Jacobs Exhaust Brake for the Dodge Ram   

The Best Brake For The Best Engine.

Now that you have chosen a Cummins 610 Turbo Diesel for its legendary torque and performance, a Jacobs Exhaust Brake® can provide added control and brake savings - by transforming Cummins horsepower into braking power. The Jacobs Exhaust Brake is now also available for Cummins powered Dodge Ram pickups with automatic transmissions for 2006 and later models.

Don't Compromise Exhaust Brake Performance. Or Your Warranty.

Key features and benefits include:

  • Factory-approved for the Cummins Turbo Diesel and endorsed by Mopar, so it doesn't put your engine or power train warranty at risk
  • Backed by a comprehensive 3-year/100,000-mile (160,934 km) warranty on the exhaust brake assembly, with a 3-year/36,000-mile (57,937 km) warranty on all other kit components
  • Designed with exhaust brake and automatic transmission controller integrated into the engine so you don't have an external lock-up box
  • Supported by the largest diesel parts and service network in North America
  • Built by the same people who make the famous Jake Brake®
