WHY ADD AN EXHAUST BRAKE TO A 5.9L CUMMINS?
Legendary Reliability Deserves Better Braking Control
The 5.9L Cummins is known for its durability and torque, but from the factory it relies entirely on service brakes for downhill speed control.
When towing or hauling, Sentinel helps:
- Maintain safer downhill speeds
- Reduce reliance on wheel brakes
- Minimize brake fade caused by overheating
- Improve control in mountainous or heavy-load conditions
Sentinel is a practical safety upgrade for 5.9L Cummins owners who tow frequently, haul heavy loads, or drive long grades.
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 service brakes, Sentinel helps maintain safer, more predictable control.
HOW SENTINEL WORKS
Simple Electric Exhaust Braking
Sentinel uses an electric inline valve to create controlled exhaust back pressure, slowing the engine during deceleration.
What makes Sentinel different:
- No air compressors or air lines
- No engine tuning required
- Independent operation
- Automated braking control (manual option available)
This design keeps the system simple, reliable, and well-suited for the 5.9L Cummins platform.
INSTALLATION
Straightforward Installation — Often Under an Hour
Sentinel is designed for easy installation using basic tools.
Typical installation includes:
- Inline exhaust brake mounting
- Wiring routing
- Controller connection
Because Sentinel operates automatically, it provides consistent braking support without requiring constant driver input—supporting safer downhill braking behavior.
DURABILITY + WARRANTY
Built for Real Diesel Use — Backed for Life
Sentinel Exhaust Brakes are engineered to handle:
