Allison A-1000 2001-2010

Stage 1
This is our improved stock Allison.  It is designed for the stock truck .  It has all the latest updates and will give you years of trouble free service. 

Stage 3
I designed this transmission for every one that is running a tuner, or EFI live.  It is rated for 550 rear wheel horsepower.  This is not a kit slapped in a used transmission.  It has a complete rebuild, all new custom clutches, pump mods, valve body mods, 3 disk billet custom stall torque converter, etc. 

Stage4
This build is designed for the customer that has a tuner, or EFI live, and wants to add injector or a turbo.  I rate this one at 650hp.  You can still street drive it during the week and compete with it on the weekends. 

Stage 5
This build is designed for trucks making up to 750 hp at the wheels.  It has all the internals needed to make it a competition transmission.  You can still drive it on the street, but it is set up to drag race or sled pull. 

Stage 6
This is a competition only Allison.  It is built for up to 1,000 hp at the wheels. It has billet shafts, as many clutches as you can possible squeeze in there and all the best internal upgrades.

Redline Diesel Power Duraflite

This is a 47RE transmission out of a Dodge  that we have built and modified to install behind a Duramax.  It has all billet internals, stand-alone valve body, etc.  It weighs about 150 pounds less than the Allison, it is more consistent when you are making 800 plus hp.  It will make your Duramax faster and more consistent at the track.
