      Product Information

      Features, Description, Reviews, Specs & Installation


      • Ford Racing Quality
      • Strong Forged Construction
      • 3.73 Gear Ratio
      • 8.8" Ring Gear Diameter
      • For Street or Track Use
      • Fits 1994-2004 SVT Cobra Mustangs


      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 Cobra. Ford Racing Ring and Pinion Gears are perfect for street, road, or race use.

      Superior Quality. Manufactured in the USA, these Ford Racing Mustang ring and pinion gears feature a super strong forged construction, CNC cut & lapped gear teeth, and are completed in 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 Ford Racing Speedometer Recalibration Tool is an inexpensive way to fix this issue.

      Application. This Ford Racing Ring and Pinion Gear set will fit all 1994-2004 SVT Cobra Mustangs. 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.

        5 1997 Cobra - Michael

        3.73 for 97 cobra

        Picked these up after my pinion seal started leaking and getting gear whine and some whirring coming my rear end. Carrier bearings and axle bearings were toast, pitted aswell. Installed this with the 8.8 master install and carbon disk trak lok rebuilt kit. Remember to soak your carbon disks in friction modifier 24-48 hrs before instal to reduce chatter!! Gears really woke this car up, but are whisper quiet aswell. Worth every penny.. product is exactly how it is described, really nice quality from ford.thanks again AM for fast 2 day shipping. Mike

        Great quality and great gearing for me. 4.10s were a tad bit too much with 700hp.

        5 2004 Cobra - XS

        Bought with plans for taller tires

        I purchased these with plans to move to a taller tire soon. The gears appear to be working as intended. Not gonna lie, I was not expecting the amount of work that was required for installation. I have a 2004 Cobra and it was quite a pain to complete. Very happy with them though.

        Ford Racing 3.73 Ring Pinion Set

        Ford Racing is the only way to go when I order parts. Great FORD quality and setup has been done and my 2004 COBRA is solid and a bit quicker. Thanks

        Ford 3.73

        The ford racing 3.73 gear set I purchased for my 03 cobra has so far been the best mod I've installed yet. Better out of the hole launches and still maintains decent mileage on the streets.

        5 1998 Cobra - bassahaulic Installation Time: Afternoon

        Ford Racing 3.73's for 1998 Cobra

        I decided to go with these gears after destroying my previous rear end, which had Ford Racing 4.10's, doing a nitrous launch. Dropped old rear end, torn down, gear re-installed, and back in the car in less than a day. Gained ALOT of mid range and big end power. Made up for the slight drop in initial power the 4.10's had. Fuel mileage has improved quite a bit, and drive-ability has improved as well. Would recommend to anyone.
