Description
Performance Improvement. Get your V8-powered GT up off the line quicker by installing a set of 3.73 SR Performance Ring and Pinion Gears. A steeper set of Gears will place your 2005-2009 GT into its power band much quicker for faster off the line acceleration and a noticeable increase in low end grunt. These 3.73 Gears are a great choice for both street and track applications.
3.73 Gear Ratio. 3.73 gears are a great combination of performance and fuel economy that are ideal for a daily-driven Mustangs that see a lot of highway time. If you put a lot of miles on your Pony and don’t want to increase your cost at the pump, a 3.73 ratio will still give you the added acceleration you want without dramatically compromising fuel economy.
Quality Construction. SR Performance manufactures their ring and pinion gears from forged 8620 triple alloy steel for superior strength. Featuring CNC cut and lapped gear teeth, SR Performance completes their gears in a black oxide finish for long lasting corrosion resistance.
Recommended Upgrade. Changing the rear axle gear ratio will throw off the calibration of your Mustangs speedometer, but a Handheld Tuner or a Ford Racing Speedometer Recalibration Tool is quick and easy way to fix this issue.
Professional Installation Recommended. The installation of Ring and Pinon Gears can be a very intricate process, so mechanical experience is highly recommended. Follow the included instructions for best results.
Application. This 3.73 SR Performance Ring and Pinion Gear set will fit all 2005-2009 GT Ford Mustangs equipped with a 8.8″ rear end. 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.
