    Review & Install Video

    Stephanie: Hey, guys. Stephanie with americanmuscle.com, and this is my review on McLeod's 8 Bolt Lightened Steel Flywheel that's going to work for '96 to '04 Cobras and Mach 1s, '99 to mid-'01 GTs, and '11 to '14 GT and Boss Mustangs. This 8 Bolt Lightened Flywheel from McLeod is going to be for Mustang owners that are replacing their clutch and are looking to replace instead of resurface their flywheel as well. So your two options when you're replacing your clutch are either resurface your old flywheel or go for a new one. And honestly, while you can resurface, I really think it's best to go with a new flywheel by the time you're done paying for resurfacing anyways. Plus the flywheel's really pretty important to the clutch's functioning and can dictate how well it will perform and for how long. So if you're springing for a new clutch anyways, why not give it the best components to do its job to the best of its abilities? So a bit feature about this flywheel is that it's lightened, but I just wanted to address some things with this here. Having a lighter flywheel isn't going to change the actual horsepower of the engine, but if we think of it as rotating mass, in order to accelerate, all of the rotating mass needs to be moved, like your wheels, your driveshaft, your flywheel, all of that. The more that rotating weight is, the more power and RPMs it will take to move those items and get the car moving. The less power that you car needs to speed up the flywheel, the more power available to speed up everything else. So this flywheel isn't going to add horsepower, but it will leave more available horsepower to accelerate the car and get it off the line per se. So, this is a steel flywheel that's going to weigh 20 pounds. This is lighter than the factory flywheel, but it isn't going to be as light as an aluminum flywheel. But when you're shopping for a flywheel and clutch, you really need to understand what you're looking for from these components. There are tradeoffs between going with a lighter or slightly heavier flywheel, so lighter isn't always better. It just depends on the situation. A heavier flywheel is going to be smoother overall, smoother at takeoff, smoother at idle and cruising, but as I explained earlier, a heavier flywheel will mean slower acceleration. This is why this steel flywheel is a good option for street cars and some recreational racing and in general, high performance applications that can see some spirited driving. If you have a car that still sees some street time, but you really want the highest performance possible, then you might want an aluminum flywheel instead as long as your budget agrees with that. Now, getting into a little bit more detail about this one here, it does have 164 teeth on the ring gear. It's neutrally balanced, and has that 8 bolt main pattern. So if you're shopping for a '99 to mid-'01 GT, just check your production date since the mid-'01 has a production date of June of '01. And this is SFI certified for you guys that are planning on using this in high performance or drag racing applications. As far as price goes, you're looking at between $200 and $300 for this flywheel which, like I mentioned before, is less than an aluminum flywheel with cost, and if we compare it to other steel flywheels, we will see that it's on the less expensive side there too even though it's coming from a manufacturer with a name like McLeod. When it comes to the install, it is going to be time consuming, and I would assume that you're going to be replacing your clutch with a flywheel, so we can combine it all into one. I will say that if you haven't really done anything like this before, then it wouldn't be a bad idea to take everything to a shop for this one unless you have someone in the know helping you out. I'll call this one a three out of three wrenches on the difficulty meter, and you're probably looking at about four hours' time if you do decide to tackle this yourself. If you do choose to do this yourself, I would really recommend trying to gain access to a lift. You're obviously going to be dropping your trans, driveshaft and exhaust, so performing this on jack stands could be a little bit difficult and a helping hand with this install could go a long way. You'll need a small range of different socket sizes here and some other miscellaneous tools, but nothing out of the ordinary. Just make sure to have a torque wrench though because you really should be torquing down to spec in cases like this one here. Lastly, just as a side note, don't forget about that clutch break in period no matter who is installing the clutch. Wrapping things up here, the McLeod Lightened Steel Flywheel is a good middle-of-the-road compromise between the heavy stock flywheel and an aluminum flywheel. It's a good option for owners that are looking to keep some of the energy contained in the drivetrain and have a good street driving experience. As always, check this thing out online and see what you think for yourself. I'm Stephanie, and for all things Mustang, keep it right here at americanmuscle.com.

    Peace of Mind. When replacing or upgrading your Mustang's clutch you have two options, resurfacing your old stock flywheel, or getting a brand new flywheel. A new flywheel is a much better choice than resurfacing, as it will dictate how well your new clutch will perform, as well as how long it will last.

    Steel Construction. Manufactured from steel for extra strength, this McLeod Flywheel features a ring gear of 164 teeth, an engine balance of 0 oz, and an eight bolt main pattern. Steel flywheels are perfect for street and race applications where off the line acceleration is desired.

    SFI Certified. If you're using this flywheel in high performance or racing applications, SFI Certification is critical so you can run your Pony at the track or strip. And it's great for peace of mind even in a daily driver - at higher RPMs, stock cast flywheels have been known to explode.

    Application. This McLeod Flywheel fits the 1999-Mid 2001 GT, 1996-2004 Cobra, 2003-2004 Mach 1, 2011-2014 GT and 2012-2013 Boss 302 Mustangs with an eight bolt main. This is the perfect companion to your new McLeod Clutch.

    Technical Note. This McLeod flywheel has an 8 bolt main that is found in the 1999-mid 01 Mustang GT's with production date ending on 06/01, 1996-2004 Mustang Cobra's, 2003-2004 Mach 1's, 2011-2014 GT's and 2012-2013 Boss 302.

    Please Note. Romeo built engines have 6 bolt cranks and Windsor built engines have 8 bolt cranks. If the 8th character in the VIN is an "X" its a Windsor block, if the 8th character in the VIN is a "W" it is a Romeo block. There is an exception to that rule as the 2001 Bullitt Edition Mustang feature a Romeo built engine. If unsure please check with your Ford dealer to determine if you have a 6 or an 8 bolt main.

    Will it work fine with a stock oem clutch? Or do I have to have a McLeod clutch?

    Jon

    • For the best functionality of the McLeod Lightened Steel Flywheel, we would highly recommend the use of a McLeod clutch. The stock clutch has successfully worked in some cases, however, not all fit 100%.

    what is better lightened steel or aluminum and what are the differences between them. i making a coyote swap with stage 3 cams COYOTE swap

    JesusG

    • The differences between the lightened steel and the aluminum flywheels is that the aluminum flywheels are only for racing mods. The lightened steel would work if this is a street car regardless of the Coyote swap with Comp Cams Stage 3 cams installed.

    • The McLeod Lightened Steel Flywheel would work with the Exedy clutch, however it is recommended to use an Exedy flywheel. The dowel pins should be able to be used with this flywheel.

      The more you know

      Some things not covered in the video ... For street and light strip use, a flywheel has to be heavy enough to get a car off of the line. Being only one pound lighter than stock for '11-'14 GTs, this has a subtle improvement in acceleration and still has enough mass for stock geared cars. Note that total mass isn't the only thing: The further out from the center the mass is removed, the greater its effect on reducing flywheel inertia. This one has the weight removed fairly far out so it performs better than just the loss of one pound would suggest. If you have 3:55 or lower (numerically higher) gears then the even lighter chrome-moly flywheel will de/accelerate even quicker and still get the car moving off of the line. This also improves how quickly the engine bleeds RPM getting to the next gear for faster shifts, and reduces transmission synchronizer wear. Ford recommends always using new bolts, though after inspecting them I've had good luck using the originals with adding blue thread locker. Can't go wrong with new Ford or ARPs though.

      Great grip, great quality

      Bought this to go with the RST clutch. Great driveability, can definitely tell a difference from the stock flywheel. No more bucking in lower RPMs and it takes less throttle to get off the line due to increased mass.

      For 11-14 GT's this is not really lighter

      So the weight of this unit is 21lb according to AM, the stock 2011-2014 5.0 GT Flywheel is 22lbs so this is one pound lighter... I really wish that was clearly stated as I would have bought the Chromoly option. I was worried I would remove to much weight over stock so I went for this unit. But when I got it and flt how much it weighed it became very clear this unit was not really lighter next to the stock unit. I would recommend the unit for those who want a new flywheel as it does seem to be a quality piece and allows you to set the dowel pin locations for most any clutch setup. But if you really want a weight savings but don't want to go full on race light aluminum go with the Chromoly unit for the new 5.0 models.

      Allows the engine to rev faster. Pulls harder. However, there is a harmonic vibration at points in the RPMs that the flywheel does not dampen. I believe this is a problem with the new flat crank engine in the Shelby 350. ( light flywheel ) and vibration. I will follow this to see if it changes or becomes a problem.
