    Description

    Enhanced Performance. While finally equipped with an 8.8" rear end, the 2011-2014 V6 Mustang could still use a little help in the pep department. Fear not, you can upgrade your gear ratio to these high quality 3.55 Richmond Gears. Designed to easily handle high torque applications, your V6 will see improved acceleration and get into the power band faster.

    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).

    Attention 2010-2014 Mustang Owners. Starting in 2010, Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. Because of this, a new 8.8" Rear Gear Pinion Bearing will be required for proper installation. Please see ordering options above.

    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 3.55 Ring and Pinion Gears will fit all 2011 to 2014 V6 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.
