      Hey, I'm Justin with, 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.
