Get Going. Crafted from the highest quality materials for your high horsepower SN95, this set of 3.73 Richmond Gears will get you off the line faster. These steeper gears will get your 1994-1998 GT Mustang into the power band quicker and is perfect for both street and track applications.

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 1998 GT 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.

Do I have to buy a bearing and/or installation kit?

RyanG

  • When installing the Richmond 8.8 in. 3.73 Gears an install kit will be needed, however higher mileage cars should consider a bearing kit due to potential wear on the existing bearings.

How much do these 3.73s raise your rpms at highway speeds? Currently I'm at about 1500-1700 rpms at 65 mph, with stock gears.

  • It depends what transmission you have and whether it is manual or automatic, but not to worry! We have a handy-dandy chart here that should give you your answer! http://www.americanmuscle.com/mustang-gear-ratio-to-rpm-chart.html
