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 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. 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.

Do gears affect top speed? Does getting bigger gears like 3.73s and 4.10s make you top out faster at lower speed? I want a gear that will help acceleration a lot but i still like going crazy fast. Can you guys make a top speed clip like where you guys explain the product? That would be great.

  • Yes, higher numeric rear gear will lower your top speed by a few MPH. They will also make your car quicker to get to top speed. Do not fear the gear.

    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.

    Ford Racing 3.73

    I bought these gears in January for 179.99 and paid the shop 200 bucks for the install. i drove around a couple times for around an hour and then let it sit over night and the whine went down alot the shop said it needs to get a good heat pattern. The gears really wake up you mustang. It plants you in your seat much more then the gear set 3.27 that was in my mustang. Really good performance upgrade for only spending 379.99.

    Great Product

    Once these gears were in there, the car was a beast and burns rubber like crazy! Should be everyone\'s first mod. Don\'t fear the gear! Also, American Muscle never stop impressing me with their great customer service.

    Awesome Kit!

    i bought this kit ( 3.73 gears/ royal purple oil/partial installation kit/ speed re calibrator) a little over 2 years ago and just now got time off from school to install it. All i can say about this kit is WOW. everything went together perfectly, no flaws with any of the products sold, and of course the customer service was over the top! Even if my experience was 2 years ago, American Muscle has topped anyone i have bought from leaving a lasting impression. Since this was my first time installing gears, i decided to do it the right way and rebuild the whole rear, which American Muscle had everything i needed for the assembly. My advise to anyone looking at gears: Don't go lower than 3.73, and go with Ford Racing parts. whether going n/a or using a power adder you will undoubtedly notice a major difference and still have comfortable highway driving. Another thing i love about the FRP gears is the fact that all you have to worry about is backlash. The pinion gear has a raised ledge on the back face to compensate for the smaller facing, the good thing is that you can reuse the old pinion shim. Saves a bunch of headache!!

    '98 GT auto, The Get Up and Go feeling is there! What a rush!

    This mod should be one of the first to any automatic. It's well worth the price! Not only does the car shift better, the throttle response is there whenever you desire it! It's a must that you order the install kit and go to a reputable shop like I did. I should have bought these earlier but it was a Christmas present from me to me.
