      Description

      Wake Up Your Pony. Installing a set of steeper gears is a great way to get your Mustang into the power band quicker, for improved low end torque and faster acceleration off the line. A set of USA Standard Gears will really wake up your Pony.

      Better than OEM Quality. Using state-of-of-the-art equipment and manufacturing techniques, USA Standard Ring & Pinion sets are made to higher than OEM standards from high grade 8620 gear steel and are backed by a one year warranty.

      Application. This USA Standard Gear Ring and Pinion Gear set will fit 2010-2014 GT, BOSS and GT500 Mustangs. A master bearing kit is recommended by most installers, especially on high mileage vehicles, see drop down option above.

      Attention 2010 and newer Mustang Owners. Starting in 2010, Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. Due to this, installation will require a new 8.8" rear gear pinion bearing (Ford part# 9L3Z-4630-A) for proper installation, please 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.
