Description
Improve ET's And Low End Torque. Are you looking to get more low end grunt off the line and lower your 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 4.10 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 Ford Racing Speedometer Recalibration Tool is an inexpensive way to fix this issue.

Application. This Ford Racing 4.10 Ring and Pinion Gear set will fit all 2005 to 2010 V6 Mustang models 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.

Will this potentially hurt my rear axel? I'd really like the acceleration of 4.10s in my 2006 4.0, but I would like to know if this might hurt my 7.5 rear end in the long run.

  • These gears are designed for your 7.5" rear so you don't have to worry about hurting your rear by installing them. They are a great upgrade, but do make sure to get the rear installation and bearing kit, the gear oil and a new tune to correct your speedometer! After that, enjoy your new mod!

What kind of increase should I expect on the quarter mile? Just wanted to see what kind of performance boost this will give over the stock gears and the 3.37? How much of an increase can I expect to see on my ET over the stock gears? How much faster are these than the 3.73's? And what can I expect my rpm's to be at if I am coasting at 80mph? Lastly, how much mpg decrease are you guys seeing with these?

    Awesome Gears

    When I bought my mustang I was on a tight budget for my monthly payment, so I bought a 2008 v6 pony package to save a few thousand dollars over the GT. I am a speed freak and I kick myself everyday for not having spent the little extra money. But that was before I found out about American Muscle. I have had the modding bug ever since I put on the BBK CAI. Now my goal is to make my v6 into the most badass 4.0l possible, and these gears are doing just that. I debated forever between the 3.73's and these gears and ultimately I decided the added acceleration of the 4.10's was worth the gas price and highway revs. I'm about 300 miles deep in my "break-in period" and I took it easy on them for about 100 miles. I have full confidence in these gears and my rear axle so I have beat them up a bit with some absolutely brutal 0-60 runs. They are amazing. My mustang is a daily driver so for all of you that are the same way here are some facts: 1st- Short, torquey and pulls 2nd- Decent length and pulls even harder 3rd- I slaughter people on the on ramps now 4th- Not as useable in town anymore still pulls- at 49 mph you are now at 3,000 rpm (use to be at 3,000 rpm at like 70!) 5th- Becomes a necessity to use- almost like stock 4th- at 49 mph you are at 1,500 rpm now 6th- Need a 6th gear for the highway ; ) Yeah like I said I'm really disappointed with 4th gear. I can now use it in my neighborhood but not much else, 5th is now 4th. Revs are high with the 4.10's but I'd pretty much always be flooring it anyway. The gears had to be shaved down slightly in order to get a perfect fit, I've heard a new LSD fixes that problem but I did not install one with these. My shop did it for $428 and it took them about 5 hours. Overall it is a great product and the average ricer won't touch you!

    This mod really transforms your 4.0 stang!

    These gears make a BIG! difference on your acceleration from a dig and less than 60mph punch. I have it installed on a 2008 4.0L Automatic. My gas mileage does suffer on highway considering the RPM's are about 3000 at 70mph, but city is about the same. They where installed at my local Mustang Racing garage for $250. I only experience vibration at speeds 84-86mph but now that my cars got ~800mi since install, the vibration is starting to go away. At time of writing this review I have 93 octane performance tune, BBK CIA, Port&Polished TB, X-Pipe W/ Dual exhaust, Ford 4.10 gears, NGK Iridium IX plugs w/ Taylor wires, 275/40R17 tires/wheels. I installed all these mods one at a time and the gears made the biggest noticeable gain in acceleration. I'm not running T-lock (posi), but with 275wide tires I don't have issues with excessive burnout from launch, but be aware, punching it from a roll is going to put you back in your seat and spill your drink ;)

    woke up my full bolt on 4.0 2010 v6 !!!

    i have to say that i didn't expect such a huge increase in performance especially off the line ! i got these gears and and auburn differential and not only do both tires spin now but the amount of power off the line is crazy now. i highly recommend these gears but i will say that if top speed is your thing that these gears lowered my top speed by about 5mph not that big of a deal to me for a ton of low end torque lol ! to anybody who buys these or is thinking about it trust me u are making a good choice !! =) these gears pull hard out the hole and hard out of a turn wut more can u ask for

    Torque!!!

    Love these gears worth losing the little mpg and 5 mph top speed! Had the ford store install with master mechanic because I know if there's a problem I'm takin care of. Also read too many bad reviews for all the gear shops! 625 to install but peace of mind is definitely worth it!

    Best mod for v6 Mustangs

    Makes the car drive much better. Even makes the auto transmission shift better. Big difference on the freeway. If you like to cruise over 70, be prepared to see rpm's around 2800+. A limited slip is a must for wet roads with these gears. All trans gears, especially 4th and 5th, pull much harder now. To summarize: 1. Over 70 mph=3.73's 2. Around town and two lane highways=4.10's 3. Only buy if you like smiling while driving.

    Awesome performance gain!!!

    If you're looking for a huge difference in performance, then these 4.10 gears are a must! I've already had 4.10 gears installed before, but had to replace them due to an improper install, so I recommend a reputable shop that specializes in differentials. Though it's advised not to press on the pedal all the way until the gears break in, I've been able to test them out on the previous 4.10 gears I've had installed, and all I can say is that they do make a huge difference in acceleration!. There is no whine at all, and also depends on the install. Accompanied by the limited slip differential and a custom tune from American Muscle, you'll be satisfied with the results. American Muscle has been great with the customer service as always. Get the gears!!!

    4.10s for my 4.0

    The 4.10s in my 4.0 5 speed are awesome. 1st gear is short but pulls hard, and lights em shifting to 2nd. The highway revs are a bit high but it's well worth it, seems like its in its sweet spot. Worried about losing top end, forget about it. These gears will allow you to pull hard in 5th. Faster then you'd ever get with 3.31s for the amout of power the car makes. I recommend them to anyone thinking of purchasing. Just get them, you won't be disappointed.

    4.10 for city

    if you get this remember that while it will increase your acceleration it will lower your top speed significantly. i had hit 120 mph with out any issues using the stock 3.31 gear, but after installing the gear i am now getting 107 mph and some vibrations (possibly due to need a few more adjustments and parts) at the top end. personally i am wary about changing programming to increase the top speed, but right now i am considering 3.73 to increase the top speed

    Fantastic product!

    At first I didn't know what gear ratio to go with. I knew I wanted better acceleration but I was torn between the 3:73's and the 4:10's. Let me tell you, I'm sure glad I picked the 4:10's! The acceleration it amazing! I can even make the wheels cherp going into second! Great product and a must have for any serious motor enthusiast!
