that's what i thought is that all 20's have 3.92 to turn the heavier mass of wheel?
If RPM is ~1400 at ~55 MPH, it's 3.55 (or 1800 @ 70)
if it's ~1550 at ~55 MPH, it's 3.92 (or 2000 @ 70)
thankfully, dodge is good at spacing the tach out enough to read every 25 RPM almost :P

i dunno how quick it will be this time of year with everything that's going on and all?????
I thought I read somewhere that ALL 1500's with 20's and the Factory Tow package came with 3:92's.
But not all 1500's that have 20's have 3:92's but rather 3:55 unless ordered with the 3:92's?????

I can walk two doors down from my mother's house and see an '06 Hemi QCSB 4x2 with stock 20's and tow package and he has 3.55s...
