WK 3.7 gearing

hi, i have a grand cherokee 2006 3.6 4x4 all the time, the thing is that it has 20 inch rims and i want to change the gearing from 3.07 to 4.11,
do i have to change the front and rear rings and pinions? and if yes does it have to be the same size the rear as the front?

re: WK 3.7 gearing

Nobody makes 4.11 gears for the front end of our WKs. The best you could do is swap in a hemi front axle with stock 3.73's and regear the rear to match
