I have a Motive 4.10 ring and pinion. (Still in the car)
Though,. not 100% sure I want to go back to 3.73 or not. With gas prices the way they are going I've been considering the 3.73 again. Almost 3000 rpm in 5th at 80mph is a little much with 4.10. Been considering a 3.90 gear also,.. I love the 4.10.
