4.11's to 3.54's
 

if im going to 3.54's from my 4.11's will i need to change the carrier or can i use the the stock 4.11 one?

Can't answer that think they're the same just wish you lived closer for a trade I want 4.11s for towing since that's about all my truck is used for. NM too far.

damnit lol i would do it in heart beat lol but thank you i think they are the same im almost positive but i really wanna be sure ya know lol no sence in waisting money

I would trade also, my truck isn't a daily driver. When I do drive it, it usually has a trailer hooked to it. My suggestion is to ask the people where your getting the gear sets from. Some manufacturers will make the ring gear thicker so to be able to use whatever your carrier is. I have had to use a spacer ring for a 10 bolt gm rear I was setting up. Went from 2.73 to 3.73.

no both ring and pinions are same year dodge cummins same rears and stock as well just one is a 3.55 and the other is 4.10

Ok so you got a set of used gears from another truck. To bad you just can't swap carriers over as well. Then problem would be solved. I used to know the limitations of gear differences on what carriers but for the life of me can not remember them. I have an idea though, give richmond gear a shout. Ask questions like your gunna buy a set of gears. They'll will tell you if you need a ring gear spacer or not. I'm thinking you don't need a spacer though. But it always good to be safe.

ya thats a good idea hmm ill do that thanks alot didnt even cross my mind ya i wanna have everything i need i dont have time for down time lol

Everything needs to be swapped over carrier and all. Also need to throw in new thrust washers,set up backlash ect. My buddy and I swapped over axles cause it was much easier. Took us a few hours but werent really in a hurry.

were they stock to stock gears though not like yukon or usa gears?

Both axles had stock gears swapping them over would still require to set them up right.
