How to Choose the Correct Size
Sentinel Exhaust Brakes are sized by exhaust pipe diameter.
Choose the 5" Sentinel Electric Exhaust Brake (Heavy Duty) if your exhaust pipe measures 5 inches at the installation location. All Sentinel exhaust brakes share the same core design and automation—the difference between sizes is the exhaust diameter and duty rating.
If you’re unsure of your exhaust size or application, Bundy Motors can assist with fitment confirmation before ordering.
