Vintage Cummins Power

What is the last year that the 5. 9 Cummins was available from the factory with a six speed manual transmission and factory exhaust brake?

'07 5. 9. My neighbor has one. Dave Smith Motors installed the Jake brake. You could order them,but the brake was dealer installed.

The last 5. 9L trucks came off the line at the end of the '06 calendar year. Mine was built October 9, 2006.

Mine was built Dec. 16, 2006. I was one of the lucky ones to get mine with the late G56

I agree. I'd love to have the AE ratios.

Thanks. This will end a debate with my co-workers.

Yep, Jan. 01 2007 is when the new emmisions took effect, everything built after that has the new 6. 7.
That means the '07 M. Y. came with both motors depending on the build date.

factory exhaust brake?

I don't think the 5. 9 ever came with a factory exhaust brake did it?
