Ok guys since I seem to have lost my notes before my lift install, l'll ask for some help from those of you that have a bone stock 2004 4x4 with the LLY/Allison. I'm wondering what RPM's you're turning at 50 mph, or 60 mph. Thanks in advance.

Voodo,


I Just got Back from work, and here it is.


1500 RPM = 50 MPH


1625 RPM = 55 MPH


1850 RPM = 60 MPH


1975 RPM = 65 MPH


2200 RPM = 70 MPH


This is the best judgement I could make as it's rather hard to tell exactly where the RPM'S are when there in between the marks, but if you do the math it makes sense. Note: the tach at 65 MPH is not fully centered on 2000 RPM'S so this is how I determined the RPM'S.


Hope this helps, Fran

04wanabemax,


Thank you!!!!


I looked tonight and seems very close if not the same as what you gave me. Like you said it is hard to tell exactly, I just wanted to get a good idea. Thanks again I'll see at 65mph. The 37's and 4.56 gears seem to be very close to stock.


50 mph 1600


60 mph 1800


Thanks again!
