How to Determine Steering Ratio

The overall ratio of a steering system is determined by the degree of the movement of the front wheels in relation to one turn of the pinion or steering wheel. Example: One turn of the steering wheel (360º) divided by 30º tire movement would have an overall ratio of 12 to 1 (360/30).

This overall ratio is determined with the distance of the rack travel created by one turn of the pinion and the length of the spindle arm that the tie rod connects to. A shorter steering arm will result in faster steering and the overall ratio smaller numerically. A longer arm will result in slower steering and the overall ratio larger numerically.

For reference purposes, the ratios that we list are calculated using a spindle arm length of 5 inches. This is the distance measured from the center of the spindle king pin axis to the center of the mounting hole for the tie rod.
