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. 3.73 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 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".

Recommended Upgrade. Changing the rear axle gear ratio will throw off the calibration of your Mustangs speedometer, but a new Speedometer Gear is an inexpensive way to fix this issue.

Application. This Motive Performance Plus 3.73 Ring and Pinion Gear set will fit all 1986 to 1993 V8 Mustangs including the GT, LX 5.0 and Cobra models. A master bearing kit is recommended by most installers, especially on high mileage vehicles, 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 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.
