I suppose you have the 454 engine?
For a '97 K2500 their were only 2 ratios from the factory.
The 350s were ONLY shipped with 4:10 ratios.
The 454s came standard with 3:73 with 4:10 an option.
Unless you're doing a lot of highway speed cruising the 4:10s give better all-around performance/response.

I have a 1997 k2500 5.7 L31 with 3:73 GT4 stock... However, it has an nv4500. It is also 8 lug.
