Im looking fora whole rear axle for just a quick swap. 3.92 posi. If you would like to trade for my 3.55s for better mpg please let me know. Otherwise, $ is the name of the game.

 

bump
?

 

I would stay away from the factory posi unit, especially if your gonna be looking for reliability at the track. To be honest, they flat out suck

Some 3.92s or 4.10 and a new posi unit shouldn't be over $500

 

i don't think they came with posi's if you chosed the 3.92 option

 

i with socha on this one. if it was me, id get a good ls. my first choise if you really gunna race it would be a detroit truetrac. and def go for 4.10's if you like taking it to the track/street driving

 

i dont want a locker, it is a daily driver remember. 410s is a nice upgrade from 355s for now, but 392s would be the best bet when all things are considered. Mileage, wear and tear, final drive ratio whenever it is that i get a set of rims and drs., and also 410swill be too steep of a gear for racing out of overdrive (eventually that wont be a problem, but for now it is.) As far as posi units go, i agree that the factory one isnt as good as aftermarket ones, but its better than not having one.

they did. theres one on an sst thats for sale that my buddy is consistantly bugging me to go down to one night and trade axles while no one can see lol.

 

the truetrac isnt a locker. its a gear driven limited slip. its alittle harsher then a clutch style ls but alot stronger ( harsher meaning its gunna give ya traction no matter what, theres not gunna be much slippage)

intreguing....so whats the big diffrence, no clutches?

 

yea theres no clutches at all. ive personally never heard anything bad about them. i was consitering getting one for my front axle

 

sounds like from the quick reading on google and whatnot iv just done that they flip flop torque, so its like having an open that jumps from wheel to wheel....or so it sounds.
