Description
See our 2011 GT Project Car Now

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 4.10 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.

The 4.10's have it

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.

    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.

    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!

    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.

    Great for Manual!!

    First of alll- I would have been disappointed with anything less that 4.10's matched with my T45R. They stopped my car from just making a lot of noise and made it pull nicely in any gear. Performance and Traction- With my 275 Tires w/ Maximum Motorsports Lower and FRPP Upper control arms really breaking loose usually has to be intentional.... and trust me its nice to only go all "dukes of hazard" if you meant to do so. But for the serious drag racers reading this, some drag radials are recommended to really hook and clock some good 60's. I say that because vs. stock gears I didn't see any time off my 1/8mile(just a few more mph on the speedo). They may not unintentionally smoke the tiers on the street but they can be tricky to hook when every tenth is precious. MPG and RPM's- Well I don't drive a lot of highway and have actually scene and slight mpg boost on average. If I do go on the highway and do a few 4th gear pulls and go like 70-80mpg the whole time I can pretty much watch the fuel gauge drop to "E". But if you can cruise below 65 (2600+/- RPM) than its not too bad for local stuff.
