Anyone done this, or know what all needs to be done and where to get parts, or who makes them.

 

i have to ask WHY?!?!?! if it'll tear up behind a stock 180hp Cummins what makes you think it will last behind a Duramax? and what is wrong with the Allison? if you don't like it send it to me.... i'll put it behind my Cummins.....

 

A. 47RE is SOOOO easy to build
B. Because of the nature of the beast the ally will never shift like I want it to shift, never.

 

i c..... i dono.... i'd look into the 48re atleast...

 

I was thinking about the 47RH, but the output shafts are way weak on them because there is basically a hole drilled in them. But with an RH I would need NO electronics to go to it.

 

one word for the output shaft, input and intermediate shaft....

Billet.

 

If you dont billet the output though, it leaves a good, in-expensive, easy to fix weak link. I would billet the input and intermediate, but not the output.

 

Look up Suncoast they have the 48RE that will work with the Duramax thats all Buck Runs after going through 40 Allisons.

Another one thats stronger you might want to look into is the older 747 They can be beefed up like crazy no electronics.

Anyone can make adapter plates.

 

Buck has one. Subman, Nathan, and Idaho Rob have one in their new drag truck. They put down 10.60's is a RCLB last weekend. LB7 w/a fairly mild set of twins.

 

Yeah I knew there was a couple of Members on here with them. Seems to be the way to go when drag racing but the Allison sems o hold up alright Pulling and Dyno I'm Surpirsed Nasty Girl hasn't broke them down.
