        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. This Ford Racing Ring and Pinion Gears are perfect for street, road, or race use.

        Complete Kit. This Ford Racing Gear and Installation Kit comes complete with all the components needed to swap out your ring and pinion gear. It includes Ring gear, Pinion gear, inner rear gear pinion bearing, 1 bottle of Friction Modifier, 2 bottles of 75w140 Gear Oil, gaskets, seals, shims, bearings and all the required hardware.

        Legendary Ford Racing Quality. When you're adding performance parts to your Pony, you can't go wrong by installing parts from the folks that know it best. Ford Racing's legendary quality ensures years of hassle-free use.

        Recommended Upgrade. Changing the rear axle gear ratio will throw off the calibration of your Mustangs speedometer, but a Ford Racing Speedometer Recalibration Tool or a Bama SF4/X4 Power Flash Tuner is a quick and easy way to fix this issue.

        Application. This Ford Racing 4.10 Rear Gear and Installation Kit is designed for use with 8.8in solid rear axle equipped Mustangs, including the 2005-2014 GT, Bullitt, BOSS, Shelby GT500 and 2011-2014 V6 models.

        Application Note: Does not fit 2013 Boss or 2013-2014 Shelby GT500 Mustangs with axle codes S-215-D and S-219-D.

        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.

        Do i need a tune with these 4.10 gears? (2012 v6 manual)

        • A tune will not be required with the Ford Performance 4.10 Gears and Install Kit (10-14 V8; 11-14 V6), however your speedometer will be off. With a custom tune this will correct the speedometer.

        My 2013 gt is sprayed. I broke my driveshaft and ruined the rear end on the drag strip last night. Will these gears be good for 1/8th mile and 1/4th with nitrous.

        • The Ford Performance 4.10 Gears and Install Kit is definitely a good upgrade over the stock gears. For what you are using these with I would recommend the Ford Performance Traction - LOK Rebuild Kit w/ Carbon Discs Item #50092(http://www.americanmuscle.com/ford-88-traclok-kit.html) to go along with this kit to help make it stronger.

          4.10 Gear Kit

          Just a quick reference on this kit. I have a 2013 v6 automatic. I am adding some nice mods slowly for power and torque. These gears are the first thing after you CAI you should purchase. I had a local gear shop install this kit along with a BRAND NEW Traction Lock with Carbon Discs. Not the rebuild kit. Took the shop about 4 hours at a cost of $450. They have strict break in they recommend which is 1,000 miles. After 700 miles they recommend bringing it back in to replace the new Royal Purple with new. So I am going to lay low on them as prescribed. Yet I can tell that right off the top you can feel the difference just moderately driving it. Very happy with this changeout. Have yours installed right. This is not an easy job and certainly not for an amateur to try.

          20 inch wheels/this gear,perfect street ratio

          These gears put the power band of my supercharger right in time. I personally think these are perfect, not too steep, great at the strip and still cruise 75mph at under 3000rpm

          Good bump in acceleration

          Had these installed for about $400 very slight hum above 60 mph. In a 6 speed card you're looking at about 3000 rpm to go 80 mph. Good quality kit and a significant boost to acceleration. You need to plan for some rear suspension upgrades to help with traction.

          Great choice

          I was on the fence between the 4.10 and the 3.73 glad i chose the 4.10 gas millage changed by a 0.4 mile difference took a while to install with no rear end experience but the PDF guide on American Muscle had all the information i needed for a good install. would not recommend installing on jack stands because getting the correct preload on the pinion nut is difficult with no clearance for leverage. but overall the performance gains are totally worth the hassle!

          Really woke the car up. Super fun to drive now on and off highway. I have a 6 speed. First gear is not totally unusable but very close. Only 200 miles on them so still breaking them in. No noise so far. Shop install.

          I chose to purchase the entire kit instead of the gears alone and it was a great decision. I combined it with a new toque converter and there is definitely a difference. I would greatly recommend it for anyone that wants to that 1/4mile tome down.

          2015 5.0 COYOTE GT/CS

          Switch from a 3.31 rear to the 4.10 the 4.10 pulls harder down low as expected. before when launching the car from a dig on the street the car would lag till I hit 3k where the power comes on, now it goes right into the power and the lag is almost gone. the install kit comes with a new pinion bearing so you will not need to order a separate one, and the two quarts will not completely fill the axle 4 oz. short. definitely would by again.

          '11 Automatic GT 4.10s

          These 4.10s give you a great feel out of the hole if you can hook up. The quality is good(no noise), and would recommend a shop install. If you have an automatic 11-14 GT though.. These aren't that great for us. Yes, you get the sensation and feel of a faster accelerating car, but the fact is your ETs stay the same or suffer with these gears with how short the auto 1st gear is(why AM suggested these is beyond me). Went to a drive train specialist who works on Fords almost exclusively and he recommended the 3.31s/higher stall torque converter for my auto and my ETs were slightly better with just the 3.31 swap alone, and assume they will improve drastically with a TC.

          Perfect gears for my 6 speed gear box SC Mustang and didn't affect the top end performance either, except it gets there allot quicker. Very street-able gear that's fun to drive anywhere. The best bang for the buck!
