Hey, I'm Justin with AmericanMuscle.com, and this is our acceleration pack Bolt-On Build Up for all 94-98 Mustang GTs. Acceleration is the sum of a couple different parts: power, gearing, grip, and of course, driver. And that's what we're going to be addressing here in our '98 GT and our acceleration pack with one exception, the driver. Now, the parts we have lined up will not only help the car accelerate faster, but its also going to help me, the driver, get the car out of the hole and through the gears as quickly as possible. Now before we go nuts bolting everything up, lets get our GT out of the shop and do a quick 0-60 run, just to see where it stands now. Now before we bolt everything up we want to get a quick baseline 0-60 run down, just to see where the car stands now. We're going to do this using our wireless ITSX tuner, and my iPhone, should give us a good idea of where we stand. So, hit start, hold on. Alright, looks like we just clicked off a 7 second flat 0-60 run here with our '98 GT, which isn't too bad, but honestly, we can do better. So, we're going to get the car back in the shop, talk a little bit more about what we have in store for our '98, and then get it installed. Now, when you think of all-out acceleration, what's one of the first parts that come to mind. Well, if you answered gears, then then you're right on the money, at least here with our build. We went with a set of Ford Racing 4.10 gears, and why not since we're looking for maximum acceleration, while still maintaining great street-ability. Now, from the factories, the SN-95s came equipped with anything from a 2.73 rear, all the way to a 3.27, so making the big step up to a set of 4.10s is really going to be the shot in the arm our GT needed to get out of the hole, and on its way to faster acceleration. The next 3 parts all revolve around our shifting experience, and getting that power down to the ground. First up, we went with Exedy's Mach 350 Stage 1 Clutch. Now this clutch is more than capable of power our GT's putting out now, and we have room to grow, just in case we want to experiment with nitrous, or different power routers, down the road. This next part may not be as important as our gears per se, when it comes to all-out acceleration, but it's just as important, especially on our older car here. I'm referring to this Clutch Adjuster Kit, now besides offering a full range of adjustment for your factory clutch pedal engagement, it's also going to beef up a weak link in your factory clutch cable, namely that cheap plastic factory clutch quadrant. Now this plastic part has been known to flex, or even break under hard shifts, and we all know there's no better to kill your acceleration than a missed shift. By replacing those cheap plastic parts with these hardcore billet pieces, and tossing in a brand new clutch cable, well, we're halfway on our way to a better shifting experience. The second part of that equation should be pretty obvious to just about any SN-95 owner. We replaced our factory, schoolbus style shifter here in our SN-95 with this Short Throw unit from SR Performance. Not only will this reduce our throws by about 30-40%, but it's also going to clean up the entire shifting experience, taking all the sloppiness out of our stock shifter, which is going to make it a lot easier for me to bang through the gears, when we're doing a hard pull. All this for a price that's very hard to beat. With our quickshift goodies in place, the grip of the clutch, and those gears, we should be well on our way to some lower ET's off the line. I guess there's really only one way to find out, so let's get our GT out of the shop one more time, do another blast to 60, and see if we improved our times. Alright, so it looks like we just clicked off a 6.3 0-60 run, with our acceleration pack installed. That's nearly a full second difference over our baseline times, and it's just proof that our acceleration pack is doing a great job. I mean, the clutch was grabbing hard off the line, and we were really rolling through those gears with the SR Performance Shifter. So that wraps it up here with our acceleration pack for the 94-98 GT. Be sure to check out some of our other Bolt-On Build-Ups as well, where we work on our appearance, and our handling.

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 new Speedometer Gear is an inexpensive way to fix this issue.

Application. This Ford Racing Ring and Pinion Gear set will fit all 1994 to 1998 V8 Mustangs including the GT and Cobra models. A master bearing kit is recommended by most installers, especially on high mileage vehicles, 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.

What speedometer gear will i need? I am looking to upgrade my manual '98 Mustang GT's stock gears to the 4.10 gears. What speedometer gear would I need to get? Thanks.

  • You will need a calibration device like a Ford Racing M4209ADPTAC. I have installed these on several cars to adjust for different gears I suggest the optional under hood install of the box.

  • Your 1996 manual GT has an 8 tooth drive gear. Upgrading to the 4.10 gears would require you to swap both your drive gear and your speedo gear. You would now need a 7 tooth drive gear and a 23 tooth speedo gear. Hope this helps!

What will this do to the gas mileage on my '95 5.0? Will my gas mileage get worse?

JoRdAn96

  • If you do a lot of highway driving, that's where you will notice the difference. The higher gear ratio will have a little but higher rpm at different speeds. Example: with stock gears at 55 mph you might be at 3000 rpms but with the 4.10 you might be at 3500 rpms( don't quote me on the numbers just doing a for instance)

Do I need to buy the installation kit and bearing kit or just the installation kit? I was looking to buy some gears sometime soon and I am not sure if I need to buy the installation kit and bearing kit or just the installation kit? I currently have 2.73s in my car and they are starting to whine, I'm not sure if any of that would make a difference. Also could you explain your answer? Like why do I need the bearing kit (if needed) and if its not need why would I need it? Thanks!

fandroid

  • You'd want to purchase the Complete Installation and Bearing Kit. It will come with everything you need to replace while upgrading your gears. Since your Mustang is 17 years old, your current shims, bearings, etc... are worn out and that could also be the cause of your gear whine. The complete kit is also cheap insurance while doing a gear upgrade. You wouldn't want to go through all the trouble of installing new gears just to have a single bearing go bad shortly thereafter, causing you to uninstall everything a second time and put you at risk of that (1) bearing damaging other parts of the ring and pinion. Hope this helps to answer your question! Don't hesitate to contact us if you have any other concerns!

    Awesome!!!

    Only reason I gave these gears 4 stars is because I haven't had the chance to go to the track yet. My stock auto 98 gt spins through first gear now. Before the gears it runs 14.3 in 1/4 mile. Should run 13's now. Anyone that's debating going with 4.10 or 3.73 go with 4.10 totally worth it. If you have a 98 or earlier mustang I would recommend getting a new trans gear for the speedo.

    MUST HAVE!!

    These gears are the best thing I could imagine buying! I've had them in a week, and there is a night and day difference! The car actually launches without having to rev up and drop clutch. And I predict better mpg's because I now cruise 45mph in 4th at 2200 rather than third at 3000. First is gone too quick and second and third go pretty quick too, but the acceleration in third and fourth will blow you mind! I highly recommend this product! And as always, American Muscle got the parts to me fast!

    Had both 3.73 and 4.10's

    Well to start off, these will def. help your acceleration. Im thinking I will go back to the 3.73's because top end is totally lost and at 70 im running 2500rpm+ with these and mpg was def. noticeable with these 4.10's, but they are fun in the city...there just not that great on the highway...probably helps also if you have a 6spd and not a 5 like mine.

I was had to laugh when we hit 70 and he was over a car length behind me.and all i have is an offroad h-pipe and exhuast. He will still beat me from a rolling start but he doest pull away that hard any more.im not saying you can beat a z28 becuase he was gonna catch up but you will launch hard enough to make it hard for him to I have a 1998 gt auto NEW 255 tires

It breaks the tires loose in second gear just with throttle, Plus the engine sounds awesome in every gear all the time. I eat up camaro\'s and firebirds now..haha

    Rear end build

    I've got a 98 v6 that for me doesnt put out much at all so i decided to do a massive build because the car has sentimental value to me, I've started with a rear end swap out of a 98gt and knew that new gearing was essential. the acceleration I got from this swap was night and day compared to the wimpy 7.5 with 2.73 gears making it feel like a actual muscle car. I had my rear 255/50/18s chirping and the lack of a one tire fire is so nice. I cannot wait to continue the build and get a crate engine dropped in to really unlock these gears potential. thanks AM

    If you have a 96 or newer modular engine mustang then you don't need waste your money on anything less than a 4:10! This gear is a wake up call for our engines and is what Ford should have installed from the factory.

Gas mileage is the same as before or better, but I havent noticed bad gas mileage at all. Acceleration is a monster. 3rd gear on the freeway is the craziest, and 4th feels like 3rd now. If you are serious about your Mustang, this is it. You wont regret it.
