The Sentinel Exhaust Brake delivers powerful, fully automated exhaust braking for 2007.5–2027 Dodge Ram trucks equipped with the 6.7L Cummins, restoring dependable downhill control when factory exhaust braking is no longer effective or the OEM turbo is upgraded.
With the ability to generate braking force up to 80% of your engine’s maximum output, Sentinel provides strong, consistent engine braking to reduce brake fade, protect service brakes, and maintain safer downhill speeds under load. Sentinel operates as a dedicated external exhaust brake, delivering reliable braking performance independent of turbocharger configuration.
The system is fully automated, opening and closing seamlessly with throttle input. Installation is straightforward—often completed in under an hour—and every Sentinel Exhaust Brake is backed by a lifetime warranty. Sentinel requires no ECM or TCM programming, no air compressor, and no special equipment, operating instead with a durable, gear-reduced electric motor built for real diesel work.

WHY ADD AN AFTERMARKET EXHAUST BRAKE TO A 6.7L CUMMINS?
When Factory Exhaust Braking Is No Longer Available
On the 6.7L Cummins, factory exhaust braking is integrated into the turbocharger. When the turbo fails or is replaced with an aftermarket unit, exhaust braking is often lost entirely—leaving drivers relying solely on service brakes.
The Sentinel Exhaust Brake restores reliable engine braking by providing a dedicated external exhaust brake, giving drivers the control they need on long downhill grades and during heavy towing.
Sentinel helps:
· Maintain safer downhill speeds
· Reduce reliance on service brakes
· Minimize brake fade from overheating
· Restore exhaust braking after turbo replacement
· Improve control and confidence under load
SAFETY
Engine Braking Designed for Safer Descents
Long downhill grades and heavy trailers place extreme demands on braking systems.
The Sentinel Exhaust Brake enhances safety by:
· Helping manage speed on long descents
· Reducing brake overheating
· Supporting consistent braking under load
· Improving driver confidence while towing
By slowing the engine instead of relying solely on wheel brakes, Sentinel delivers safer, more predictable downhill control.
HOW SENTINEL WORKS
Sentinel uses an electric inline exhaust valve to create controlled exhaust back pressure during deceleration. This slows the engine and reduces the load placed on service brakes.
Because Sentinel operates independently of the turbocharger, it delivers consistent exhaust braking regardless of turbo configuration.
INSTALLATION
Sentinel is designed for straightforward installation using basic tools.
Typical installation includes:
· Inline exhaust brake installation
· Wiring routing
· Controller connection
Many installations are completed in under one hour.
DURABILITY & WARRANTY
Sentinel Exhaust Brakes are engineered to withstand:
· High exhaust temperatures
· Heavy towing loads
· Long downhill grades
· Years of real-world diesel use
Every Sentinel Exhaust Brake is backed by a lifetime warranty.
