I'm planning to replace my rear diff and trans and wanted some advise.

For the rear diff what is best.....GM 12 bolt or a 12 bolt fromMoser, Strange etc?

For the trans I want to go with TH400 but do I buy a unit from GM or go with a unit from TCI or B & M, etc?

I want what is the strongest and will hold up in the long haul.

Thanks!

 

I think any 12 bolt will be about the same,

Check out summitracing.com they sell complete kits i belive.

As for a tranny, what engine you running?

 

I plan to install a ZZ572 crate motor if it will fit so about 620hp with TH400.

Any reco on TH400......GM or TCI or B & M?

Thanks!
