Cam and gears question

[ddoyle00]

Which aftermarket cam will work with a WJ 4.0?
Also, if my rear gears are moved up to 3.73 , its a good idea to upgrade the front also right?

you have to change the front and rear ratios at the same time, it will ruin your transfer case otherwise. pretty much any cam company will make a gear to fit the motor, you might not see it in a catalog so you might have to give them a jingle.
