What is the difference between a 3.73 and a 4.10 gear ratio ?

Picking up my new 2002 Silverado this week. I wanted one with the stock 3.73 gear ratio but this particular truck that I found had a 4.10 gear ratio. What is the difference ? Will I get worse gas mileage with the 4.10 ?

The 4.10 is A lower gear.It will make you run Ahigher RPM.Depending on tran's gearing also.The higher the number the steeper the gear= more RPM.

The image must be available from the internet and then you can use the "img" tag
Type in an [ and then img and then another ] then the web address of the picture and then another [ and an / and img and another ]

Yes, a .410 gear will get worse gas mileage then a .373 BUT it will have more bottem end power too and will have a higher tow rating.

I have 4:10's in my 2000 and can tell you, they only make a couple hundred RPM difference,and seems to keep the truck in a power band it likes. I still get 15.3mpg overall. If you tow at all, you'll really appreciate the 4:10's. These truck should all come from the factory with them.
