Abstract: A modular roof rack system which attaches to a vehicles body and/or frame which can either lay flat spanning the vehicle's roof or be extended vertically to accommodate luggage. When not expanded the vehicle will maintain a lower overall height facilitating the ability to be parked in garages, parking structures, as well as emitting less noise while the vehicle is in motion. When the rack needs to be expanded a cam tension bolt on each corner of the rack will be loosened allowing the inner portion of the rack to pivotally extend vertically. Once the rack is deployed said cam tension bolts will be tightened securing the now expanded rack into a deployed position.
