Would changing my gearing effect my 4x4 system. Would the rear be going faster then the front or could I just add the 4.1 and it will all be fine?

 

you have to put the same gears in the front and rear when you do a gear change. if you dont you will destroy your transfer case.

 

Yep, Yep, Yep. Listen to scotty here.

You can change both ends though. It will have a profound effect on your performance if you are or are intending to run over-size tires / wheels.

 

I've heard of guys disabling their 4x4 system so that they can install gearing on a piecemeal basis. Do the rearend first then the front when you can afford. Don't know what the disabling process entails, but I'd assume with all of the electronics, it wouldn't be too much more than a fuse or switch????
