Has anyone ever broken and NV5600 input shaft? Mabey towing a 28' gooseneck with 500hp and a dual disk isnt a good idea. Will post pics of the destruction later.

 

ouch. what were you doing at the time?

 

Post'em, I'm the same boat minus the 500 hp and DD

 

good lord! that takes some.

i meant to say, good lord that takes some doing!

 

 

Just broke mine today pulling a 14-16,000 lb gooseneck pretty much sucks mines runnin about 425 hp 2wheel drive sb dd 3600lb plate rating

 

Small one or big one?

 

those shafts arent suspose to break on the 6 speeds

 

Nice carnage....

 

Unsprung hubs are killer on shafts and splines. My last unsprung hub in a T56 turned the input shaft splines into razor blades. I'll never put an unsprung unit in anything short of a track rat.

Need more pictures of the ends. Can't tell if it was a clean break or if it had been working on the moment of fail for awhile.

Rough texture = clean break
Shiny = Its been at it awhile
