Lucky 2003 HO owners ;), what's your RPM with the M6 transmission and the 3. 54 differential (on stock tires)?



Thanks, Dan
 
3:54's are not available on the 03's. You have a choice of 3:73 or 4:10. My 00, with 6spd. , 3:54's and 235x85R16 tires turns 2000RPM at 70 mph. The 03's with 6spd. 3:73's and 235x80R17 tires turns 2050 RPM at 70 mph. Hope that helps.

1750 in 6th, but who goes that slow!



Should be 1650 with an auto.

colors?

That's correct, 3. 73 and 4. 1. But does anybody know whether or not the 03's come in 2-tone colors? The largest dealership in the world (Christopher's in Denver) didn't know. They said Dodge sent trucks but no brochures.

Sorry, no 3. 54 anymore. Just 3. 73 and 4. 1.
 
R.P.M.

The auto has a slower final drive than the 6sp. ???



How much, and what does that convert to in MPH. ??

A 3. 73 in a six speed has an overall ratio of 2. 72:1 ( 6th is 0. 73:1 )

A 3. 73 in an Auto has an overall ratio of 2. 57:1 (OD is 0. 69:1 )



Thats about 5. 5% lower revs for a given speed in an auto.
