It's a direct swap and a wonderful cheap way to get 4.10's.

i have a 2006 4 cyl 6 speed, i was under the impression mine has 3.73 gears? was it just the older 5 speeds that had 4.10s???

I would not trade if you have a dana 44 rear. Other wise bolt in.

I'm not sure, I'm not even sure if this one has 4.10's I just wanted to know if it was a bolt in because I know with my Comanche to Cherokee it's pretty much a bolt in...

I have D35...

You would have to swap both. Both axles have to be geared the same.

That's my understanding. FWIW.

Multiply your rpms by 1.099 and thats what they will be at any given speed.

Yeah I know both axles. I'm beginning to work on my jeep and drive my 2.5l Comanche around so I want to get ready trails later on.

The early 4cyl 5spds got 4.10 the 03-06 or when they got the 2.4 got 4.56s with the auto that's the friggin unicorn of stock axles. The sixes got 3.07 and 3.73 and only in 97 3.55's were an option. Can't remember what all the autos got with a six.
