Description
Improve ET's and low end torque. Are you looking to get more low end grunt off the line and lower ET's at the same time? Then look no further than installing a set of steeper gears in your Pony. Ford Racing Ring and Pinion Gears are perfect for street, road, or race use.

Superior Quality. These Ford Racing 3.73 Mustang ring and pinion gears feature a super strong forged construction, CNC cut & lapped gear teeth, and a black oxide finish to resist corrosion.

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 Ford Racing 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.

    It should have come from the factory with these

    What a great gear set. Mine arrived quickly and with just about all the pieces needed to install it came with the gears. I had them installed at my local drive line specialist about a week ago and since my bearings where still in great condition, all that was needed where a couple of seals and some fluid when they installed them. I have a T5 and went from a 3.27 to these 3.73's and absolutely love them. My LX is a daily driver too. If you are going back and fourth on if you should get gears or not...just do it, you will not be disappointed.

    Good buy for any guy (or gal)

    Bought gears, install kit, and girdle a few weeks ago and had them professionally installed. Very happy with the gears and how well my car pulls now. If you want to make your car a little quicker without major cash, these gears are an excellent choice.

    Awesome!

    Finally installed my 3.73s- wish I had done it sooner. Good luck trying to shift to third- the g-forces will keep you VERY well planted!

    Just crazy acceleration!

    Can\'t believe I didn\'t do this sooner! I went \"crazy\" and threw in a set and the acceleration is just unbelievable. I had it professionally done and had headers/exhaust system installed and changed air intake at same time. This is the best thing I\'ve ever done and it\'s like driving a whole different car. Even the gas mileage is far better than stock. This car is not a \"pony\" anymore. It\'s a \"Ragin\' Bull\"!
