This is my elusive secret idea! Motor: I think so, Tires: rubber, Axles: yep, Wheel base: Well more than 75" less than 200".

Thanx Jesse but I not giving details yet

I know a np241hd is good to about 950-1000 ft lbs but you will break input shafts if you shockload it while that much torque is being applied so roughly 700-800 reliably

oh and I have seen NP205's take some serious torque in bombed cummins trucks (transplanted) with 1300-1500 ft lb capable motors

Went wheelin with a guy and his buddies from out of town. One of his buddies (whos name is escaping me) was from cali.

It still had the sticker on it. That shaft allowed him to be careless flopping over rocks in his Ford.It held up even though it lost most of the paint on it. And his lead foot didn't help. On top of that he drove the truck home. Jess you guys get my vote. That is one awsome shaft. VERY well made!! Good work!!

You're talking about the input torque, right?

Might as well expand the list to be more inclusive, like torque anyone knows for any tranny or transfer case.

Yeah input torque. I guess if anyone wants me to include torque specs for other models I can. These are simply the ones I'm looking at for my project.

Thanx for all your help!!

No worries, the numbers 451 is a continous torque rating. The stock internals of the th400 can take way more than 451. It's the stock clutches that start giving out when you cross 451.
