Thinking about getting a set of 3.73 gears for my 09 v6 what i'm wondering is what would be the rpms @ like 70-80 mph? i do alot of road trips during the summer, usually at about 70-75 mph .Not to worried about gas mileage but if the engine is going to be really revving at highway speeds

I had 331's that are so common in our cars. I switched to a 7.5 locker, from a Ranger and set of 373's I originally ran 1700-1800 at 70 or about. Now with the 373's I run at 2000-2100. The take off power is so much better with these gears over the 331's. I hope that this helps you with your decision.

Yes that's a big help thanks. I was thinking that the rpms would be higher but 2000-2100 is not a big difference so i think i'll go for it . sct x3 bama tune sd coil taylor thundervolt 8.2 gt takeoff muffler bbk cai koni srt struts kyb shocks seq tail lights
