Can you guys that own 4500's and 5500's list the transmission your using, tire size and rear gearing and tell me what your RPM's are at say 60 mph?

I am trying to get a handle on what rear I may want when ordering a new truck. I know the rears are a lot lower than I am used to but the tire sizes are larger also. I will be running around 23k gcvw.

thanks

 

Aisin Auto 4.88 rears- 2050 @ 62Mph. Just perfect for towing.

 

What kind of milage are you getting loaded and empty and how much weight do you pull?
thanks

 

Empty about 14.5. I never really hand calc loaded because it $varies so much but the overhead says about 8.5-9. The most i will pull is 17K on the 35' gooseneck. Also, the truck weights 12k empty with the deck. Im registered for 30,026 gross minus the trailer weight

 

Thanks for the info.

I will probably go with the auto 4x4 with a 9' aluminum flatbed but still don't know about the rears. I want to get the best milage I can towin my 15k fiver.

I know with the 19.5" tires the rear can be lower and is offset by the tire size. I don't want to go to high but how do you think the 410's would work?

Anyone towin and runnin 410's???

 

A little late but the 4.44s with a G56 = 2300 at 60-65 MPH. Only a few hundred unloaded miles while waiting on my flat bed but overhead is reading 15.8 MPG. Hard telling how acurate it is but there is a little over 300 miles on her and 5/8 a tank of fuel left.
