What would happen if i put 4.10s on a mostly stock cherokee?

I think you would just have more torque, but youd have to drive it respectfully, since the d30 will probably break

It will explode and kill a bunch of Nuns and orphans.

From your vehicle specs, I assume you have a 3.55 now.

It will accelerate as if you gained 15% more horsepower, but you will be turning more rpms at highway speed and your mileage will suffer.

Going to 4.10's alone will not destroy either diff...I wouln't worry about that.

I always felt that the 4.0L with 3.55's was a decent gear with stock tires. It was peppy enough and rpms were in the powerband on the highway. It was when I went with bigger tires that gearing lower really helped. I have 31's now and 4.10's are a nice gear for the tire size.

i have stock gears on my xj (3.07) and i was going to put 31's on. i was wondering if that will lessen my torqure and give me more top end on the highway.

itsanxjthing

Yes it will. Not by much will you notice the top end, You will use more fuel

3.07's with 31's suck. I did it for a year. I went with 3.73's and its about perfect for the size of tire/type of driving I do. Wanna talk about bad a friend is running 33's with 3.07's I drove his jeep home the other day and it took forever just to get moving and up to speed.

on a Dana35 with how puny the ring gear is...4.10s behind a 4.0 gives you a MUCH better change of destroying the rear diff.

I checked his profile before responding. He has the Chrysler 8.25...not the Dana 35.

Even still, 4.10's on stock tires would still not kill a Turdy5. Besides, he said his Jeep is stock. It would be different if he said he wants 4.56 gears and is going to install 33's and a locker.

4.10's are a nice compromise on ratio. You can put a set of 30/31's on it and have decent power, and ok fuel economy as long as you drive sanely.

As for the D35. I can attest to the strength of them. I ran one when I first got into wheeling with 33's Here is a pic of me ON slick Rock In Tellico giving it hell.



Didnt break anything

4.3L XJ

The simple fact is that if you do that, you will have the stock gears for the four cylinder engine. No you won't hurt it, no it won't be weaker. You will turn a little over 3,000 rpms at 65 mph and will have lots more acceleration and torque. It is the perfect ratio if you want to go to 31s

ya i going 31s soon i guess ill wait till i get the 31s for the new gears.

ZachsXJ

You can get away with 31s on stock gears without much trouble. I'm running 31x10.50s on stock 3.07 gears and its not unbearable to drive, a bit sluggish in 5th below 70mph but thats about it

ya i not terribly worried about it just dreamin.
