WHY ADD AN EXHAUST BRAKE TO A DURAMAX?

Power Is Impressive — Control Is Essential

The  2001- 2010 6.6L Duramax is known for strong torque and towing capability, but from the factory these trucks rely primarily on service brakes to control speed on long downhill grades.

When towing or hauling, Sentinel helps:

• Maintain safer downhill speeds
• Reduce reliance on wheel brakes
• Minimize brake fade caused by overheating
• Improve overall control in mountainous or heavy-load conditions

Sentinel is a practical safety upgrade for 2001–2010 Duramax owners who tow regularly, haul heavy loads, or drive long grades.

SUPPORTED DURAMAX ENGINE APPLICATIONS

Sentinel Exhaust Brakes are compatible with all 2001–2010 6.6L Duramax engines, including:

• LB7 (2001–2004)
• LLY (2004.5–2005)
• LBZ (2006–2007)
• LMM (2007.5–2010)

Regardless of generation, Sentinel provides consistent exhaust braking that does not rely on turbo-based braking behavior.

• Automated braking tied to throttle input

INSTALLATION

Sentinel Exhaust Brakes are designed for straightforward installation using basic tools.

Typical installation includes:

1. Installing the exhaust brake inline
