May be some better times ahead or ones I have'nt seen yet. As far as rear gear its a 3:92 trac pac. And at 1500 rpm in 6th gear you will be at 60 mph. helps with the better hwy gas mileage.
The window sticker on my R/T say's 3.92 also. Steve the guy with new SRT said 3.91 . I've seen it both way's in advertising . I don't understand that . Can there be two different ratio's . I don't think so good anymore. Too many birthday's. And in the 09 brochure I have they say 3.91 for the track pack for the R/T. What is the story on this. Can someone review how the ratio is figured. How many teeth on the ring gear to pinion. Or what. And did the 08 SRT come with pos or didn't with the automatic. And only the 09 SRT with 6 speed does get the pos .
