Gearing

Ok... so... I have a 98 Jeep Wrangler. I just bought my RC 3.25 Lift. Looking to put on 33's. My Jeep only has the 2.5 tho... Sooo I'm re-gearing to 4.88s to assist with the "lack of power" feeling. I know I need to change the front and rear gears, but I'm sort of new to all of this, and my question is.... I'm guessing this re-gear is just a "final drive" sort of thing, and I don't have to change 1st-5th gears as well? And if I do re-gear, do I need to change out the axles to be able to accept it as well?
And anybody know anything about these "super-chips" that guarantee more HP and MPGs at the same time? And what would you recomend?

Super chips = no go. Those don't work on TJ's. save your money.

And yes all you need to do is change the gears in the axles. And the stock axle shafts and carriers are fine as long as you stay 33's or smaller

x2. Those chips are such a waste of money, just like those cold air intakes... etc. Regear it and you'll get that pep you want. Then take that coin you saved by not buying that chip and put it towards some armor

When I search for the 4.88 gears, they come up with the same looking parts for both the front and the rear end... Do I just order 2 of the same things? I apologize for being so numb lol. Just a ton of questions and I'm not sure what I'm doing lol. I'd like to build all of this myself, so all of the help is soooo much appreciated.

Also, How do I know what type of rear end I have and does it matter what part I buy? Like, if I buy a Dana 35 4.88 gear, will that work in my stock carrier? Or if I buy a M35 4.88 gear will that work? So basically, do I need to know what type of rear end I have to be able to buy the gears to put in it? Sorry...

Your front & rear axles are two different types & they need their own unique parts. Your front axle is a Dana 30 & your rear axle is a Dana 35c. Ring & pinion installations are super-critical so far as proper gear setup is concerned so if you don't have experience setting them up, I would pay to have it done. I have a very well equipped garage, air tools, welder, etc. and install nearly everything myself but I pay others to install my gears.

I dunno what I would install first, R&P gears or tires, since either will have a dramatic effect on engine RPMs. I'd probably save up a little longer to install them within a few days of each other.

Thanks Jerry! So, does that mean that I need to only buy Dana gears to go in my Dana front and rear ends?

Yep, but I would simply specify to the shop you want Dana-Spicer gears & have them provide them.

Providing parts to the installing shop can open up a huge can of worms if something goes wrong during or after the install. And trust me, things can and do go wrong. The first regearing I had done lasted six weeks before they started howling from an improper installation. Fortunately their warranty covered all parts and labor for the repair since they provided all the parts too.

Otherwise the shop can just blame your parts & leave it up to you to get any bad parts replaced under warranty. The parts dealer will then blame the installer who is actually usually the one at fault. Then the installer may want to charge you for labor again if you are able to get new replacement parts under warranty since, remember, he blamed the parts & not his labor.

Besides, most shops will discount the parts if you push/ask them to to a cost that will be competitive enough with an online source. Their main profit is on the labor, not so much the parts.
