Dorman Heavy-Duty Engine Brake Switches

Restore the functionality of the engine brake on your diesel engine-equipped vehicle with a quality-engineered engine brake switch. The engine brake system is used in large trucks to help control downhill vehicle speeds, assist in deceleration, and provide better overall braking than the conventional brake system. Dorman's engine brake switches are made of high-quality materials and designed to restore the ability to engage and disengage the engine brake back to factory settings.
