Chevrolet Silverado 1500 Forum : “Which is best rear axle on 3.73 or 4.10 ratio? ”

The 3.73 is easier on gas, but seemingly weaker for take-off power. If you plan to pull a lot of the time, 4.10 would be better.

If u are putting this in a new truck i am assuming its your everyday driver. In this case i would go with the 3.73, u will get decent milage still but will have more than enough torque for a trailer.

depends if your towing or cruising
