Thinking about putting 3.73 gears in my 09 v6.Does anyone know of a mechanic in the binghamton area who can install them? My mechanic doesn't feel comfortable doing it glad he was honest about it anyways as i know you have to know what your doing. Any help would be great .

You might want to look at 355 as an alternative. They would improve the ride but not pull down the gas mileage alot. The gears also cruise well getting to that 70 MPH range and maintaing. :headbang:

Wondering if the 3.55s would be a big difference over the 3.331s

You will feel the difference. I had 331 in my 2010 GT and 315 in my 14 5.0. Switched both to Ford Racing 355. My 2015 GT was ordered with 355 gears as well. Its still a preference though. 373 are more agressive .:headbang:

I've got 3.73s right now.. problem being is 3.55 doesn't come in a 7.5 ring gear. I'm going up to 8.8 when I find the right one mostly just for the 3.55 lol

You are correct . The 355 will fit 2011-2014 V6 8.8 The gears are an improvement over 331 . 373 TRACK PERFORMANCE mod. They are sweet. 355 will not fit a 2005 or 2006. Did not look closely at the year saw V6..............;):mechanic::headbang:

don't go leaving out the redheaded stepchildren. lol with the 5 speed tranny you're probably looking at revs around 2300 at 70. depending on where you drive 3.73s are great. I push too much highway (65-75 mph) for them, and I'm a 4 spd auto.

Yes, I realized after I had them installed. D'oh.

I have a auto compared to the 4.10 s the 3.73s will work good for highway and street if you keep it 65-70 as for mpg doesn't matter for me it's a mustang :)

Not sure the v6 cars are a 8.8 so be careful ordering 373.
