Best Rear End For Running Reefer In The West
I am in the market for a newer truck and will go 2008 or newer because I run THROUGH california and only pick up there once in a while.
I run reefer from seattle to dallas and run through the mountains on a weekly basis. Fuel economy is a priority even with the dpf issues...
I would like to know what rear end would be suited for my business. Like I said I run reefer grossed out at 80k and run from seattle to dallas and some cities inbetween.
I will be going 13spd and was wondering what rear end I should go.
All I know is that the lower the ratio...the lower the rpms but won't pull hills and the higher the ratio...3.36 3.42 3.55 the higher the rpms but hills will be easier.
I don't race uphills so I would like a well rounded rear end for my needs. I guess tire size will also affect the rpms?
Would 3.36 or 3.42 or 3.55 be better? I usually dont go past 65mph on 13th and was wondering what rpm i should be at?
Also, if i go 10spd what rear end would be better for that?
Is there a link on where to find out how much your rpms will be with a certain transmission rear end and tire combo that is easy to use? I think I tried the eaton one and I couldn't figure out what number to input for
"transmission final drive ratio"
Is this a worthwhile discussion?
