      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 drivability. 3.73 gears is a great addition to daily driver, automatic transmission Mustangs, offering a superior combination of performance without sacrificing fuel economy.

      Superior Construction & Precision Fit. These Motive ring and pinion 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 3.73 Ring and Pinion Gear set will fit 2010-2014 GT, BOSS and GT500 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. Due to this, installation 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.

        5 2013 GT - Lucky13 Installation Time: Afternoon

        Should be near the top of your list

        I have several of the usual mods on my 2013 GT (Boss 302 intake, CAI, long tube headers, SCT tuner, etc), but I can tell you without question that the gears have made the biggest impact on acceleration. I've experienced small increases with each change to the car, but the 3.73 felt like a quantum leap. It's really effective in turning that increased horsepower into acceleration you can feel. I used a professional ring and pinion shop for the install, and have no whine at all. Best money I've spent so far.

        great product

        I love these gears I would tell anyone who asked to get these for there car .The install was fairly easy just remember to buy a complete install kit and when doing the install keep parts that you use again marked and they go back to where they came from.

        Good bang for your buck

        I bought these gears about 3 years ago and they are very nice. there isnt gear whine like richmond as long as they are both shimmed correctly. you can def feel the get up and go vs the stockers. You will have to buy either a speed cal or new speedo gear if you have a mechanical speedo.

      1 Top Rated Question

      Fit 2011-2014 V6? Will these gears fit a 2012 V6? Its seems most/all other gears seem to be interchangeable since it has a 8.8" rear. Thanks.

      • As long as you have the 8.8, the Motive Performance Plus 3.73 Gears (10-14 GT, GT500) would work for your V6! They do use the same gear, we just separate it on the website for simplicity's sake.
