    Features & Details

    • Superior Quality
    • CNC-Cut from 8620 Gear Steel

    Improve Overall Performance. Wake up your V8-powered Pony and get better acceleration off the line with a set of steeper gears. These high quality 4.10 gears from Motive will give your Mustang more pull off the line and get you into your power band faster for quicker quarters and lower ET's.

    Superior Construction & Precision Fit. These Motive ring and pinion 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. Unlike other brands, Motive Gears do not have a reputation for "gear whine."

    Application. This Motive Performance Plus 4.10 Ring and Pinion Gear set will fit 2010-2014 GT, BOSS and GT500 Mustangs. A master bearing kit is recommended by most installers, especially on high mileage vehicles, see drop down option above.

    Attention 2010 and newer Mustang Owners. Starting in 2010, Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. Due to this, installation 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.

      Great Bottom End Power

      First of all I installed these on a 2013 Manual GT, the car had 3,300 miles on it. The car originally had a 3:31 rear gear. I should have bought the car with the 3:73 rear gear. Mods so far are as follows - Flowmaster American Thunder Axleback, Magnaflow O/R Tru X-Pipe, Airaid CAI, SCT Tuner (93 Octane race tune), and now the 4:10 Motive gear. I'm only getting started...... I debated for two months on either installing the 3:73 or the 4:10. Some people I spoke to said 4:10 would not be to much and others said this gear would be to steep. So for you people who are trying to figure out which gear to go with, I'm going to try to help you make your decision. To start if I had it to do over again, and I might in a year or so, I would probably go with the 3:73 gear. Just because I do a lot of interstate driving at 80 mph. And at 80 mph I am running about 2800 rpm's (effects fuel milage). But if your average speed is 70 or under the 4:10 would be perfect. The take off power is awesome, it's like your car wants to be above the 3000 rpm range all the time. So the power is always ready to be unleashed. With the six speed manual transmission your not in any gear very long, this really makes the car get up to speed very quickly. As for the fuel milage - I've had these gears for 3 days (now I have been playing a little) and I seem to be losing about a 1.5 mpg. I know three days doesn't seem like enough time to tell, but I drive at least 50 miles a day. As for the whining noise some people get after installing the 4:10 gear. I have little to no noise at all. It's all in how good of a pattern set up the installer gets. I watched the installation of my gear to be sure it was done correctly. And the pattern I had was perfect. The backlash was also well within tolerance. So make sure you check around and find someone who is highly spoken of to do the install. Overall this is a very good mod for the money. The 4:10 is awesome to play with, at stoplights it a great feeling to have that power to get up and go. As long as you don't drive at a speed of 80 or above regularly this gear is perfect and even if you do it's still pretty good. Just eats up the gas. I hope this helps!!!

      Great Gears

      if you have a mustang with an 8.8 rear axle, you have to have these gears, it is NIGHT AND DAY, just from these gears alone i saw a huge increase in power all across the powerband

      go with ford racings gear(At least thats what my shop told me). These gears whine. It annoys me, if it doesnt annoy you then buy them. The 4.10 and the tune made the car so stupid fast. Just got my first ticket in them!!!! LOL. That\'s why i give the 4.10\'s a five star! Definitly needs to be first mod

      Plan First...

      These 4.10 gears from Motive were the third modification I had done to my GT. The difference in acceleration was very noticeable. One thing everyone warned me about was a drop in fuel efficiency, which I did not see. The gears allow the engine to operate at a more efficient speed, which won\'t really affect mileage if you keep your foot out of it. Another common misconception is a drop in \"top speed.\" That is totally false. Your top achievable speed will actually increase now that the engine will be operating at a slightly higher rpm. Sure, the top redline speed is lowered to 156, but unless you can run 8\'s in the 1/4 mile, you have nothing to worry about. These gears did have a little bit of whine, mostly heard when no load was placed on them (coasting). Unless you hear excessive whine (almost like a loud hum heard at all times), you have nothing to worry about. I recommend you give these gears a couple of heat/cool cycles before putting the pedal to the floor. That hardens them up. Lastly, plan things out before you get 4.10s. For an N/A Mustang, they provide a good increase in acceleration at the cost of 500 rpms. If you plan on supercharging your Mustang, I urge you to consider 3.73s. Overall these are a very good set of gears, and ideal for most Mustang owners. I recommend purchasing the differential bearing kit with these gears.

      Hands down one of the best mods you can do on a Non-PI mustang. All I can compair it to is, it feels like the car has a shot of nitrous. Once again has the best/fastest shipping times around!
