The Sentinel Exhaust Brake is a high-output, all-electric exhaust braking system engineered to convert up to 80% of engine output into retarding force, delivering industry-leading braking performance for towing and heavy use. Sentinel’s electric actuation provides fast, consistent braking with fewer failure points. This is why our durable, simplified design is backed by a true lifetime warranty. 

Sentinel installs in about one hour with basic hand tools and is guaranteed to fit your diesel work truck. 

Supported Work Truck Applications

Box Trucks

Common in freight, logistics, rental, and moving fleets. Box trucks often operate at high gross vehicle weights and experience frequent braking cycles. An exhaust brake helps control speed on grades and reduces wear on service brakes.

Delivery Trucks

Stop-and-go routes, urban driving, and tight schedules put extreme stress on braking systems. Exhaust braking improves control and consistency while reducing long-term maintenance costs.

Dump Trucks

Heavy payloads and changing terrain make downhill braking critical. Exhaust brakes provide added control when descending grades with a loaded bed.

Service & Utility Trucks

Service bodies carry tools, equipment, and materials that significantly increase vehicle weight. Exhaust braking improves drivability and safety for contractors and fleet operators.
