Dudes with 3rz and 4.56 and 4.88 gears QUESTION???

So dudes with 4.56 at 80mph what RPM you guys at with the 4 Banger

and

dudes with 4.88 at 80mph what RPM you guys getting?

just trying to decide between gears. i want 4.88 but curious about highway speed restrictions due to high RPMs.

EDIT: also let me know what size tires you are running.

 

no one can help me out? i will take a ball park if that works. i have 3.58s with 31s and i am at like 2300 doing 85ish MPH.

 

yeah depending on what tire size you use will determine your rpms

I plugged in some tire sizes into the tire size calculator, its not perfect but will give you an idea.

if you went from your 31s to 285s (33s)

at 65 with 4.88s it would be at 3246 rpms, and with 4.56 it would be 3033 rpms

if you went to 35s

4.88- 3080 4.56-2878
