Now that my NV3500 is out and my NV4500 is in the only drivetrain parts that haven’t been replaced are my Transfer case and drive shafts. The T case has 115k Miles on it and as far as I know has never had the pump saver installed. Manually shifting it requires a good amount of force and I think it is making a slight rubbing or grinding noise.

I know the NP261 can hold plenty of power Atomic and many other members are proof of that so I plan to replace the factory one with a rebuilt T case with the updated case half. As for drive shafts I know I don't make much power at all right now but eventual goals will be around 600hp and I would like to go ahead and get them squared away now.

Question is what should I have done to the drive shafts?
Have stronger ones built?
Rebalance the factory ones?
Upgraded U joints?

Also for the T case.
What fluid do people like?
Anyone know a good place to buy one?
Any upgrades besides the pump rub fix?


Thanks for the help!
