Description
Improve Overall Performance. A set of Motive Performance gears will wake up your Pony and get it moving faster off the line. Steeper gears are a great way to lower quarter mile times and improve responsiveness without sacrificing driveability. 3.90 gears are perfect for the Pony that needs more than 3.73s but less than 4.10s, offering a great blend of performance and efficiency.

Superior Construction & Precision Fit. These Motive ring and pinon gears are CNC cut from high grade 8620 gear steel, and factory lapped for precision fit. Each set is hardness tested prior to leaving the factory to ensure the highest quality. Unlike other brands, Motive Gears do not have a reputation for "gear whine".

Application. This Motive Performance Plus 3.90 Ring and Pinion Gear set will fit all 2011-2013+ V6 Mustangs. A master bearing kit is recommended by most installers, especially on high mileage vehicles, see drop down option above.

Attention 2010 and newer Mustang Owners. Starting in 2010 Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. Because of this you will require a new 8.8" rear gear pinion bearing (Ford part# 9L3Z-4630-A) for proper installation, please see drop down option above.

Technical Note. Installation costs will vary, but a good rule of thumb is between $250 and $300. Be sure to work with a reliable shop that you trust for installations. You can also save money on your installation labor by having your Trac-Lok rebuilt at the same time as your gears are installed, see drop down option above.

Great get up and go.

I feel that these are the great in between gears to have. I didn\'t want 3.73\\\'s but I didn\'t want 4.10\\\'s either. You will get a great improvement when you hit the throttle.

    Massive acceleration gain

    At first I didnt know if the 3.73 were enough for me so I was goong for the 4.10s and man this 3.90s are way better than both. You dont feel the fuel mileage go that high (mpg) , its definitely even better for fuel economy , I drive it everyday and this thing delivers torque drastically, improved the acceleration at low rpms , it gets speed way faster so that i can be at 1500 2100 rpms and even save more fuel than with my stock 2.73s Have this with bama tune and airaid cai... 13.4 3.7l at 1/4 mile

    STREET FRIENDLY GEAR

    I was looking to make a jump from the weak 2.73 stock gears on the '13 V6 and really add some acceleration. Couldn't decide between 3.73 or 4.10 gears. The motive 3.90's were the perfect choice for daily street and highway driving. 1st gear launch is lot more ballsy. RPM's build up quick and get you flying thru the gears. 6th gear at 70 is a bit above 2g and still getting 22mpg on stock wheels. recommending getting a tuner to correct wheel and gear change so your speedometer is on point. I work in a shop so I set the gears up myself right within spec. No howl or whine during accel or coast to complain about (though I run roush exhaust). Would recommend these to anyone looking for more torque and quicker accel times. Have a pro installation done if you're unfamiliar with the job. Don't forget a pinion bearing and installation shims. GREAT PRODUCT!

    better than 4.10s imo

    Went from stock to 4.10s. that lasted about a year. Decided to go down to 3.90s. They are definatly a much more street friendly gear, but still get up and move! 3rd redlines at about 85, and 4th is around 115, so you'll definatly still have plenty of oomph to blow past the slow traffic on the freeway-
