Exhaust Brakes

Exhaust Brakes

Exhaust brakes provide powerful engine braking for diesel trucks engaged in heavy towing or mountain driving. By restricting exhaust flow and creating back pressure, they slow the vehicle efficiently without over-relying on friction brakes, extending brake life and improving control on grades.

Popular Upgrades

Top-selling exhaust brakes include BD Diesel exhaust brake kits for Cummins, Duramax, and Powerstroke applications, butterfly-style exhaust valves for medium-duty trucks, and complete exhaust brake kits that include controller switches and mounting hardware for clean installation.

How does a diesel exhaust brake work?

A diesel exhaust brake restricts the flow of exhaust gases from the engine, creating back pressure that acts as an engine braking force. This slows the vehicle without using the service brakes, which significantly reduces heat and wear on brake pads and rotors during long downhill descents or heavy towing.

Is an exhaust brake compatible with my diesel truck?

Exhaust brake compatibility depends on your engine and exhaust configuration. Most modern diesel pickup trucks with turbocharged engines are ideal candidates. Check the product fitment guide for your specific year, make, and model to confirm compatibility before ordering.
