Gears and axels

I'm looking at putting some new gears on my jeep and need some help! first i don't really know if i have the D30 or D35 axle... Does anybody know. I got a 06 4cyl and i have a 4" with 33x12.50 on and want to go to a 4.88.
The second part of my question is does anybody know how good Alloy USA is for a ring and pinion set. Or should i just stick with Superior?
Thanks

Alloy USA is a great brand as well, as for the axle you have a D30 in the front but in the back you have the D35

i have alloy gears and axle shafts and they work fine.

if you have enough money, think about installing some lockers at the same time. you´ll need nearly the same time for installing lockers and gears or only the gears.

take a look at your rear axle. is it really a D35? i know that european 4cyl and 6cyl TJs same with a rear D44 since 2004.

All US model TJs with the 2.5L engine come with the Dana 35c rear axle, with a Dana 30 front axle. Alloy USA makes great products, I would trust their R&P gears in a heartbeat.

If you're not installing your own gears, do not buy the gears & install kits yourself and give them to the installer. If you do and something goes wrong during or after the installation, you're up **** creek without a paddle. The installer will blame the parts you gave him and it will be up to you to get them replaced under warranty. And odds are the dealer you bought the parts from would balk at replacing them under warranty as they would just blame the installer (who usually is the reason for a problem). So there you are, the installer and the parts provider are pointing fingers at each other and you're stuck in the middle. Even if you get the parts replaced under warranty, you will have to pay the installer AGAIN to install the parts.

If the installer provides the parts, his warranty will cover parts and labor and you won't be left holding the bag if something goes wrong. And things do go wrong on occasion, my last R&P installation didn't go right. Two weeks after the new gears were installed, the new rear gears went bad and the shop took care of everything no questions asked.
