Jacobs Exhaust BrakeThe 2003 Jacobs Exhaust Brake provides more peak retarding horsepower than previous Cummins 24-valve engine exhaust brakes for the Turbo Diesel in Dodge Ram Heavy Duty pick-ups. A new fingertip power switch that mounts directly to the six-speed gearshift activates the brake. The system improves braking control, particularly when towing heavy loads, and can reduce vehicle brake wear. Cummins and Jacobs jointly engineered the 2003 Jacobs Exhaust Brake. It is the only genuine Mopar exhaust brake, and the only exhaust brake approved by Cummins for the Cummins Turbo Diesel.
