Fast ratio pitman and idler arms

It's on a manual steering car. Sorry, my bad. Forget to include that important piece of information.

Do you know what ration you have now? 23 or 16 (approximate numbers)

Also do you know how much the arms decrease the ratio?

Also what width tire?

SB or BB?

I have 205s with a 23 to one manual steering, standard idlers, and I can palm steer at slow speeds but have to arm over arm if sitting still or going into a parking space. While driving there is now particular effort!

I imagine 16 to one would be about 30% more effort.

The fast ratio pitman and idler arms are meant for power steering boxes, although they can be used with manual boxes. The power steering boxes have a 16:1 ratio normally, with the fast ratio arms the effective ratio becomes ~12:1.

So, I don’t see any reason to use them with a manual box. The standard ratio manual steering box is 24:1, the fast ratio arms would basically make it a 16:1 ratio. But, you can just buy a fast ratio manual steering box that already has a 16:1 ratio, without adding any clearance issues. As for using the fast ratio arms on a 16:1 manual box, I don’t think that would be a good idea. The resulting 12:1 ratio would make the car very difficult to steer at low speeds. I run a 16:1 fast ratio manual box, and while I like it and don’t have any plans to change it, I don’t think a 12:1 manual box would be workable for most folks.
