I should know the answer to this, but I do not. Will a fast ratio pitman arm be of any benefit in my Valiant, even though it has the standard steering box? @72bluNblu?
By standard you mean just the regular old 16:1 power steering box right?
On the AAR’s they were used to change the 16:1 power steering boxes to an effective 12:1 ratio. The AAR steering boxes weren’t that different, they had the same ratio as the standard power steering box but if I recall correctly the internal stops were changed because of how the longer pitman changes the throw.
On a standard power steering box they still give the same effective ratio, 12:1.
If you’re talking about a 24:1 manual box, I think you’d end up at 18:1? It’s a percentage change on the lever arm, not a straight 4:1 reduction. So on a 16:1 box it’s a 25% reduction, it should be the same percent reduction regardless of the ration of the box.
