Pretty sure carriers are needed after 3.73 for 3.08 only least in the rear. Im unaure about the front still.

Scottie my shop guy texted me back saying that new front carriers are also needed for those running 3.08 and going to 3.42 and after.

Ya but i have 3.42 going to 4.10, thats where im unsure, i know in the rear, 3.08 to 4.10 needs new carrier, but 3.42 to 4.10 doesnt.

Not sure if 3.42 to 4.10 in the front requires carrier.

I just thought that it depended on what side axle you have which goes by what engine you have when it comes with the K2s. So me having the 5.3 that means I have the 9.5" rear end so I figured all I would need is a ring and pinions for a 9.5" rear and whatever side the front is which is probably the same as at least the previous gen (07-13).

Ahh. Gotcha! From what my shop said 3.42 fronts are good to go!

So 3.42 is just a ring/pinion change and I believe axles then? Perfect much cheaper to do myself and not do carriers

Im bolting my built engine in the car as we speak so I'll have to start buying up my gearing for the truck soon hehe

I'm not too sure I need to call the shop and ask them. The front is what has me a bit confused
