Motive Gear Performance Plus Ring and Pinion Gear Kit; 4.56 Gear Ratio (05-09 GT)
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 2005 to 2010 V8 Mustangs including the GT, Bullitt and GT500 models. A master bearing kit is recommended by most installers, especially on high mileage vehicles, see drop down option above.

Please Note. Due to the high numeric gear ratio, it will require a notched gear cross pin for proper installation.

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.
