Description


Improve ET's and low end torque. Are you looking to get more low end grunt off the line and lower 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 3.73 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 Ring and Pinion Gear set will fit all 1986 to 2012 V8 Mustangs including GT, Bullitt, Mach 1, Cobra and the 2011-2014 V6 Mustangs equipped with the 8.8" rear end. A master bearing kit is recommended by most installers, especially on high mileage vehicles, see drop down option above.

Attention 2010 and newer Mustang Owners. Starting in 2010 Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. Because of this you will require a new 8.8" rear gear pinion bearing (Ford part# 9L3Z-4630-A) for proper installation, please 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. 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.

    Can you say IMPROVEMEMT?

    Installed on my 03 GT. Install price was $200 trust me if you dont know what you are doing with the shims and setting the backlash have a pro install these, but lauch is much improved 2nd gear is nasty. Went to the local strip with is an 1/8 mile track and ran 9 flat with the help of the AM CAI. Killed a few Comaros in the process and isn't that what we are all after? Buy it stop reading! GO!

    3.73 2008 GT

    What gear do I get? That is the question burning through your mind, dear reader. I have not had a 4.10 in my car but putting in the 3.73 is with out a doubt a perfect match! The car is tighter on the pick up and it goes like stink! When you want it to be tame it will do that too. RPM increase at 60 mph is only about 200 RPM. Very little loss for a very big gain! I had mine installed by a good mechanic and that ran me a little over $300. A perfectly balanced gear.

    3.73 Gear Install

    I just had my 3.73's installed the other day on my 96 GT conv. MAN!!! What a difference. I would defintely recommend buying the bearing kit and the Royal Purple Max Gear oil. I did and I don't have any sort of whine, it is just very smooth, and definetly pulls much harder in 1st, 2nd, and 3rd. Thanks to AM for another perfect order!!!

    These 3:73 gears are awesome. Ford should have built mustangs with these gears instead of the whimpy 3:27\'s. Be prepared to get whiplashed while switching through gears. And if your good with the stick (manual transmission) you can burn rubber in 3rd gear too. These gears unleashed the beast within my 03 mustang they are a must have.

    THE BEST

    i was trying to decide to go 3.73 or 4.10 but 4.10 will be to much. i went for 3.73 and got them installed at a profesional shop at houston performance and woooooow big difference, i love the way my 5.0l 94 stang, pulls now 2nd 3rd and 4th even 5th gear feels like 3rd going at 40 or 50 mph very pleased. if u are thinking about 4.10 and 3.73 go for 3.73 u wouldnt regret it. i recommend

    Looked at a few gear ratios but couldnt really decide. i wanted something that would make a big difference, but i wanted it to have good street manners as well. went with the 3.73's and it was the ticket dead on. puts me in the rpm range when i need them, yet lets me cruise in 5th with an acceptable rpm range. be sure to get the install kit and you should be good to go. i did the install with a friend and was able to get it done in 4 hours; but prepare for a fight. AM was great as always, fast shipping quality product. (wish this was my 1st mod performed, huge difference over stock which was a 3.27 in my stang)
