There is no need to buyit from the dealership, any speed shop should carry
them.

I agree with you, BUT the Rubi comes stock with 4.10 gears anyway, so it may
work out okay. I stick to 4.56s if I was doing it, so the 4.10s won't be too
bad.

Re: Rubicon question
Someone in this group said the Rubicon automatically recalibrates
speedometer for tire size, like it may have an axle height sensor.

Re: Rubicon question
Jeff, the Rubicon 4:1 T- case IIRC doesn't use a speedo gear, it uses an
induction pickup sensor on a tone ring inside the case.

Re: Rubicon question
I've heard that before too but I can't imagine how it would do that unless
there is some kind of sensor, I'd guess a GPS module.
