I've got a stock posi 2.73 rear from a 98 camaro. I'm going to have 3.73 gears put in it. I know they make 3.73 gears that work on a 2 series carrier. Using this setup is there any strength sacrifice? I'm going to be running about 400lbft into this through a t-56. Would I be better of to get a take off posi from slp (these come with 3-series carrier, right) and get normal 3.73 gears? How good is this take-off posi, is it the same thing I have in the rear end now? Keep in mind the take off posi is $100 and the gears for the 2-series carrier are like $15 extra.

 

Personaly, I think you'd be better off using the 2 series and the thicker gear. Less chance of breaking. Don't go with a spacer though. I ran a 69 camaro back in the early 70s with a spacer in my 12 bolt, [513 in a 3 series] carier. Kept breaking the bolts. But then again I was running a .030 350, rockcrusher that ran7.30- 7.40s in the 1/8.

 

where do you get those gears at? Only $100 for the posi where can i get posi for 100 at?

 

The posi is from SLP, I'm not sure of their website... its a new take out from the cars they modifiy. The gears for 3 series gears in a 2 sereis carrier ar available from most of the big gear manufacturers... summit carries richmond and they make them... a set is around $200.

As for my question, I'm actually leaning toward getting the take off posi and some uses 373 gears. Can anyone shed some light on how this take out posi from SLP differs from the stock posi in my rear end which is from a 98 camaro, 273 gears.

 

When SLP builds up the Camaros, they install a stronger posi to handle more power. The 99 dollar one is the old weaker one. I would just use the 2 series 3.73's. I've had them for about 5 years now.

 

is there anything different i have to do to install the 2 series 3:73?

 

No, nothing special. They are simply a little bit thicker is all.
