Hey Justin with AmericanMuscle.com here and welcome to my detailed breakdown of the Exedy Lightweight Racing Flywheel available for all 96 and newer Mustang GTs. Exedy is no doubt one of the biggest and most trusted names in stock and performance clutches and flywheels. They are one of the biggest OEM manufacturers of clutches and flywheels, and their support for the aftermarket is just as big. If you want to learn more about Exedy’s lineup of clutches, flywheels and clutch accessories, all you have to do is simply click the link below to head back to AmericanMuscle.com. So why would you want to go with a lightweight flywheel like this Exedy here? Well, whenever you’re upgrading your clutch, we strongly recommend upgrading your flywheel as well for a number of different reasons. The most obvious reason, it’s going to be much lighter. In fact, we do have a stock S197 flywheel here, along with our scale, and that weighs in at roughly 22.5 – 23 lbs, compare that with our Exedy flywheel, which does weigh about 16 lbs so depending on your application, you’re going to be shaving off about 6-7 lbs of rotational mass from your drivetrain. That’s huge, getting rid of that much mass from your drivetrain when it’s rotational mass, means the engine is going to feel more responsive, it’s going to rev quicker, and as a result your car is sure to accelerate to red line a little faster. OF course if you did want to learn more about the benefits of a lightweight flywheel you can always give us a call at 855-422-7439, or shoot us an email at support@AmericanMuscle.com. In addition both the SFI certified 6 and 8 bolt flywheels are made from solid one piece chromoly steel forgings, making them extremely strong in addition to being lightweight. Since they are one piece, all the ring gear teeth around the outside here are actually part of the flywheel itself, as opposed to other aluminum aftermarket flywheels which do have the ring gear teeth pressed onto the flywheel, which can be a known weak spot for failure down the road. Another unique feature of the Exedy flywheel is that they incorporate a special design into the flywheel itself to enhance air flow to both the clutch disk and the flywheel surface area. This is huge because as you may or may not know the biggest enemy to any clutch is excessive heat. Excessive heat will cause your clutch to start slipping like crazy and eventually it may glaze over possibly causing permenent damage to both the clutch disk and the flywheel itself. Whenever installing a new aftermarket clutch we strongly recommend going with an aftermarket flywheel of the same brand. So obviously if you’re going with an Exedy clutch we recommend going with the Exedy flywheel here just to ensure fitment and operation. It also makes sense to install both at the same time since obviously the trans will need to be dropped to do both. If this is something you haven’t done before, we recommend getting this one done by your local shop, on the other hand if you do this kind of thing all the time and you have access to all the right tools, just leave yourself about 4 hours or a nice Sunday afternoon in the garage to get everything bolted up, and don’t forget to follow the recommended manufacturer break in procedure for your clutch, before you really start beating on the car. Exedy’s lightweight racing flywheel offers a solid one piece chromoly construction, that reduces the rotational mass of your drivetrain , all of which results into a freer revving, more responsive engine and of course it can be found right here at AmericanMuscle.com, and if you should have any questions on what flywheel you need for your application, whether it’s 6 or 8 bolt, just give us a call at 855-422-7439.

Slight chatter. Still hooks just annoying but it’s probably the throw out bearing. Easy installHelpful (0)

I was apprehensive about a lighter flywheel having driven race cars in the past. I thought it would it would make the car less drivable on on the street (i use my car for track days and street). After it was installed I noticed no drivability issues. The car was more fun to drive both on track and on street. Reves cane quicker and lap times went down (i have the data logs to prove it. Definitely a worthwhile upgrade.Helpful (0)

Still in break in but love it
about 400 miles on the clutch and flywheel for the break in process and I'm very happy with the results. car does rev a little faster. has a noticeably faster acceleration in 3-4 gear. overall I'm very pleased with the results so far. had a shop do the install and said they had everything they needed. I did have a nasty grinding noise on startup and they discovered the separator plate was an older version. got me the new version and now no grinding or rattle at 2000-2500rpm when cold!Helpful (0)

Shipping was garbage
Box came smashed up, but everything inside looks fine. You’d think for the price that you would get new flywheel bolts too but that’s just a petty complaint.Helpful (1)

Bad waist of time
I bought this flywheel for my 6 bolt crank and it does not fit. I sent it back to them and they gave me a new flywheel and still it doesn’t fit don’t waist your time or moneyHelpful (2)

Fit great and looked great. It revs a lot faster than before. I'm still in the break in period on the clutch so I haven't noticed any performance or acceleration differences but overall a good product to pair with the exedy mach 350 clutch kit. Make sure you get a pilot bearing puller tool before you start the project, it will save you time and a headache.Helpful (3)

Bought this back in July '18 to go w\ an Exedy Mach 500 Stage 3 Grooved Clutch kit to get installed in my '09 GT. Finally came time to get all installed after recently noticing clutch engaging very high in pedal travel (sign of worn clutch disc) and finding my clutch master cylinder had started leaking brake fluid out back beside push rod (OEM plastic unit). Took car to local Ford dealer (only place around that I trust w\ my car) Monday to get all installed. Got car back today and all is good. Clutch is now engaging very low in pedal travel and is grabbing very quick due to the grooved PP and it's increased clamping pressure but is smooth w\o any chattering so surface mating is excellent..... Weighed OEM flywheel @ 22.0 lbs....weighed Exedy LRF @ 15.2 lbs so shaved 6.8 lbs of flywheel mass off engine. Engine is showing no signs of low RPM rotational inertia loss on 1st gear takeoff from the flywheel weight difference so this is an excellent finding as drivability is fully retained but engine does rev up a little quicker which makes my car more touchy on accelerating smoothly (have a BBK 62mm TB installed which adds to it) off 1-2 and 2-3 gear changes so I may have to have the TB response rate readjusted in the tune to soften it's response a little more to compensate. Once I get the clutch fully broken in it should ease up on some of the grabbiness as well and become a little more controllable to feather on engagement. Would recommend this product to anyone who is looking to upgrade their clutch setup!Helpful (5)

Fitment was spot on. Didn't have any problems with it and a huge difference in weight. Also noticed that engine reved quicker.Helpful (4)

I loved how my car feels after this upgrade i recommend getting the exedy clurch tooHelpful (5)
How is this flywheel as a daily driver in traffic?
This flywheel is going to be lighter which would cause the engine to rev quicker and the clutch to grab harder. This would be okay for use on a daily driver if you were looking for a sportier clutch feel.
I was wondering if installing this lightweight flywheel with the Exedy Mach 400 stage 2 clutch would cause a stalling issue? I've heard that after hard accelerations or simply sometimes just putting your car into neutral with a lightweight flywheel, you're car may stall? Will this happen with this model on a 2002 Mustang GT?
Hello! It really depends on vehicle as it differs from one to another. Some people experience this problem and others do not so it is hard to say.
what if my eight digit is a H would this fly wheel be compatible
If your digit is "H", you will have a 4.6L motor. The 4.6L motor is in the 2005-2009 V8 Mustangs. This will fit with that motor.
Your info in the PLEASE NOTE section is incomplete, because I have a 2008 Mustang GT 4.6 V8 w/manual Trans and there is no X or W in my VIN. Mine has an H in the 8th place. So, do I have a 6 or 8 bolt crank?
That notation only applies to the 99-04 model years. All GT models in the 05-09 year range have an 6 bolt crank.
does it come with aftermarket dowel pins? mine did not, i do not know what size i need?
Yes dowel pins are supposed to come with an order of this clutch. If you order this clutch and do not receive dowel pins, or in general if you order anything and don't receive everything you were supposed to receive, please contact our customer service team right away so they can offer their assistance.
This flywheel has a disc diameter of 11 inches.
We do not carry a direct replacement from Exedy, however, we do offer these here from Ford Performance. https://www.americanmuscle.com/flywheel-step-dowel-pin.html
This will contain the flywheel and the 3 dowel pins.
This Exedy Lightweight Racing Flywheel runs a 6-Bolt pattern.
The Exedy Lightweight Racing Flywheel will use the same balance weight as the OEM flywheel, allowing the stock harmonic balancer to be used.
Yes, the dowel pins are necessary for the installation of the flywheels.
The Exedy Lightweight Racing Flywheel is about 9-10 lbs lighter than the stock flywheel.
If you are replacing your clutch with another Exedy clutch you can keep your existing Exedy Flywheel if resurfacing it will allow it to be reused. Otherwise, you will want to pair your replacement clutch with a manufacturer matching flywheel, as this flywheel is specifically for Exedy clutches.
The Exedy Lightweight Racing Flywheel is 11 inches in diameter.
Clutches and flywheels can be mix-matched, however, due to differences in manufacturing tolerances, some clutches and flywheels may not work at all, so we also recommend using the same brand for the clutch as the flywheel. The McLeod Street Pro Clutch, Item 62616, is best used with a McLeod flywheel for your Mustang. We would also recommend that the Exedy Lightweight Racing Flywheel - 6 Bolt, Item 62511, be used with an Exedy clutch only.
