My XJ came stock with 3.55 gears front and rear from the factory.It was equipped with 205/75/r15 tires.

My XJ now has the same stock gears but has 32x11.50x15 tires. It's a dog getting off the line,but once up to speed things are ok.

I would like to run a 4.10 in the front and a 4.11 in the rear. How much of a difference will I notice in performance and MPG (off road,climbing/crawling,daily driving on the street) with the new gears and tires that are currently on it?

i think you need the same gear ratio front and rear?

but my friend has 4.10's in his yj with 32's and its a good balance

that much of a difference is fine, my buddy has a stock d44 rear and the front is 3.55 and the rear is 3.54 a hundredth off wont cause any damage

As far as I know its common to have a 4.10 front and a 4.11 rear. This is how my parts XJ is equipped from the factory and that's where I'm planning on getting the gears from.
