Everyone seems to be really scared about changing out their stock 3.27 gear with a steeper gear like 3.73, 3.90, or 4.10. I elected to go big or go home and went with the 4.10s. And I'm so happy I did! Here's a video to put to rest all the stories about how terrible the gas mileage is and how much it affects your car... This is a video of me on the interstate running at 65mph, 70mph, 75mph, and finally 80mph. The speedometer and RPM gauge is all correct thanks to my tuner.
Don't fear the gear! 4.10 is amazing!
