do?\u003c\/h2\u003e\n\u003cp\u003eInstead of replacing the steering column or steering plate, the extender bolts onto the existing steering arm and relocates the tie rod mounting hole.\u003c\/p\u003e\n\u003cp\u003eThis changes the \u003cstrong\u003eAckermann effect\u003c\/strong\u003e, which is the difference in steering angle between the inside and outside front
