Exedy 1996-2016 Ford Mustang V8 4.6-5.0L Racing Lightweight Flywheel (8 Bolt)
The Exedy EF502A is a one-piece billet chromoly flywheel for V8 manual Mustangs with the 4.6L or 5.0L modular engine and an 8-bolt crankshaft flange. Owners buy it when the factory flywheel is cracked, heat-checked or worn past resurfacing, or when they want the engine to rev more freely on a GT, Mach 1, Cobra, Bullitt or Coyote car. It is also the part to have ready before a clutch upgrade, because a high-grip disc on a tired flywheel face chatters and slips no matter how good the clutch is.
The flywheel bolts to the rear of the crankshaft and does three jobs: it carries the ring gear the starter engages, it provides the friction face the clutch disc clamps against, and its mass smooths the engine's power pulses. The EF502A is machined from a single piece of chromoly steel, which is much harder and stronger than plain carbon steel, and Exedy states its racing flywheels carry SFI 1.1 certification, the standard most drag tracks check for. Published weights run about 16 lb; Steeda lists 16.1 lb.
Less rotating mass lets the engine gain and lose rpm faster, so rev-matched downshifts come quicker and the car pulls harder through the gears. Expect a trade: a lighter flywheel makes takeoffs from a stop less forgiving and can add some gear rattle at idle.
Most flywheel faults are found once the transmission is out, so measure and inspect the old part during the clutch job. Check the face for cracks, heat checking and runout, and look at the ring gear. On the road, separate a slipping clutch from a hydraulic or release issue first with our slipping diagnosis guide, and use shift flare vs. slip to tell a brief rev rise during a slow shift from a disc that is really slipping. If you are pricing the whole job, our manual transmission repair cost guide breaks down what to expect.
Our listing covers 1996-2016 Mustang V8 4.6-5.0L with the 8-bolt crank. Exedy's application list includes the 1996-2017 Mustang GT, the 1997 Cobra, 2003-04 Mach 1, 2008-09 Bullitt and the 2007-14 Shelby GT500. Modular V8s were built with both 6-bolt and 8-bolt crankshaft flanges depending on year and engine plant, and Exedy sells a separate 6-bolt flywheel, so count the bolts on your current flywheel before ordering. Ring gear tooth count and clutch diameter also differ between generations, so match your clutch kit to the flywheel or send us your year, VIN and clutch part number and we will confirm the combination.

Count the bolts holding your current flywheel to the crankshaft. Modular V8 Mustangs came with both patterns depending on year and engine plant. EF502A is the 8-bolt part; Exedy sells a separate 6-bolt flywheel.
Published weights are about 16 lb, and Steeda lists it at 16.1 lb. It is a one-piece billet chromoly steel flywheel.
Exedy states its chromoly lightweight racing flywheels carry SFI 1.1 certification.
It can, as long as the clutch diameter and bolt pattern match the flywheel. Send us your year, VIN and the clutch part number and we will confirm before it ships.
Yes. Replace the pilot bearing, release bearing and flywheel bolts, and inspect the rear main seal. Doing the clutch at the same time saves a second transmission removal.
The engine revs up and down faster, which helps acceleration and downshifts. Takeoffs need a little more throttle and you may hear more gear rattle at idle.
