Cummins Diesel Engines & Exhaust Braking

Cummins diesel engines power a wide range of trucks—from light-duty pickups to medium- and heavy-duty commercial vehicles. Known for their high torque output, long service life, and proven reliability, Cummins engines are commonly found in pickup trucks, box trucks, delivery vehicles, buses, vocational trucks, and long-haul commercial applications.

While Cummins engines are built to pull heavy loads, safe downhill speed control is critical—especially in towing, hauling, and commercial use. Many earlier Cummins-powered trucks rely entirely on service brakes, and even newer engines can lose effective exhaust braking when factory systems are removed or when aftermarket turbochargers are installed.

Sentinel Exhaust Brakes provide dependable, fully automated engine braking for Cummins engines across all truck classes. Designed to operate independently of turbo configuration or factory exhaust brake systems, Sentinel exhaust brakes help reduce brake fade, protect service brakes, and maintain safer downhill speeds under load.
