Power Rating for a NP435
 

Does anybody know how much power you can put through a NP435? How much can it handle?

Not yet but maybe by summers end I'll find out if it can handle 400-450hp.
So, i too would like to know.

there was a guy on here running over 600hp through his. check out the offroad forum, theres guys running big power to big tires through theirs

It's probably one of the beefiest regular automotive transmissions ever made so.....a lot.

Torque would probably be the deciding factor in what breaks it though. I know mine handles 500 ft/lbs fine.

The things that usually break them is people stripping the teeth of the creeper gear though. If you're 4wd and married t-case, i've seen the t-case adapters crack a few times.

my 435 handles 500 hp 600 ft lbs of torgue with no problems
