I know this the wrong section, but this is the only area I can get a response.


I just bought a 05' C4500 4x4 allison w/ Dmax. The truck has a 12' contractors box on it. I am wondering if I can run the same juice mods as on my 03 2500?


From what I know this is the same tranny and motor (lly) as the other trucks.


I will take delivery on this truck in january.


I appreciate the info.

Your 03 has a LB7 so u will need the juice for the 04.5 LLY, assuming it will work on the 4500.
