Gear recommendation for 4 cyl and 33 tires

Hello, I made some search but I am a little confused.

I bought a '02 TJ with 4 cylinders, 5 speed manual, it has 4.11 axles (D30 and D35), 31" tires and 3in lift. As you imagine the Jeep look not so nice with much space between the tire and the flare, so I'm planning to change those 31" for a 33" tires but I do not want to loose driveability (power and accel) considering that it's going to be my daily drive Jeep...

So, I am planning to upgrade the gear ratio to 4.56 or 4.88 but I still have doubts:

1. Whats better?.... 4.56 or 4.88?
2. Do I need to change carriers if I'm going to upgrade to any of these two options?


Thanks in advance...

Use the gear calculator link in my sig to figure out where you want to be. Others will offer info on the hardware.

you shouldn't need to change the carrier. Carrier break is at 3.73 IIRC

Definitely 4.88s and as others have said, you can re-use the stock carriers.

Oh, and in case you're still uncertain, go with the 4.88s
