I wouldn't go with a slushbox. Very inefficient.

Whut do YOU have against Allison??? :lol: :lol: :lol:

It's simple, slushboxes aren't efficient. They're ok maybe for playing in the mud, but anything other then that, a regular transmission or autoshift is fantastic.

two more options: heavy duty drive line and dual smoke stacks...does it make sense to pay extra for either of these options?

This is the spec we run for our heavy haul truck.

Mack CH613

E7 427HP

Mack 13spd

18Fronts 44Rears 20Lift Axel

226" WB

This truck runs mainley on flat land and has been knowen to gross up to 175,000lbs.

Yes I would go with the heavy duty drive line.

Another driver told me getting heavy duty Spicer drive line makes no sense with a Super 40 rear end...says it puts the pressure to break on the rear end...
