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

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.

I’m Justin with AmericanMuscle.com, and this is our acceleration pack bolt on build up for all 99-04 Mustang GTs. The focus of this pack is of course acceleration, but in order to accelerate faster you need traction, and lots of it. That’s why the majority of the parts used for our build today are focused on getting us off the line much quicker, ultimately resulting in faster acceleration. But before we go over all the parts we have in store for our 2000 GT here, let’s get it out of the shop and do a quick 0-60 baseline run, just to see where we stand now. Alright, before we go installing all of our parts for the acceleration pack, we’re going to do a baseline 0-60 run, using our iTSX wireless tuner and my iPad here, just to see where the car stands now, so hit start and here we go. Alright so it looks like we just clicked off a 6.66 0-60 time with our automatic 2000 GT, which is pretty average for this model car. Now we’re going to take our car back into the shop, talk a little bit more about some of the parts we have in store, and get them installed. Since traction is the theme of the day, what better way to get more of it, than by using a set of these NITTO NT555R Drag Radials, those large tread blocks paired with that real soft compound is going to give us a ton of grip both on the street and at the strip, and should really help our GT get off the line. To further help our GT hook we decided to go with some vital suspension components from QA1, starting with these box style rear lower control arms, these bars are a variation of the classic traction bar design, and basically help keep the rear axle from moving around under load, and especially on hard launches, eliminating any excessive wheel hop. We also decided to go with a set of these QA1 adjustable rear upper control arms, that are fully adjustable while still on the car. These are going to be key to adjusting our pinion angle which is not only important for traction, but also for driveline smoothness. These are really going to help firm up the rear end of the car, and eliminate any side to side sloppiness or wiggle, making the car track a lot straighter, and just making for an overall better driving experience. Moving away from our traction and getting into another big contributing factor to our acceleration, that’s right our gearing. From the factory, our automatic 2000 GT came with 3.27 gears, which is pretty weak for acceleration. That’s where these Ford Racing 4.10 gears come into play, simply put, that shorter gear ratio is going to help our car accelerate faster. Quite frankly, I’m quite anxious to see how it’s going to wake up our 2 valve motor. So now that you know what we have in store for our GT, we’re going to hand the car over to the crew and get everything installed, after they’re all done we’re going to take our GT back out on the street, just to see how it behaves on the road, and to see if we’ve improved on our 0-60 time. Alright so we’re out here on the street with our 2000 GT, we just had the acceleration pack installed by the guys back at the shop, and we’re just cruising, I mean the car is very mild mannered, we’re in overdrive, you’d never be able to tell there’s gears in the car, until you do a little squeeze on the throttle, and man does it go. It goes, it goes, and it hooks hard too. I mean we didn’t even have a chance to heat cycle the tires there and it just dead hooked on the street. Car is a little stiffer in the rear, that’s attributed to the stiffer bushings in both the QA1 lower and upper control arms, but that’s going to be a good thing, that’s going to help keep the car straight, going down the track, it’s also going to reduce our wheel hop as well, and overall just improve our acceleration. So now we’ve had the chance to drive the car around on the street a little bit, see how it reacts in everyday situations, we’re going to put it to the ultimate test, get it back to the shop, do a hard launch, and see if these parts work in lowering our 0-60 time. Alright, so we just finished up our second 0-60 run, and we just clicked off a 5.09 second 0-60, that’s over half a second off our baseline number, so it’s easy to see our acceleration pack is doing its job, and I’ve got to admit, those radials definitely helped us hook on the pavement. So that does it for the acceleration pack, be sure to check out our other 99-04 bolt on build ups where we make our GT handle a bit better, we give it some more power, and dress it up a little bit.

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

ncstang06

  • 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.

    I have to agree with Zack from Denver. I did the same deal and wow- what a difference! The 4.10's pick up the front end and just wanna go. If you're on the fence with 3.73's, definitely do the 4.10's. I thought it would be too much gear but it's perfect

    Review from Motive Rear End Installation and Bearing Kit - 8.8 in. (86-14 V8; 11-14 V6)

    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.

    Review from Ford Racing 4.10 Gears (86-14 V8; 11-14 V6)

    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.

    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

    Review from Ford Racing 4.10 Gears (86-14 V8; 11-14 V6)

    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.
