4.10 to 3.54 questions
 

So I'm trading gears from a 4.10 to what I'm told is a 3.55. That is all fine and dandy but if they come to me and they're 3.54, I heard that it won't match right with the pinion.

You'll need the ring and pinion.

you can use a different ring and pinion but idk how long it will last and it will howl like a bitch, they are matched to each other, ring and pinion come and go together

dodge is 354 ratio not 355
354 is as big that will fit in the case
