I need a locker

[Bigg_Time]

Hey guys,

 

My Sierra is 2wd and has 9.5" 12 bolt rear end. I'm going to re-gear to compensate for the 35's, and I want to add a locker out back to help when I'm towing a trailer out in the desert, but as far as I can tell, no one makes any type of locker for this rear end. Am I missing something somewhere?

Does it have to be a locking style diff, or will another style work that directs power to both wheels?

Have you had this installed? With the ring gear spacer?

It looks like that truetrac unit is for a 14 bolt but the spacer is an adapter plate almost. So would the stock diff cover fit on it? Anyone have experience with this?

I was thinking about the Truetrac unit. Had one in my last truck and it worked well. Doesn't lock the rear wheels together, but rather uses a clever design to direct power to the wheel with the most traction.

This guys got the same question read though this one

so far all he’s found is you have to do the factory G80 with the 9.5 rear. 

The link in this thread has pics if that helps you out any.

Nope, dont have it.   Googled 12 bolt 9.5 locker and that came up.

In case anyone is searching, 

I contacted east coast gear supply got some clarification, they sell a Detroit truetrac for the 9.5 12 bolt, but it is in reality the same truetrac that fits into the 9.5" 14 bolts, just with a ring spacer that they sell to adapt it to the 12 bolt

The lack of aftermarket support for the 9.5" 12 bolt is a bit astonishing, it's been out for 5 years now.  The lack of discussion of this axles existence on this forum is equally astonishing.
