A totally redesigned version of NRG quick release systems, this quick release kit utilizes a pin and gear locking mechanism for maximum durability, no play, and all the while reducing required space. In fact, this reduces the height of our quick release systems by over half from a 3 inches height to a mere 1.25 inches. Perfect for those individuals who feel the need to put their steering wheels further away from their bodies, or for those who have the necessity to use a crush-type hub. *** Not Compatible with NRG Short Hub Adapter or Quick Lock ***
