Heavy Duty Sentinel™ Electric Exhaust Brake

More power under the hood. More control coming down.

Built for performance turbos, upgraded fueling, and serious towing.

You’ve built your diesel to pull. Give it the braking power to handle the descent.

Whether your factory exhaust brake feels weak, your truck never had one, or a turbo upgrade means losing VGT braking, the Heavy Duty Sentinel gives you a powerful, independent exhaust-braking system.

Up to 80% of engine horsepower in retarding power. Fully electric. Throttle automated. Backed for life.

The Climb Takes Power. The Descent Takes Control.

A loaded trailer or heavy hauling changes changed everything. Speed builds quickly, the corners come sooner, and repeated braking puts heat into your service brakes.

Sentinel helps hold your truck back so you can spend less time on the brake pedal and keep more braking capacity available when you need it.

• Strong holdback on long grades

• Less reliance on service brakes

• Reduced brake heat and fade

• More controlled towing and hauling

Put your engine to work on the way down.

Heavy Duty Where It Counts

The Heavy Duty Sentinel pairs a durable valve assembly with an oversized, high-torque electric actuator.

Its worm-drive gear reduction provides the force to move the valve and mechanically hold it in position without continuous motor power. With actuation in less than a second, Sentinel responds quickly when it’s time to get on—or off—the throttle.

Built to work repeatedly, under load, mile after mile.

Lift Your Foot. Feel the Holdback.

With Sentinel enabled, release the throttle to engage the brake. Apply the throttle and the valve opens.

That’s it. No constant switch operation as the road changes.

• Fully automated operation with throttle input

• Manual control option

• No air compressor or air lines

• No vacuum system

• No ECM or TCM programming required

Electric operation keeps the system simple—and keeps you focused on driving.

Questions Before You Buy?

Will Sentinel work with an aftermarket turbo?
Sentinel uses its own inline valve rather than relying on variable turbo vanes for braking. Contact Bundy Motors to confirm the setup for your turbo and engine.

Can I use it with my existing factory exhaust brake?
Sentinel can work with or without factory VGT exhaust braking. We’ll help confirm the appropriate installation and controls for your truck.

What makes the Heavy Duty model different?
The Heavy Duty model uses a larger, more powerful actuator for demanding applications, including performance builds and heavy towing.

Do I need an air system or computer programming?
No. Sentinel is fully electric and requires no ECM or TCM programming.

How do I choose the right exhaust size?
Measure the exhaust pipe diameter at the planned installation location, or go to our Exhaust Brake Selector for help confirming fitment. You can always call us as well.
