AUTOMATIC TRANSMISSION VERSION OF THE JACOBS EXHAUST BRAKE NOW AVAILABLE!

For the 2006 model year, Jacobs is excited to announce the Jacobs Exhaust Brake for Cummins powered automatic transmission-equipped Dodge Rams.  The Jake Brake brand exhaust brake, the only OEM-approved brake for the Cummins-powered Dodge Ram, is available at Dodge dealers and Cummins Distributors in the US and Canada. The Mopar part number for the 2006 exhaust brake (automatic and manual) is 82209823 and the Cummins part number is 4955192. The new exhaust brake utilizes updated powertrain software to maximize torque converter lock-up performance and to protect the Ram's 48RE four speed automatic transmission. This results in up to 170 retarding horsepower to provide enhanced vehicle control and increased service brake life.

Why would I need an exhaust brake for my Cummins-powered Dodge Ram?

Unlike gasoline engines, diesel engines produce no vacuum when you release the throttle to help slow the vehicle.  The higher compression of the diesel acts like a spring on the crankshaft, even with no fueling.  An exhaust brake restricts the exhaust, making the pistons work harder, slowing the crankshaft and the truck.

Exhaust brakes are ideal for towing applications, such as pulling RV fifth wheels and horse trailers. The Jacobs Exhaust Brake is especially popular with Ram owners who drive in hilly and mountainous regions for the added control on steep grades.

You stepped up to the Cummins Turbo Diesel for its legendary torque and performance. Now upgrade to its ideal heavy-duty partner, the legendary Jake Brake brand, Jacobs Exhaust Brake, for added control and brake savings as well!

HOW IT WORKS

The Jacobs Exhaust Brake® is a supplementary braking system used to help slow your vehicle. This slowing power is achieved by restricting the flow of exhaust gases and increasing back pressure inside the engine. This increased back pressure creates resistance against the pistons in your engine, slowing the crankshaft's rotation and ultimately helping to slow your vehicle.
