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.

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. Some heavily modified cars are not tunable with a mail order tune. Click for details. Tunes for Life membership is is valid for as long as you own the car that was originally tuned and is non-transferrable.

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.
