I bought a 2003 Silverado and decided to buy a Detroit TruTrac for it because I was having serious traction problems at the track. I did 18 sec in the 1/4 spinning the whole way, lol. DR's helped a lot(13.9 1/4) but still some wheel spin so I can't hammer it.

Any ways, I went online and ordered a DTT for the Chevy 8.5/8.6 10 bolt assuming that is what I had since they come standard on the Silverado. Problem is my truck is a foreign(Mexico) model so it has a different rear end(Latin rear ohh great now I am thinking Vida Guerra). The shop that was going to install the DTT told me that I did not have a 10 bolt but a Dana. They were not sure exactly which one only that it was smaller than the 60. I ended up selling the DTT to a member here.

I looked online and it looks like a Dana 44. I went to another shop and they said it looked like a Dana Super 44 and in order to get a Posi in there I would need a c-clip eliminator and a bunch of other stuff. It would cost about $1600-1800.

Can anyone here tell me what rear end I have? And if I can get some sort of Posi in it?

Here are some pics.

 

that dont look like vida guerra at all... lmao!

 

jus look in summit match up the bolt pattern in the richmond gear sec.

 

I did that(except using a 4x4 shop online) and I came up with a Dana 44. But the shop thinks it's a Dana Super 44. They look the same from the outside.

 

Why not try and find a used 10 bolt and swap it in? Seems like it would be a much cheaper route. I sold my perfectly working 10 bolt complete from caliper to caliper for $250

 

Don't want to get too racey but here you go, lol.







Enjoy!!

 

The Dana in it now is supposed to be sturdier than the 10 bolt. If I can't find a Posi for it then I will probably go to the 14 bolt instead since people have been breaking the 10 bolt. I am trying to avoid than do to the expense of buying the diff then adding the Posi plus if it does not have the same gears then I would have to swap them also. Looking for the cheapest solution possible but while still getting what I want(Posi).

 

There are guys running solid 10s on a 10 bolt with just a true trac. I'm not sure what your plans are, but most people will never see those numbers.

 

I wonder how much power vida's rear will hold?
