      • Superior Quality
      • CNC-Cut from 8620 Gear Steel
      • 4.10 Gear Ratio
      • 7.5" Ring Gear Diameter
      • For Street or Track Use
      • Fits 2005-2010 V6 Mustangs


      Improve Performance. Wake up your V6-powered pony for faster acceleration off the line with a set of 4.10 Motive Performance Plus gears. A steeper set of gears will get you into your power band faster for faster launches and more punch off the line.

      Superior Construction. These Motive ring and pinon gears are CNC cut from high grade 8620 gear steel, and factory lapped for precision fit. Each set is hardness tested prior to leaving the factory to ensure the highest quality.

      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 Motive Performance Plus Ring and Pinion Gear set will fit all 2005 to 2010 V6 Ford Mustangs equipped with a 7.5" rear end. 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.

        1 2006 V6 - DavidSersh48 Installation Time: Weekend


        Spent almost $1,000 on brand new parts for my differential, including these gears. Did the work myself. Came with no instructions/specifications. The gears seemed to be fairly well made, but in my experience they should come with the specifications they require. Very disappointed overall.

        Motive 4.10 gears

        I purchased these to give my mustang a little more umph. I love them especially when I am able to put my foot on it, it has a lot more get up and go that's for sure. Very nice product. The only issue is there is a slight gear whine when decelerating but that's the only issue and I'm sure after breaking them in it will go away. Otherwise a great buy, great product. Thanks AM

        Jumps straight into the power band.

        It is a great performance enhancement that I'm glad I undertook. It's like a whole new machine. My baby jumps up and goes with the press of the pedal. You won't be disappointed with this if ya throw in a BAMA tune to get it all tied into a nice li'l package. Installed this along with the Ukon LSD!

        Great for acceleration but maybe too much for me

        Great gears. Shop took about a whole day to install these. About 5-10 hours and it cost me roughly $550. The acceleration gain is highly noticeable and it completely kicks up with my Vortech V-3 Si Supercharger. I just got it installed so no issues yet but the only issue that I care about is gas mileage at highway speeds. 60-80mph and I'm up at the 3k rpms and my gas is going. If anyone is a highway cruiser then I would definitely take it into consideration of looking into the 3.73 gears other than that I'm pretty satisfied! Also it will throw off your speedometer but that's to be expected.

        When I First Started to upgrade my Car 2010 mustang v6. I Ask What Can I Do To Upgrade My Acce. My BestFriend Recommened me Gears. So I Came Here And Got These And Let Me Tell You Something. I Was Impress With How Much Acce i get in my first 3 gears. Best Experiance Ever. But Thiers One Down Side. These will Give You a Little Less Top Speed on Your Car. But Other That I Loved It. I Bought These Gears with along the Bearing Kit And 2q of Royal purple.

        5 2006 V6 - Linkin Installation Time: Weekend


        It seems the mods that have the biggest difference are power adders and gears. I ditched the freeway 3.31 gears for the 4.10's and I'm not disappointed. When combined with my nitrous, turbo, and isopropyl injection, it packs a heck of a punch.

        4.10s make a huge difference

        My pony pulls real hard now I definitely recommend these gears to anyone wanting to have a seat pinning experience on a V6 I didn't have enough cash for a posi unit but my stang still runs like a champ (Best man for differential work in the Rio Grande Valley is Johnny Gears)

        Gears are the way to go

        I had these gears installed along with a Ford Racing T-Lok. I'm still in my break in period, but the difference between these 4.10's and my stock 3.31's is really noticeable. i really get put back into my seat when i jump on it. Best mod i have done so far with the T-Lok.

        Motive Gears Are Great!!

        Got these gears along with the installation kit. Notice a major difference immediately. Just be sure to get a professional shop to install. Mine were installed by Competition Auto. Slight whine on deceleration but it's barely noticeable. Thanks AM

      5 Top Rated Questions

      I'd like to know the main difference between these 4.10 and the 3.73 gears for a 2010 v6. Which Are recommended more ?

      • The higher the gear ratio, the quicker your Mustang will reach the top end of each gear. With that being said, you also lose out on your top speed the higher the gear ratio for that same reason. So, a 4.10 will likely put more stress on your Mustang relative to the 3.73, but of course you'll get a quicker 0-60 with the 4.10s. Now, we suggest that if you have a manual and drive on the highway or similar driving, you may be better off with a 3.73. With an automatic, the overdrive feature allows less issue of stress to the engine so you can get away with 4.10s regardless if you are driving on the highway.

      If I want to put these in my 2010 V6 and I'm already running a bama custom tune, do I still need a recalibration tool or will going through bama for a new tune solve that issue?

      • BAMA will be able to tune for these gears when installed.

      Will this make 20-40 roll race times slower ? I know launch time from 0-60 is vey much improved but i havent seen many post about roll races.

      • Hi, I do not recommend using these Motive Performance Plus 4.10 Gears in a roll race because you will run out of gear pretty fast, I suggest using Motive Performance Plus 3.73 Gears Item# 21107G05 using 3.73s your power band will be longer. Here is the link
