Description
Improve Performance. Wake up your V6-powered pony for faster acceleration off the line with a set of 4.10 Motive Performance Plus gears. A steeper set of gears will get you into your power band faster for faster launches and more punch off the line.

Superior Construction. These Motive ring and pinon gears are CNC cut from high grade 8620 gear steel, and factory lapped for precision fit. Each set is hardness tested prior to leaving the factory to ensure the highest quality.

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 Motive Performance Plus Ring and Pinion Gear set will fit all 1999 to 2004 V6 Ford Mustangs equipped with a 7.5" rear end. A master bearing kit is recommended by most installers, especially on high mileage vehicles, see drop down option above.

Installation note. The Ring and Gear Pinion kit will require a notched cross-pin for proper installation.

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.

Will these Motive 4.10 gears fit inside this? http://www.americanmuscle.com/auburn-hp-28spline-75-lsd.html Since the Ford Racing T-Loc is no longer available, I'd like to know if these 4.10 gears will fit with the Auburn HP Series Limit Slip Differential - 28 Spline 7.5in before I plop down the cash.

  • Yes, any gears made for 7.5in differentials should work.

Gains without a posi What kind of gains in 0-60 could I get without a limited slip differential?

Moses

  • Without posi, that one tire will be spinning all day long. If u do alot of hiway driving I'd go with a 3.73. Also motive is know to have a lot of whine while driving. Go with a ford racing gear! As for gains I can't tell you an exact time. But it definitely is the biggest bang for your buck for performance mods.

    SWEET

    I had this installed with a T-Lok. After a day of driving, I still have a stupid smile i can't get rid of. American Muscle is the Best. Can't wait to get my tuner and CAI.

    Manual Tranny w/ 4.10\'s

    Now I\'ve heard that 4.10\'s with a manual transmission are a bad mix. The gears, they say, would be too short. The Facts: 1st - Pretty short, but not too short. PULLS! 2nd - Pulls like 1st did with stock gears 3rd - Surprising improvement 4th - Great for slaughtering traffic 5th - 2600rpm @ 70mph. Revs are a little high at freeway speeds, but in town, 5th is actually usable. If I did it all over again, I\'d might get 3.73\'s just because of the freeway revs, but I do NOT regret this mod. If all you\'re looking for is acceleration, 4.10\'s are the way to go.

    4.10 Gears

    The 4.10 is definitely different. It takes getting used to. Yes, it does rev higher, but that's no surprise. You get through the gears very quickly. Here's the truth. At a traffic light, when the light goes green, I have to get into 2nd gear before I cross the street. I'm in 4th gear by 40 mph. I've only had it for 4 hours so I haven't gone above 70 yet and only 2 races tonight. That's taking it easy. Can't wait till I've broken them in. Keep in mind that wasn't the only change made at the same time. Also added posi, aluminum drive shaft and Bama tune. So it's like learning to drive it all over again. I've had my car for 13 years and will always have it. Getting used to shifting much sooner is the task at hand. I've had 3.55 and 3.73 gears. 3.73 is probably more drive-able but I'll stick with the 4.10.

    awesome gears

    These gears are awesome! They dont whine, but if your gears whine, just take them back to the shop. Thats what I did and the only thing wrong was that the crush sleeve needed to be crushed a little bit more. Thanks American Muscle!

    Does the job

    Does what its supposed to, definitely more pickup from a stop. I get whine at around 1500 and around 2500 but it doesnt bother me too much.

    ACCELERATE!!!

    I had to get my gears from somewhere else because I couldn't wait for restocking but AM still has the best price with free shipping. I had to do a small grind on the cross shaft pin after setup was complete to finish up the install. motive's site states that a special cross shaft pin is needed with these gears. a grind hooked it up though. overall, great! the accelleration is awesome and there is no whining or grinding.

    its a mess but worth it to install

    Well i bought these and when i went to install them i noticed some problems. the number one problem was that the cross shaft pin absolutely has to be grinded down if you do not buy the posi trac diffriental. the ring gear is alot thicker than that of the stock 323 gears. another thing is that the recommended parts does not say anything about this. TRUST ME IT IS A MESS TO INSTALL BY YOUR SELF BUT WELL WORTH THE POWER DIFFERENCE. IT IS NICE TO SHIFT INTO FOURTH GEAR AND HEAR A BARK WITH BRAND NEW TIRES LOL AND BY THE WAY EVERY ONE THAT COMPLAINS ABOUT THE WHINING NEEDS TO CHECK THEIR BACK LASH ON THEIR CRUSH SLEEVE BECAUSE THAT IS WHAT CAUSES IT TO WHINE

    BREAKAGE

    HAD THESE AFTER I GOT BACK FROM DEPLOYMENT IN JULY OF 09 AND IN DECEMBER THEY BROKE AND TORE THE WHOLE REAR-END OUT. SO IF YOU PUT 4.10'S IN, MAKE SURE YOU PUT IN GOOD AXLES, FORD RACING PARTS, AND LUBE IT UP WITH ROYAL PURPLE OR YOU WILL BE SITTING IF YOU HAVE ANY KIND OF MAJOR MOD WORK LIKE MOTOR OR FORCED INDUCTION LIKE MYSELF
