01-10 GM 6.6L Duramax Allison Billet Input Shaft

Discontinued (Updated 1/21/25)

High horsepower engines need strong transmissions behind them.  Upgrade your Allison's input shaft with this virtually unbreakable shaft. 

Don't sit on the sidelines with a broke transmission or have it fail in the heat of competition.
