      Description

      Acceleration Improvement. Designed to handle extreme torque applications, this set of high quality 3.73 Richmond Gears will get you where you're going, faster. Improve the acceleration in your 1994-2004 Cobra Mustang and get into the power band faster to beat the competition at the track.

      Superior Quality. Manufactured right in the United States, Richmond Gear uses only the highest standards to produce the highest quality gears in the industry. Inspected and scrutinized to deliver gears with acceptable tolerances, durability and fit, Richmond ensures only the best in machining, finishing and heat treating of their drivetrain components.

      Recommended Upgrade. When changing the gear ratio of your Mustang's rear differential, the calibration of your speedometer will no longer be accurate and will display the wrong speed. However, you can easily fix this annoying issue with a Tuner or Recalibration Tool (sold separately).

      Installation Notes. An Installation and Bearing Kit is highly recommended by most installers, especially on high mileage Mustangs. Please see ordering options above.

      Warranty. Richmond Gears is so confident in the high quality of their ring and pinions that they are backed by a 2-Year / 100,000 Mile No-Nonsense Warranty.

      Application. These Richmond 3.73 Ring and Pinion Gears will fit all 1994 to 2004 Cobra Mustangs equipped with an 8.8" rear end.

      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 your gears are installed. See ordering options above. Note, a 28-spline S-Spring will be required for 28-spline Mustangs (sold separately) if you opt for the Trac-Lok rebuild.

        Quality built as compared to the material on the ford performance gears little to no whine broke in for 500 miles then changed fluid with gear oil and good to go. Better acceleration too.
