What dieseldad suggested.... great info in the FAQs.

Also,
The gears will most likely be 3.73s or 4.10s. And the transmission would be a NV4500

Welcome to the 'Place!

Most everything you are looking for can be found here: http://www.dieselplace.com/forum/showthread.php?t=53309

Those are the FAQ's. They are a sticky on the 6.5 forum, and an excellent resource, along with the search function.

As far as gear ratio and such, being a K2500, I'd assume that it had 4.10 or 3.73:1 from the factory. You can tell by the RPO codes. Transmission will be an NV4500. Not sure exactly of transfer case, but, IIRC, it may be an NP241, though I'm not positive if the 3/4 tons got those or not.

Edit: I was too slow.
