    Performance Improvement. A set of SR Performance 3.73 Gears is an ideal way to wake up the performance of your V8-powered 1994-2004 Cobra. Great for both street and track applications, these SR Performance Gears will place your V8 Pony into its power band much quicker for faster off the line acceleration and more low end grunt.

    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 is a 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 1994-2004 SVT Cobra 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.

      Got a set of these gears when I bought my car and have never looked back. Almost never even used 5th gear before. Did the math and with the 3.27s my car would have topped out of gears at like 230 mph which is ridiculous for a non-supercar. Now with the 3.73s my car would top out of gear at around 180-ish which is 1000x better. Very high grade steel as well. Quality of Strange but way less expensive.
