What's the tire size that you have ?
This will play a role to choose the ratio.
We sell a lot of the truetrac and the Yukon Duragrip for the GM 8.5/8.6 application.They are holding just fine for big tires and street/strip abuse.
Any time you change the ring & pinion,a master install kit is the way to go to install them right.
Maybe I should start advertising here for differential parts even though I'm in Canada,we can drop ship from 3 US warehouses to your door .
