5.13 gears in 14 bolt/what gears do i have

i got a set of 5.13s for my 14 bolt but its the thicker ring gear because i belive i have 410 or numerical lower. i just wanted to make sure i had the right gears. Because when i got my new 5.13 i counted the teeth on ring and pinion and divided them and got something like 5.125. But when i counted the ring and pinion on my gears i have installed now i was comming up with 3.21 or something. I have put it back together sine then but i do remember the pinion on the gear i have in now had 14 teeth. please help im confused iv heard or 410 and 373 in 14 bolts but never anything like 321s am i doing something wrong.

My dad's 98' 3/4 ton came with high gears, I think they were like 3.54s or something close to that. So yes they could be that high.

They do make 3.21's for a 14 bolt FF and it seems like I heard that the carrier is different for that one ratio. I could be wrong as I've never first hand touched a set but I'd check with whomever you bought the 5.13's from, they should be able to tell you.

look on the edge of your old ring gear and there are 2 numbers like 41 10 or something like that. Divide the first by the second and that will tell you the ratio. There is a carrier change from 4.10 to 4.56 so if 4.10 or less need thick gears or new carrier.

I have a 14 bolt SF with 3.42 gears.........could I swap in 4.10's without changing the carrier?
