Description
Built specifically around the fitment requirements of Flywheel Sport, the EXEDY Lightweight Flywheel – Flywheel Sport gives owners a direct way to choose EXEDY hardware matched to daily-driven and enthusiast street applications that need dependable engagement and OE-correct fitment.
About EXEDY
Since 1923, EXEDY has developed clutch and powertrain components for OEM and performance use around the world. The company's Daikin Clutch heritage and motorsports engineering experience underpin a catalog that ranges from OE replacement hydraulics and clutch kits to SFI-certified sport clutches, chromoly flywheels, and Hyper multi-plate assemblies.
Driveline Role
EXEDY flywheels are engineered as matched driveline components rather than cosmetic weight reductions. Its lightweight performance flywheels use one-piece billet or forged chromoly steel construction to reduce rotational inertia while retaining high thermal capacity and integrated ring-gear strength.
A lighter flywheel can improve engine response and rev matching, but it can also reduce stored rotational energy and make low-speed takeoff more sensitive. It is best suited to drivers who value throttle response, faster transient behavior, and performance use over maximum factory-like smoothness.
Configuration
- EXEDY Part Number: ZF506
- Configuration: Lightweight Flywheel
- Construction / Character: EXEDY application-specific flywheel
- Torque Rating: Not rated independently as a clutch torque-capacity figure
- Best Suited For: Clutch service or performance builds requiring the listed EXEDY flywheel fitment
Choosing the Right Configuration
For Flywheel Sport, this configuration makes the most sense when its intended duty matches the vehicle's actual power and use. Avoid overspecifying clutch aggressiveness: the best setup is the one that maintains the needed torque reserve while preserving usable modulation and protecting the rest of the driveline.
