Description
Bama Performance The Gears
The Gears

Improve ET's and Low End Torque. Installing a set of steeper rear gears is a great way to get more low end grunt off the line and lower your ET's at the same time. Ford Racing Mustang ring and pinion gears feature a super strong forged construction, CNC cut & lapped gear teeth, and a black oxide finish to resist corrosion making them perfect for street, road, or race use. More info about these gears - Here

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.

**NOTE: Programming custom tunes may take 3-4 business days. We recommend ordering other products separately to avoid delay. Heavily modified cars are not tunable with a mail order tune.

Increased HP and torque. From the factory, the manufacturer programs their vehicles to cater to the needs of the daily driver, not the performance enthusiast. After loading the custom Bama Tune on a vehicle, even a bone stock, unmodified Mustang will realize noticeable gains in HP, Torque, and Fuel Economy.

Increase your mod's potential. Factory computer settings are calibrated for the original factory components. When making performance modifications, you need to recalibrate the vehicle's computer to realize the full potential that these modifications can achieve.

Free tunes for life! Every customer that purchases a tuner is enrolled in the "Free tunes for life" program. Any time that you make additional mods to your vehicle, our team of SCT certified Bama Custom Tuners will create new tunes for you.

Custom Bama Tunes specific to your vehicle. When you order a tuner, you aren't just getting a tuner - you are getting the tuner and 3 dyno-tested custom Bama tunes:

  • Street (87-93 octane) - the street tune is designed as a daily driver program that focuses in on increasing mid-range power. It does give up a few HP at higher RPMs, but that's why there is a Performance file. Automatic vehicles are further enhanced by making adjustments to the transmission's shift points and firmness.
  • Performance (87-93 octane) - The Performance program is designed to add power at 3000 RPMs and higher, focusing more on the top end horsepower and all out performance driving. Timing, fuel and throttle response settings are slightly more aggressive than the street tune. This is a great track tune but also works well for daily drivers that are looking for a little more "get up and go" than the street tune. The automatic transmission settings are the same as in the street tune.
  • Race (91 - 93 octane) - The race tune will ensure the largest increase in vehicle performance. Using the highest grade of fuel available in your area is mandatory. This file is designed for "Race only Use" as the timing, fuel, and throttle response settings are very aggressive. in fact, the adjustments are so aggressive, that we do not recommend it for daily driving as it may cause your vehicle to try to jump out from a stop and easily spin the tires. Finally, with the automatics, we implement entirely new shift points and firmness settings to further enhance the all-out performance of the vehicle.

Nitrous (91-unleaded race gas) - Our nitrous option can be added to any of our previously mentioned tune options, but only for 91-octane unleaded fuel.

Easy to load; easy to restore. Not only are the custom tunes easy to load on your vehicle, it is just as easy to restore your factory settings. When you load your custom tune on the vehicle, the tuner automatically stores your vehicle's factory settings. To return the vehicle to its factory settings, just plug the tuner back in, select the option to restore the factory settings, and you're done.

Whats the difference? What is the difference between this kit and the kit for 35 dollars?

  • This kit comes complete with everything you need for a full rebuild: bearings, shims, crush sleeve, etc... The $35 kit is a basic kit that is the same as the more expensive version, but there are no bearings included. We highly recommend getting the complete kit and replacing all your bearings and shims at the same time to prevent any costly problems down the road. It's better to replace them all at once, rather than having to tear the car apart again just for a bearing gone bad.

  • Within the tune, we will correct the shift points when notified of a gear change such as 4.10's and the speedometer will be fixed as well.

    From 3:27 to 3:73 & now 4:10

    Hey everyone I had purchased the 3:73 last year and was amazed from the difference. Well, here I am again and I had the 4:10 installed. Woooooowwww what a difference, The car moves like a rocket. One thing though I can\'t stay in first gear to long because after 2 seconds from the take off you would have too shift into 2nd. It\'s great I tell you, Just remember for every one gear you upgrade, it increases your rpm\'s by 200, but aslong as you have a stick, your 5th or 6th gear would bring your rpm\'s down to about 1400. This gear is truly a must have.

    Pay for it now

    Even if you send the car to the shop to get it rebuild, you are much better off buying this kit then paying for parts. I was quoted a $900 installation + parts for redoing my rear gears. So I purchased the parts and lube here in American Muscle and only paid for labor which was only $360, so I ended up saving $275.

    FRPP 4.10 Gears for 2001 Mustang GT

    I love these gears! They really wake up the car. I got decent gas mileage 2! I have a 2001 Mustang GT with the AT and it was running 2800 rpms at 75 mph. That equalled out to 22 mpg not too shabby for the performance gain. The LT1 Camaro I ran hated them since he did see the stangs taillights!! Would reccommend these to anyone wanting to drag their car.

    2005 GT 5sp

    These offer a great "bang for the buck". They work great with a 5 speed, and are NOT too much gear. I did alot of research before pulling the trigger on these. Seems like there was always some bunk-hole saying "don't do 4.10's your top end will be 50mph and you will get 4mpg!" Hogwash. There is a 400 RPM increase in 5th gear @ 70mph over the stock 3.55's. Acceleration in ALL gears is improved. The car will now pull 5th much easier and is out of "drone" range while cruising. My MPG's around town/mixed driving improved by about 1mpg, while highway MPG dropped by about 1. You will need to have a handheld tuner to adjust the spedo for the new gears or else your spedo will be off. I had them installed at a shop for $300. When installed properly, these gears make NO noise. Ford really should make these an option in addition to 3.73's.

    Don't Fear the Gear

    Just as the title says. I was afraid at first to put such a steep gear into my daily driver (05 GT). After the install no regrets what-so-ever. 80 mph 3k, 70 mph 2600 rpm. This should be the very first mod to every mustang period. Thanks American Muscle!

    Must Have

    bought these along with 3.73 gears for my 06 GT, if your installing new gears you NEEEEDD this kit. NEVER redo a rear end reusing the original bearings and bolts.I had ford do the install and if i bought the same bearings and bolts through them it woulda been $250 extra. trust me these are so worth it and assurance that NOTHING can go wrong if you do the install correctly

    2008 GT/CS

    i have numerous bolt-ons but the 4.10's are by far my best investment. It wakes up your car when you want it to but isn's too much for a daily driver. The description claims to reduce your gas mileage but mine increased somehow, which makes no sense considering i accelerate a lot faster and a lot more often. I recommend having them installed by a shop. i have a buddy who is a mechanic and he had trouble doing some at his work and had to call over help. The highway driving isn't bad. The car will hum a lot louder on the highway but if you punch it'll throw you back. First gear is pretty powerful, Second is great, and once you hit third at full throttle you are happy you bought them! I strongly recommend these especially if you want to mess around with other mustangs because they just cant keep up once you have the new gears.

    did what it was supposed to...

    well, its a bearing kit- no frills to it i guess. I wish there had been a larger selection of new shims to use- there seemed to be only 2 sizes if i remember correctly, so you have to use a larger stack of shims, as opposed to a few thicker shims... not that it really makes a diference i guess. it also comes with a kick a$$ motive bearing sticker for your tool box... oh, and the directions for how to re seal the cover were wrong... My instructions are to take that gasket in your hand, and sling it into the front yard as hard as you can- then go get some good rtv and put a bead on the case... those gaskets are worthless...
