Description
Improves Off The Line Bite. Are you looking to install a steeper set of gears in your Pony to get more low end grunt off the line? Then look no further than a set of Richmond gears. Richmond has been making high quality gears at a friendly price for well over 80 years. Made in the USA. Manufactured right here in the USA, Richmond uses state-of-the-art manufacturing and extensive testing to produce a superior quality ring and pinion gear set at an excellent price.

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 Richmond 3.73 Ring and Pinion Gear set will fit all 1986 to 1993 V8 Mustangs including the GT, 5.0 LX, 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. 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.

    great gears

    April 14, 2011

    these gears are great! i had stock 273's in my convertible lx and they were no fun. now my car darts off the line and i feel the power all the way through the RPMs. Installation's a little pricey but worth every penny. Gas mileage does not change much as well
