Description
The EXEDY Flywheel – 1986–1989 Nissan D21 V6 is a focused driveline solution for 1986–1989 Nissan D21 V6, aimed at owners who want daily-driven and enthusiast street applications that need dependable engagement and OE-correct fitment without piecing together mismatched clutch components.
Manufacturer Background
EXEDY combines more than a century of Japanese clutch-manufacturing experience with a substantial OEM and motorsports presence. Originating in 1923 and known historically through Daikin Clutch, EXEDY designs replacement, sport, and racing driveline products with an emphasis on repeatable clamp load, heat management, durability, and controlled engagement.
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: FWNS27
- Configuration: Application-Specific 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 1986–1989 Nissan D21 V6, 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.
