What Differential I have

3.25 is an odd duck for the 10.25.... maybe a bad listing, possibly aftermarket only?

I thought the 3.31 and 3.07 for that diff were obscure already.

That Helps soo much. This is my first truck and first vehicle ive really ever worked on. The learning curve is steep but soo much fun. Thank you so much.

And I thought my turbo 6.9 was gutless with 3.55s!

At least you'd never need an OD transmission
