The New Jacobs Exhaust Brake for Automatics.
Across the country there are Dodge Ram Turbo Diesel
owners that absolutely swear by the increased braking
performance of the Jacobs Exhaust Brake. Yet, until now,
the Jacobs Exhaust Brake has only been available for
manual transmissions. Now, for the 2006 model year,
Dodge and Cummins have announced that the Jacobs Exhaust
Brake is also available for the 610 Turbo Diesel pickups
equipped with automatic transmissions.
The Jacobs Exhaust Brake provides you with a greater
ability to slow your pickup truck and stay in control Ė
especially on tough downhill runs. This makes for extra
peace of mind when youíre towing a load. In fact,
exhaust brakes are recommended for most towing
applications such as RV fifth wheel trailers, horse
trailers, flatbed and farm trailers.
at Dodge, Cummins and Jacobs Vehicle Systems jointly
designed the Jacobs Exhaust Brake and itís the only
exhaust brake that Mopar endorses for the Dodge Ram. So,
the Jacobs Exhaust Brake is specifically created to work
with your Cummins Turbo Diesel. It transforms horsepower
into braking power by using a butterfly valve in the
exhaust system. This results in up to 170 retarding
horsepower. When activated, this valve restricts the
exhaust flow and increases backpressure in the engine,
slowing your Dodge Ram pickup and reducing the use of
your service brakes on both downhill grades and level
land. In fact, the Jacobs Exhaust Brake can help your
service brakes last up to three times longer!
The new exhaust brake also utilizes updated power train
software to maximize torque converter lock-up
performance and protect the Dodge Ram 48RE automatic
transmission. Itís designed with the exhaust brake and
automatic transmission controller integrated into the
engine which eliminates the need for an external lock-up
The Jacobs Exhaust Brake is 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 (57,936 km)
warranty on all other kit components.
You can purchase the Jacobs Exhaust Brake as a
dealer-installed option. Plus, you can even finance your
exhaust brake with your new truck purchase. Ask for
