I bought a 2003 Hemi 5.7L with only 3,400 miles on it for towing and I don't know the redline! Can anyone help? Here is what it is:

2003 Dodge
3500 one ton
duallie
4X4
quad cab
Lariate pkg
5.7 hemi

It does not have the tach marked with a redline and I don't want to push it past it's limit while towing. I can't find it in the manual. This is very aggravating! HELP!

 

Well, the Hemi's have a "redline" at about 5,500 rpm. You'll know it, it won't go past that, it has a rev limiter and will stop power and wont go past 5500. Do you have an automatic? If so, then it will shift at 5500. If you have a manual, and you go to 5500, you'll feel the rev limiter. Try it, its not too bad for it, just to feel it, so you know.

 

my hemi shifts past 5500 closer to 6000+ !!

hmmm maybe thats a bad thing?
