My old LN 8000 is in need of lower ground speed under heavy load (Off road) and just better gearing for this terrain.
It has a 8.3 Cummins and a six speed trans.
Low gear at working RPM's is about 7Mph.
That is way to fast for me and the truck.
So i could swap out the transmission. But that would be big money. Maybe more than the truck is worth.
Or i have laying out here a Spicer 6041 4 Speed Auxiliary Transmission.
Trouble is it has yokes for a medium duty drive line.
My truck has a heavy duty drive line.
Do they make heavy duty drive line yokes for this transmission?
If so where would a person find them?
I know it is a little rough.
It is a work in progress.
