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.

Power. Performance. Personalized. The SCT Power Flash Tuner features Bama Performance custom tunes that are written specifically for your Mustang. Our tunes are based on a 19 point questionnaire to deliver the most power and performance possible for your Mustang’s modifications. All Bama Performance tunes are tested and proven on our very own in-house Dynojet 224xLC Chassis Dyno.

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 2-3 business days plus applicable shipping time. We recommend ordering other products separately to avoid delay. Some heavily modified cars are not tunable with a mail order tune. Membership in the Tunes for Life program is is valid for as long as you own the car that was originally tuned and is non-transferrable.
