    Features & Details

    • Ford Racing Quality
    • Strong Forged Construction
    • 4.56 Gear Ratio
    • 8.8" Ring Gear Diameter
    • For Street or Track Use
    • Fits 2011-2014 V6 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 Pony. Ford Racing Ring and Pinion Gears are perfect for street, road, or race use.

    Superior Quality. These Ford Racing 4.56 Mustang ring and pinion gears feature a super strong forged construction, CNC cut & lapped gear teeth, and a black oxide finish to resist corrosion.

    Application. This Ford Racing Ring and Pinion Gear set will fit all 2011-2014 V6 Mustangs. A master bearing kit is recommended by most installers, especially on high mileage vehicles, see drop down option above.

    Please Note. Due to the high numeric gear ratio, it will require a notched gear cross pin for proper installation.

    Attention 2010 and newer Mustang Owners. Starting in 2010 Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. Because of this you will require a new 8.8" rear gear pinion bearing (Ford part# 9L3Z-4630-A) for proper installation, please 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.

      Ford 4.56 Gears

      Just had these installed by my local transmission shop in my 1999 4.6L F-150 2x4 with 30 inch tire. I am still breaking in the gears but can feel that the truck is much stronger on the street and goes through the gears much faster which feels a lot better than it did. It is not too much gear for the highway which I was concerned, but is not my daily driver and mainly drive street. At 70mph I currently run 2500 RPM with overdrive. Just a side note if u get these gears with 8.8 rear u need the cross pin with notch cut out because they will not fit with oem cross pin. I installed gears along with Yukon axles and ford cobra rear differential and is very drivable even on wet roads. I can't wait to finish break in period and see what she can really do.

      Sweet ratio

      I have a 2013 3.7. Had 3.73 for awhile. was nice at first but was too used to it and needed something new. Most go from 4.10 maybe to 4.30. Didn't see anyone try 4.56 yet though. Figured why not? I did the install myself. Make sure you get an installation kit and a pinion bearing (x2 bearings if you do the install yourself, one will be a dummy bearing). Also I didn't realize this at first but since this is such a high gear ratio it requires the cross pin to be cut. I did it with a grinder and a vice no big deal at all just a little extra time. VERY good pickup. I blew the car sideways the first WOT. It will chirp between 1-2 and burnout from a red light when you floor it. Very impressed. 1st gear is not useless (everyone will try to tell you that 1st will be useless. 2nd is insane. It will rollout in any gear, any speed, any rpm. Doing about 2750-2800 @70. I don't care. I'll pay for the extra gas. It's fun. Completely worth it.
