hawk259 Posted January 5, 2017 With all the recent post about MPG and 2017 stuff, I decided to post something I have been wondering for a while. What if you replaced the 3.54:1 V8 rear end gears with the 3.36:1 V6 rear end gears? I am sure the 3.54 gears are better for towing, but if you never/rarely tow would the V6 gears get you better MPG? My thinking is that the 3.36 would allow the V8 to run at a lower RPM on the freeway (less than 2.5k at 70mph), so it would get better MPG. No idea how much it would hurt acceleration, both standing still or rolling. Granted, I have no idea how to do this with out voiding the 5y/100k warranty. Thoughts?

Jeremie Conley Posted January 5, 2017 I have wondered this myself. On the toll road at 85mph it is disconcerting to see 3K on the tach! Quote Share this post Link to post Share on other sites
aabel Posted January 5, 2017 I think the answer is yes, only if you're driving 80% plus freeway Quote Share this post Link to post Share on other sites
