Up Close and Personal with the NEW, high output 6.7L Power Stroke
We got to meet a ’23 Super Duty—with the NEW, high output 6.7L Power Stroke...
2001-2004 LB7 Duramax
GM’s 6.6L Duramax brought common-rail injection, aluminum heads, and 300 hp to the diesel truck segment.
2004.5-2006 LLY Duramax
The LLY Duramax moved the injectors above the valve covers and replaced the IHI turbo with a Garrett VGT.
2006-2007 LBZ Duramax
Higher injection pressure, lower compression, and best-in-class horsepower and torque made the LBZ a home run for GM.
2007.5-2010 LMM Duramax
Essentially an LBZ with more emissions equipment, the LMM Duramax added a DPF on top of EGR.
2011-2016 LML Duramax
The LML brought higher injection pressure, improved horsepower and torque, and SCR emissions technology to the Duramax line.
2017-2024 L5P Duramax
A Denso fuel system, an in-tank lift pump, a billet wheel BorgWarner VGT, and more than 900 lb-ft of torque made the L5P Duramax competitive right out of the gate.
