Exhaust Brakes

Exhaust brakes help a truck slow down by restricting exhaust flow. Exhaust brakes are generally installed behind the turbocharger, but can be installed virtually anywhere on the exhaust system. An exhaust brake consists of a butterfly valve inside of a turbular housing. A solenoid or spring opens/closes the exhaust brake as necessary. In the open position, exhaust flows at normal rates. In the closed position, exhaust backpressure is created. The backpressure works against the pistons as the engine pumps air out of the cylinder, slowing down the engine and truck. Some exhaust brakes are completely mechanical, while others communicate with your engine's PCM (computer) to provide precision braking. Exhaust brakes are great for controlling speeds when towing downhill or bringing heavy loads to a halt. Using the exhaust brake will also save your truck and trailer brakes, since less braking will be required.

- Controls speed when hauling/towing downhill.
- Reduces brake wear and reduces risk of overheating brakes when towing.
- Decreases distance in which your truck and trailer can be stopped.

- N/A

- Exhaust leaks before the mounting point of the exhaust brake should be repaired to ensure maximum efficiency.

All Power Stroke, Cummins, & Duramax engines.

There are many units on the market which use different methods to control the exhaust brake. Shop around and find the unit that best fits your needs. If you tow frequently, an exhaust brake is well worth the investment. 6.7L Power Stroke, 6.7L Cummins, and 6.6L Duramax LML powered trucks come with factory exhaust brakes.
