While its true that your Ram has a good set of brakes from the factory, nothing gives you stopping power and control like an exhaust brake. Long grades? Heavy loads? 5th wheels trailers? Use your engines braking power and spare your service brakes!
The benefit of an exhaust brake is that it adds stopping power to the regular brakes. This helps prevent them from over-heating and glazing which dramatically decreases their effectiveness. When towing heavy loads, exhaust brakes can save your truck and help you maintain control.
