I'm going to swap out my 2.73's for either 3.42 or 3.73's.I know I can buy those gears for a 2 series carrier but I found a 3 series carrier on RockAuto for $150. So what I want to know, are their any benifits to having a 3 series carrier compared to a 2 series? Also, if I go to a 3 series carrier then I'd have to get a 4 channel carrier to keep traction control right?

I can't answer your question, but I would be interested in your 2-series carrier if it is torsen.

Well it's whatever the stock brand that GM put on and I have no clue what that is. But if I do end up going with a 3 series then I'd be happy to sell it to you.

Get the 3 series carrier. I had the same as you. I got 3.73 Motive gears for my 2 series. It worked fine but the noise they make is terrible. Sounds like a jet engine inside the car. I was told to get a OEM torsen 3 series and gears and it would be better on the ears. I got a set but have not put them in yet. Also, if you have a steel drive shaft you will have to replace it with an aluminum drive shaft. I do not have traction control but was told they are interchangable to any of the carriers.

How much did you get your torsen carrier for?

I got the carrier and gears for $202.50 off ebay.

I would keep the series 2 and get the appropriate gears. If you get a series 3 carrier you will also need a 3 series and ring if your car doesn't have tcs.

Also @wma if your gears are that loud it's either defective gears or more likely they were installed wrong. Being a thick cut or thin cut series 3 won't change the noise.

To the op keep your series 2 and pick up a set of the blue box motive or yukon 3.42s made for a series 2. You'll gain a little strength with the thicker gear and also save some money. The blue box motive or yukon will be the quietest you can get that's not stock

According to Jeg's, Motive Gears do not make a 3.42 ring and pinion for a 2 series in the blue box.

I have to agree here. That is what I did - went from 2.73 to 3.42 with Motive gears for 2 series carrier and it worked great. I did the setup myself and it runs pretty quiet. With 3.73 gears, now, if you have zexel torsen, the paddle will not go back in without grinding something.

Is it really hard to change the rear end ratio myself? My dad builds engines and trannys, but he told me that he had never tried the rear ends, and he knows that he would need some special tools. So, is it really hard? My rear end is 2.73, but because we live in Russia shipping would be a killer deal. About 800$ for the rear end, if i buy it for 350

Building a 10 Bolt is a waste of time and money. Save up and get a used 9in or 12 bolt. It will be well worth the wait to be able to dump it from red line any time you want.

Rebuilding a 10 bolt is tricky, but doable for someone with considerable mechanical experience. Not for the average do-it-yourselfer. If you have access to a hydraulic press, your dad could probably handle it. As far as rebuilding a 10 bolt being a waste of time as mentioned above, you will get that opinion alot, and I do not agree and here is why. That is true for drag racers who like doing 4,000 rpm drag launches all the time, more so with a 6 speed than with an automatic. For a daily driver occasionally driven hard, the 10 bolt will last. Going to the track all the time, have a trailer handy. Also, if you do not need the strength repeated high rpm drag launches demand, you are losing power at the wheels with a 9" or a 12 bolt. That's the only redeeming characteristic of the 10 bolt - less rotating mass.

i stand corrected. if you are planning to drive your car like a economy car with the ocational launch then you will be fine with a 10 bolt. however if you like to raise hell like i do and visit the strip, autoX, and Road course then a 9 inch is beneficial. you dot have to worry about it breaking every time you do something. my buddy has a cam only ws6 and he has went through 4 10 bolts in just over 6 months. yes you lose power in a 9 in or 10 bolt but for the money, ease of gear change and cost i think it is the est way to go. a 9 in gear swap will take a hour vs all day with a 10 bolt
