Spend the time to find the source of your problems, usually a new/better shop will be the solution and save you $$$.

BTW, the Eaton is silent. So any noise you have is with a bad gear setup. Again, that is an installer issue. Find a better shop.

And the SLP take off rears are about 50% weaker than than the Eaton. Please review your info and post a revised assessment with more detail. Thanks!

Dude I dont know where you have been hiding for the past 20 years but the 10 bolt Rear ends are junk!! If you are making over 200hp and run your car at the track then it is just a matter of time. I broke a Stock 3.23 gear rear end with my V6 on motor!! My car put out 186 rwhp on motor at the time. Setup has alot to do with it but also how you drive your car. My Built rear end saw a couple of nitrous dumps at 5grand with some DR's. My car was putting 430 tq through the rear.

The rear end I broke on my WS6 was the bone stock 3.42 rear end. My car made 325rwhp at the time and I broke it cutting a 2.1 60' at the track on street tires!! Not even DR's.

In my V6 I had a 3.23 rear that was bone stock that broke at the track, I had a 3.73 ZT LS1 rear end that broke on the street, and my Eaton 4.10 rear that didnt break on me but broke on my friends car at the autocross track and it was the Diff that broke. On my 02 T/A My bone stock 3.42 rear broke at the track. I dont care if I break a rear end or not anymore because I have a warrenty on my T/A. Cost me 100.00 to get a brand new rear from GM!!

The bottom line is 10 bolts are junk. I wasted over 2000.00 on moding and buying other 10 bolts in the past on my V6 Firebird that All I should have done was save up and get a 12 bolt and be done with it!! I was nieve ( spell check) and thought I could build a solid 10 bolt that would last. I think I saw a artical in GM High tech on a 10 bolt in a 3rd gen with the car making 500rwhp or something. I thought if he could do so could I. Thats the joys of being young.

If you plan on running your car at the track and make over 200hp then you should save up for a 12 bolt rear end. It will save lots of time and frustration in the future and in the long run be one of the best mods you can do to your car.

I think that number is probably more like 1,000's of 3rd and 4th gen F-body owners.
