I have 2012 Silverado 1500 Lt front differential when bad, I bought a used one but it was 3.7 and mine is 3.4 my question is can I change the gear ratio in the 3.7 to 3.4  I change the ring gear and the pinion thank you

Might be less expensive to change your rear gears to 3.73s, your truck will certainly like it!

you would need to take it to a shop or dealer to get that done.  It all depends on how much time is involved for them on what it would cost.  A shop might give you an idea, as to how much.  A dealer should have a book for how long it will take, and charge roughly according to that suggestion.
