diff. cover and tranny pan

[BigBusa]

Plan on ordering a Mag-Hytec differential cover and tranny pan soon but was wondering what size rear end is utlized in the 2006 5.9 because mag-hytec offers two:the AAM 10.5 and AAM 11.5 Also what are the viscosity ratings for the ATF and the rear-end gear oil in my truck? And does anyone have any suggestions/preferences?

I believe you have the AAM 11.5 in the rear and the AAM 9.25 in the front. The gear lube depends on your usage of the truck. Typically the viscosity is the 75W-90. Also for the tranny you need ATF+4.
