Abstract: The present invention is a modified ball joint assembly for attachment to a steering knuckle made up of a body and a spacer. The body includes a ball joint at one end, a set of attachment openings at the other end, and a variably spaced segment between the ends. The spacer inserts into a void in the lower control arm of the vehicle, and includes a plurality of complementary attachment openings for use in attaching the body and the spacer to the lower control arm. The modified ball joint assembly lowers the position of the lower control arm of the vehicle relative to the steering knuckle thereby lowering the ride height of a vehicle a desired amount without requiring the removal of or modification of the steering knuckle. The present invention allows the factory-supplied steering knuckle and tires to be used, providing a considerable cost savings to the end user.
