Sentinel Exhaust Brake for 2007.5–2027 Dodge 6.7L Cummins

The Sentinel Exhaust Brake adds powerful, fully automated exhaust braking to 2007.5–2027 Dodge trucks equipped with the 6.7L Cummins, reduces brake fade, protect service brakes, and maintain safer downhill speeds when towing or hauling heavy loads. Many 6.7L Cummins owners upgrade to an aftermarket turbo, which often removes the factory exhaust brake function. Sentinel provides a reliable exhaust braking solution for trucks with or without an OEM exhaust brake, making it an ideal choice for both stock and modified Cummins platforms. With the ability to generate braking force up to 80% of your engine’s maximum output, Sentinel delivers strong, consistent exhaust braking performance. The system is fully automated, opening and closing seamlessly with throttle input. Installation is straightforward—often completed in under an hour—and every system is backed by a lifetime warranty. Sentinel requires no ECM or TCM programming, no air compressor, and no special equipment. It operates using a durable, gear-reduced electric motor and functions independently of turbo configuration.

WHY ADD AN EXHAUST BRAKE TO A 6.7L CUMMINS?

Turbo Upgrades Often Eliminate Exhaust Braking

Many aftermarket turbos designed for performance and towing do not support factory exhaust brake functionality. This leaves drivers without effective engine braking—especially noticeable on long downhill grades or when towing heavy loads.

Sentinel restores dependable exhaust braking by providing:

  • Independent engine braking not tied to turbo design

  • Consistent downhill control regardless of turbo configuration

  • Reduced brake fade and wheel brake wear

  • Improved confidence when towing heavy loads

Whether your Cummins is stock or modified, Sentinel provides reliable exhaust braking when it’s needed most.

SAFETY

Engine Braking Designed for Safer Descents

Long downhill grades and heavy trailers can quickly overwhelm service brakes.

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 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 ideal for the 6.7L Cummins:

  • No air compressors or air lines

  • No ECM or TCM programming required

  • Independent operation from turbo system

  • Automated braking control (manual option available)

This design ensures consistent exhaust braking even on trucks with aftermarket turbochargers.

INSTALLATION

Straightforward Installation — Often Under an Hour

Sentinel is designed for easy installation using basic tools.

Typical installation includes:

  1. Inline exhaust brake mounting

  2. Wiring routing

  3. Controller connection

Because Sentinel operates automatically, it provides consistent braking support without requiring constant driver input.

DURABILITY + WARRANTY

Built for Real Diesel Use — Backed for Life

Sentinel Exhaust Brakes are engineered to handle:

  • 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.

FITMENT

2007.5–2027 Dodge 6.7L Cummins

Fitment depends on:

  • Exhaust pipe diameter at the install location

  • Available clearance for inline mounting

  • Existing exhaust routing or modifications

Bundy Motors can assist with fitment confirmation before or after purchase.
