Product Description
Extreme Duty Allison Performance with ATS Stage 7
The ATS 313-907-4308 Allison Stage 7 Rebuild Kit is engineered for maximum performance and durability in 2006–early 2007 6.6L Duramax applications equipped with the Allison 1000 transmission.

Factory Allison transmissions are strong, but under increased torque and load, internal components can wear or fail. The ATS Stage 7 kit addresses these limitations with performance-grade clutches, steels, and upgraded internal components that significantly improve holding capacity and overall transmission reliability.
This kit is ideal for Duramax owners pushing their trucks beyond stock limits who need a transmission capable of handling aggressive tuning, competition use, or heavy-duty towing.
