i wana make sure that i wont snap an axle with this car
camed car about 415 hp and a posible 150 dry shot

i am going to buy a 12 bolt and i know that most of the reson why they brake is the crap clutch style posies that they make for them

i want something stronger but dont want a locker that is going to make all that noice so im looking into the powertrax locker
it is a true locker but does not make the noice of a traditional locker but the problem is they only make up to 30 spline for 12 bolts


will the 30 spline be enough?

thanks alot

trac-tech (detroit locker manufacturer) makes a 33 spline diff for the 12-bolt (gear driven).

If you go with the 30 spline moroso makes a clutch types posi that LOOKS to be a little more beeffier than the Eaton

i dont want to use 30 spline if i dont have to

the trac-tech looks good but its a posi like the ones that come stock in are 10 bolts but probably much stronger

the reason i like the powertrax is that it is a true locker but its quite

If you race a lot I would go with 33's.

most of the time people dont break the axles, its the gears or the pos. traction unit.

You should be fine but I would get the 33s just for extra insurance. If your worried about weight, go with 35 gundrilled. They are a little heavier then 30 splines.

That's great advice man, except for the fact that he's asking about a posi or locker diff and you can't get anything 'cept a spool for 35 spline axles.

Correction....you can get a locker for a 35 spline axle. Not a posi though.

i plan on getting a strange rear and i just saw on another thread that the detroit softlocker"tractech" oly works for moser 33 spline axles and the strange have the worng angle on the teeth of the axles

is that true any one know

I didn't think they had 35 spline axles for the 12 bolt, thought that was 9" only?

Im not sure I have a 9" and a spool
