Re-gearing to 4.88

07-11 six speed and 35s, you want 4.56s if your rug is light and you live in sea level flatlands, 4.88s if your rig is heavy or you live at higher elevations with hills and mountains, or 5.13s if you don't spend much time over 65 mph or both have a heavy rig and live at high elevation with mountains.
Since you live in Colorado Springs and have an 11 automatic 4dr JK, anything other than 5.38s would be a complete waste of money.

I also re geared my 2013 Sahara Unlimited with Yukon, and i am running 35" tires with a Bully Dog GT Tuner.
However the shifting of the gears are horrible in the sense that the car will not shift from 3rd to 4th gear unless i am on the red line and doing 110 miles an hour.
It just docent sound and feel good the shifting points.
However if driving it really slow the gears seem to have good shifting points.
When driving normally i can never get to 5th gear, i have to let go of the accelerator and then after pressing it again it will shift.
Anyone has experienced this?
I have ordered a ProCal from AEV to see if it makes a difference.

I also have the flashpaq but i noticed it hunts for the right gear about 2% of the time i drive. Could be the shitbox 4 speed auto too. Just never noticed that with my procal
