Looking for firsthand experiences with Cat 3406 engine

Just my opinion...

That 2.79 ratio will probably make that truck feel sluggish.

Combined with a 10-speed that's probably a lot of downshifting when you hit Hills.

And my own personal opinion is I don't like the Kenworth 8 bag air ride.

Not only do you need 8 airbags, there are all kinds of bushings and pivot Points on there that is very over complicated as far as I understand it.

Most of the other manufacturers like International Freightliner Peterbilt they use something similar to The Airliner suspension which is pretty simple.

 

I have the E. I can tell you that Cat is a club membership only group. Computers everywhere and you can not get one that will program a Cat, not unless you work at Cat.

There famous for blowing headgaskets around cyclinder 5. For some dumb reason they put a "spacer plate" between the head and the block to help blow headgaskets. And get this, Cat made the head bolts for a socket only Cat can provide, and maybe Snap On.

Turbo's are twice the amount than any other normal priced turbo, and no they don't put out more power or last longer, on my 3rd one now.

Most parts available for this motor are only at Cat. Some you can get on Amazon about 300% less than what you pay for at Cat and just as good
