2003 - 2007 Dodge 5.9L Cummins

Jake Brake Vacuum Pump

- Includes Pulley -

This 5.9 Cummins vacuum pump is the highest quality available - at a fraction of the dealer cost!

Investigation into why the original vacuum pumps for this application had such a high failure rate indicated that the vacuum pump was turning at too high of an RPM.  These pumps feature a re-designed slightly larger pulley so that the pump runs in the correct RPM range for maximum life expectancy. No change in belt size is required.

This Jake brake vacuum pump replaces the following part numbers (and others):
