Description
Improve Overall Performance. Improve your V8-powered Mustang's off-the-line responsiveness with a set of 4.56 gears from Motive. These high quality 4.56 gears from Motive will give your Mustang more pull off the line and get you into your power band faster for quicker quarters and lower ET's.

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 Ford Racing Speedometer Recalibration Tool is an inexpensive way to fix this issue.

Application. This Motive Performance Plus 4.56 Ring and Pinion Gear set will fit all 1999 to 2004 V8 Mustangs including the GT, Bullitt, Mach 1 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.

Awesome gears for the Mach 1. I did cams and needed to get back some of the lower band power! These did the trick! Car feels like it is ready to move out at whatever rpm you are at. Works great on the

    Awesome

    I have an 03 mach 1 and these gears fit great! I had originally ordered a set of richmond excel's. they did not fit with the stock cover or any other after market cover I tried. The richmonds were to thick. And no one not even the manufacturer could tell me why. The install was done at ford and checked multiple times by different mechanics. I would strongly recommend these over the richmond! The performance gain was also worth the trouble I went through!

    Awesome gears for the Mach 1. I did cams and needed to get back some of the lower band power! These did the trick! Car feels like it is ready to move out at whatever rpm you are at. Works great on the street and the strip.

    These are some fun gears if you have an auto trans. I dont drive on the highway to much but you can for sure. The gas millage isnt good highway but city its not to much worse.
