A friend called me and asked how to find the ratio in his 14 bolt rear end and I recalled that I devided the two numbers that were on the ring gear to get my ratio of 4.10 in my 14 bolt. The two numbers he gave me were 45 and 14. I cant remember my numbers to compare them, do those numbers sound right for the amount of ring and pinion teeth? Dividing the two numbers comes to something like 3.2....., which didnt make sense to me because I thought it was supposed to come out as a 3 digit number first of all, and second of all, I didnt think a 14 bolt rear end came with any higher gears than 3.73. The gears arent as low as mine, so I assumed they were 3.73. Were there ever any other ratio's in 14 bolt FF rear ends? Or are those numbers he gave me wrong and its probly just 3.73? I think he said he counted the teeth on the ring gear and came out with 45 so I assumed that at least that number was right. Maybe the pinion teeth number was wrong?
