Like the title says Buying Cummins What Are the Best Years And Generations?

I like 03-07 with the 5.9 Is there any year were there was alot of emission stuff? Witch tranny is best 6sp Manual or Auto?

 

Autos are weaker, but quicker, of course. If you looking for a lack of emmisions equipment your looking at the right years. Definitely less than the new 6.7s.

 

Depends on your budget. IMO all the B series are kick ***. Of course, the common rail make some big power stock and can make some sick power with few mods. I like manuals for the bush, autos for the street.

What's your plan here?

 

6.7 are still fairly new and the after market is hard at work. another year or two and you'll be seeing huge HP/TQ numbers. but i think they will have big $$$ with them.

 

I would go with a 05 06. They have a little more HP. The 07 has clean air Junk on them.
