it increases the torque resistance of the torsion springs. If the roller platform is empty the user pulls it down using their own weight which "loads up" the torsion springs.
