I have an Np203 transfer case and want a better gear ratio to get my RPMs down what can you use in its place It is 76 blazer?

The NP203 transfer case used in the 1976 Chevy Blazer has a gear ratio of 1:1. If you want to reduce your RPMs, you can replace the NP203 with a transfer case that has a lower gear ratio. Some possible replacements include:

* NP205: 1.96:1

* Atlas II: 1.94:1

* Dana 300: 2.62:1
