      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.

      Recommended Upgrade. Changing the rear axle gear ratio will throw off the calibration of your Mustangs speedometer, but a new Speedometer Gear is an inexpensive way to fix this issue.

      Application. This USA Standard Gear Ring and Pinion Gear set will fit all 1994 to 1998 V8 Mustangs including the GT and Cobra models. 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.
