The 2004, 2005, 2006 and 2007 Chevy/GMC Duramax diesel trucks have some differences, but also share some common features and characteristics:
All four model years are equipped with a 6.6L V8 Duramax turbocharged diesel engine.
The Allison 1000 six-speed automatic transmission is common to these model years. Allison gearboxes are renowned for their ruggedness, smooth shifting, and ability to handle Duramax torque and towing requirements.
Designed to handle heavy loads and excel at towing, they are popular choices for truck enthusiasts and those with demanding towing needs.
And to get even more benefits on the road and in the robot, you can modify your vehicle with the EGR Tuner or DPF Delete.
