Should I swap my transfer case?

I got my eye on a 2005 NV241 Rubicon trasfer case that I want to swap in for my old 1997 NV231.

I want to know what will be the endresult of this swap, having 35" tires, AX-15 tranny and 4.88 gears ?

I know the ratio is 4:1 vs 2.72:1.. but can some one explain this better for me please

any inputs on how easy is the install will be?

thanks

You will have a lower 4lo, meaning your engine will turn the tires more while using less power.

That transfer case also has a fixed yoke output, as opposed to your stock slip yoke, allowing you to use a double cardan rear drive shaft. So you will need a new rear driveshaft as well as adjustable upper control arms for the rear. I believe the front shaft remains the same.

Thanks for the fast reply JCWJEEP...
So besically if I do swap in the NV241 transfer cases, this will be a good set up since I have a mamual tranny and it will help me avoit stalling the Jeep up hills since I will be using less power from the motor right?

Can I modidy my stock rear drive shaft to be used with the NV241 trafers?


any more inputs are walcome. please let me know if I am missing any info in the future swap...

In low range, yes. In high range, no.

The only change is present in 4lo. On road driving, I think, is exactly much the same.

No, you will need to buy a new driveshaft.

For your experts out there, do you guys recommend this mod?
