I own a 2000 NHRA Pontiac Firebird Trans Am LS1, recently the differential had been leaking and making a noise. Everyone I've had look at it tells me I need a new one. Where would be the best website to go to order one? I'm looking for 3.73 ratio or 4.10 ratio. I don't know the difference between higher or lower numerical carriers. I also don't know how many teeth to go with.

Are you wanting to stick with a 10 bolt or do you want something stronger? I have a 12 bolt that I love but a s60 with a spool would only set you back about 2k.

Can you give us a little more info on the car such as gear ratio whether is a 6spd or auto and what you do with it.

Here are the Moser 12 bolt and 9 inch rears that I sell. Give me a call if you have any questions, or send me an e-mail. Bob

I just recently bought the car so I'm still learning about it. Its a 6-Speed with a stage 2 clutch making roughly 400hp. I'm not sure on the torque. I would just like to have a nice ride with the ability to kick the *** end out if I want. Whatever I get I need to know its going to handle the torque and power.

Stay away from a 10 bolt then, unless your adding more hp to it in the future any of the 3 should do you fine. 12 bolt is probably a cheaper option. Don't get a spool, some of the less expensive rears come with spools that are tough as nails but not good on the street. Im not experienced with different setups but I love my strange 12 bolt.

I was thinking about this one http://www.jegs.com/i/Eaton/362/19599-010/10002/-1

I'm sure that would do great, should be pretty similar feel to stock. I went with this cause its supposed to take a beating and last forever, I like it but the posi might ride better.

I was told i need a posi locking diff. I'm just trying to find the best one

Doesn't have to be posi to be safe and good on the street. Watch this video to understand the benefits of a helical gear differential.

Here is a video of a posi.

Which differentials would you recommend for a 2000 Trans Am 6 Speed Manual with a stage 2 clutch making 400 rhp?

stevenc1703

What are you doing with the car? Drag racing, track racing, or daily driving?

Fresh gears, fresh bearings, good as new.

xxbiodavexx

Right now its just for daily driving. They are putting a drag strip close to my house next year, and I was thinking about testing my luck.

If your car has ABS and traction control, the Trac-Loc is a good way to go. You can't go with the Trac-Loc if you have just ABS, in which case I'd go with the Truetrac. Bob
