Might be a dumb question, but I'm eye balling a detroit truetrac for my 79 c10.

It seems to be the only one that'll hold up to much power past 500hp, aside from a spool or a real deal detroit.
Matter of fact, research seems to suggest the truetrac will live up to 900hp. I'm not running a spool or a actual detroit.


Can maybe someone explain the differences here ? I must be missing something.

My truck 12 bolt is a 8.875 ring gear, 30 spline axles.

The Truetracs I put in my 10 bolt GM trucks have two sets of sprial cut spider gears. The Ford F750's we have at work have three sets of sprial cut gear Truetracs from the factory. Large differentials pushed by 6 cylinder Cat engines through a 6 speed Allison 3000 world trans.

The second link picture shows a cut-a-way of what looks like a 4 set of sprial gears. Something in a military truck

No problem. I have settled with true track as well for one of my vehicles. But it is behind a 200hp 305...

I believe I'll pass on a 14 bolt in the truck, BUT, I still am interested in the Detroit for my s10's 14 bolt.
