ABSTRACT:
An apparatus and assembly method including a sprocket hub and a locking collar for go kart vehicles and other land vehicles with drive axles is provided. The present invention eliminates the need for two locking collars on either side of the sprocket hub. The invention further provides a lightweight sprocket hub with a hub neck portion adapted to receive a single locking collar. The sprocket hub fits loosely on the drive axle. The fin-like sprocket hub arms and sprocket hub extensions each have sprocket connection holes used to connect the sprocket hub to a drive sprocket. The locking collar engages the sprocket hub neck portion by means of two flanges located on the sprocket hub. As assembled, the sprocket hub and locking collar float and oscillate on the drive axle to compensate for chassis flex and chain bind such that acceleration of said kart vehicle is enhanced.
