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.

To set up the swap correctly you will need to be sure you have the specs to set it up by and the gauges. if you don't set the gears matched up the way they are worn in you will have a noisy rear end.

We swapped the axles between 2 3500 4X4 took the 4.10s out of the Diesel and 3.55s out of the V10. Both were 5spds and used for towing. It improved both trucks. After that I would never put 4.11s in a cummins. I have never had trouble getting started with a load even on a hill and we have grossed out over 22K.

I love the 4.11s 3.54s kill my mileage in this truck. If I'm grossing 20k and under no huge deal but 33k you are really feeling it, especially in the hills. Then again the most I have ever driven my truck without a trailer is the 150 miles home when I bought it.

We're flat landers so not used to pulling in the hills. I can't imagine a pickup truck would be heavy enough to give you good control with a 33K gross. Even with a 22K gross I didn't have any brakes by the time I got to the bottom of a grade in Tenn.

Steep grade with that much in one of our trucks is something I avoid. Electric over hydraulic on both axles helps everywhere else. Got more time than money start out slow.

i can buy a good used set of 3.54's carrier and all for 350 bucks he just wants to get rid of them im just not sure i want them idk 373's or 3.54's what should i do i plan on running 35's as well

You may want to figure your circumference of the 35's and compare with the stock tires. Then you can determine how much they will change your tire rotations per mile. I know a guy who changed tire size instead of changing gear ratio.
