By moving the outer tie rod end to the underside of the spindle arm, the tie rod sits at a more favorable angle for lowered cars. This item eliminates body modification required for tie rod clearance. Don't take a chance on bending your tie rods on the first big bump in the road! Also improves bump steer effect and stability. Fits 71 to 73 lowered Super models. Requires a drill press, and 5/8 inch drill for installation. Spindles must be removed from car for drilling for best results.
