Whatever is in the front of the tremor seems to get power to both front wheels. If your going to go with tremor take offs I wouldn’t bother putting a locker in the front.

 

do you have the 10.5 rear or the m275?
4.30's are available through nitro gear for the 275.
if you're doing gears spend the money for a traction device up front. true track if you ever plan to use 4x4 in slippery places like ice or snow, go with a truetrac

 

I am assuming that it is the 10.5, but since the dealership was having problems pulling up the build sheet for my truck I don't really know.

 

Its definitely the 10.5

 

Has anyone swapped 3.55s for 4.30s on a 7.3 gasser yet?

 

just google sterling 10.5 on your phone while your looking under the truck. either it looks the phone image or it doesnt

 

the differenced is very apparent. the m275 dwarfs the 10.5.
if its the 10.5 there should be a ton of gear options
