Ok, please tell me if all of this is right. I'm looking for some lower gears for my truck, so I'm going to buy ring and pinion and carrier from a Dana 44 front end with 4.09 ratio, and the ring and pinion for a Dana 60 rear with 4.10 ratio. The guy with the 4.09 front is telling me that he was running 4.09 front and 4.10 rear before he took it out and it's a thing that chevy does stock... I'm just confirming that this is true. Also, he says that I need the carrier he has for the new 44 gears for 4.09 and higher but I won't need a new carrier for the new 60 gears unless I got 4.56 or higher... and I'm getting 4.10 gears. Is this correct as well?
