Description
Improve Off The Line Acceleration. A set of Richmond Excel 3.55 Ring and Pinion Gears are a great way to get your V6 powered S197 Mustang up off the starting line faster. Most 2011-2014 3.7L V6’s came factory equipped with 2.73 or 3.31 gears, which are fine for the daily commuter who is concerned about gas mileage, but not for you the spirited driver. By upgrading to a steeper set of rear gears your Mustang will enter into the power band much sooner for increased low end torque and quicker acceleration. Richmond’s Excel 3.55 Gears are ideal for drivers who are looking to improve the driving performance of their V6 Pony.
Superior Quality. Richmond proudly manufactures their Ring and Pinion Gear Sets right here in the USA. Using state-of-the-art manufacturing processes and extensive quality control testing, Richmond produces a superior quality Ring and Pinion Gear Set at an excellent price. Richmond is so confident in the quality of their products that they back them with a 6 month, 50,000 mile no-nonsense warranty.
Required Upgrade. Starting in 2010 Ford changed the inner rear gear pinion bearing in all 8.8″ equipped Mustangs. Because of this you will require a new 8.8″ rear gear pinion bearing (Ford part# 9L3Z-4630-A) for proper installation, please see drop down option above.
Recommended Upgrade. Please note that when changing the gear ratio of your Mustangs rear differential that the calibration of your speedometer will no longer be correct and will display the wrong speed. However, you can easily fix this annoying issue with a Handheld Tuner (sold separately).
Application. This 3.55 ratio Richmond Excel Ring and Pinion Gear set will fit all 2011 to 2014 3.7L V6 Mustang models equipped with an 8.8″ solid axle 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.
