Steering box question
I recently replaced my steering box with one from A1 Cardone and I don't think it is the correct quick ratio box. It feels a bit sluggish to respond to my inputs, but it doesn't leak and has no slop it in. How would I tell for sure if it is the quick ratio or not? I'm thinking of marking how much I turn the steering wheel compared to how much the pitman arm rotates. But what would I look for?
From what I understand there are 2 ratios, 12:1 (quick ratio) and 14:1. With the 12:1 I would turn the steering wheel 12* and the pitman arm should turn 1*. This isn't all that easy to measure so does anyone have a suggestion?
I know the whole 2-3/4 turn vs. 2-1/4, but that has to do with the internal stops in the box and not necessarily the ratio. FYI it is about 2-3/4.

The turns have everything to do with it. If you originally had a 2.25 turn box and now you don't, well, you got junk. I ran into this problem when I went shopping for a new box.
I dare anyone to explain how two boxes, with equal travel, one box is 2.25 turns (lock to lock) and the other is 2.75 turns, how the one with more turns can have a quicker turning ratio than the one with less? It can't!!!
This thread has some useful information.

The link you posted isn't working, so I found this one.
https://www.thirdgen.org/techbb2/sho...internal+stops
Actually you posted in it too and if you read what MrDude_1 writes. "how many turns LOCK to LOCK is how much you can turn the wheel until the stops in the box keep you from turning it more. "
So the internal stops are what set the lock to lock, not the ratio. My question is... How can I tell if it is the slow ratio? Something tells me the stamping on the box itself doesn't mean much since it can be stuffed full of any ratio. Short of pulling the box apart and counting the teeth I'm thinking I would have to set up some kind of protractor and mark how many degrees everything turns. I was just asking if anyone has done it this way, a 2* difference can be hard to tell.
I read that a while ago too, and came to the conclusion that a factory rebuilt box is what I wanted since the Lee is too pricey for rightt now. More than double actually.

Well, you found the link I was trying to supply you. Cool.
Look, what I'm trying to say is #1 I am fairly certain the box you have is not the quick ratio box. #2 Yes, the stops are in the box to keep the wheels from turning forever. However, as I stated in the thread all the boxes had the same range of travel from lock to lock. Lets say that the range of travel was 100'. Whether it was 2.25/2.5/2.75 or 3.0, they all had the same travel. So, If you had to make an assumption, which would you think was a faster box? Wouldn't it make sense that a quicker ratio box would make fewer turns than a slower ratio with in the same travel range?? I spent a lot of time trying to get the right box on my car. I have had several types, several ratios. There is no physical way a quicker ratio box takes more turns to go lock to lock, within the same travel range. And, that's the most important point(The same travel range).
Good luck. Peace Brother.
