Abstract
A rack extension device for use with an existing rack and pinion steering system and a suspension lift system. The rack extension device includes a second rack disposed beneath the original rack and adapted to receive the tie rods of the rack and pinion steering system so that the tie rods maintain their original geometry when the original rack is elevated. The present invention also includes a method for adapting a rack and pinion steering system having an original rack and tie rods for use with a suspension lift system. The method includes the steps of providing a second rack adapted to receive the tie rods, and mounting the second rack below the original rack so that the tie rods maintain their original geometry when the original rack is elevated by the suspension lift system.
