[707 horsepower]

What is the standard and optional rear end ratio for a 2016 Challenger Hellcat with an M6?
Thanks.

Hi,

Not positive but believe the Hellcat M6 gets a 3.70 and is the only option, the Scat Pack M6 get 3.90's with no other choices

3.09

So you're saying the Hellcat Challenger M6 standard rear ratio is 3.09?

Search dude. You’re asking a question about a 2016 Hellcat.

707/717hp

A8 = 2.62
M6 = 3.70

Those are the standard and only ratios ever available, there are no optional ratios on 707/717hp cars.

I’ve searched myself and never got a straight answer. I have a ‘22 Hellcat WB Challenger 717 HP. With A8 transmission 2.62 gear. And Was thinking of upgrading the rear gear to a 3.09 which comes in the Redeye as an option (I think) or standard.
Anyways my question is: Does the speedometer readjust itself after I have a 3.09 gear installed? Or do we have to use a tuner to readjust it? And the odometer will also show you’re putting more miles on it than you actually are.

On the speedo, starting in 2015 the readings come from data supied by the wheel speed sensors so the car can adjust to a gear change and no tune for speedo reading is needed like before.

Does it go off the rears or fronts? One wheel? Average? I have a reason for asking....

People say the fronts but I think it's an average because every now and then you will still get a hero run that's too quick to be real.

I ask because last year I did Land Speed Trials and my tickets pretty much exactly matched my speedo. This year I had same size but different brand tires on the rear and the speedo read about 1.5mph higher than the ticket.
