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.\u003c\/p\u003e\u003ch3\u003eDriveline Role\u003c\/h3\u003e\u003cp\u003eEXEDY 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.\u003c\/p\u003e\u003cp\u003eA 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.\u003c\/p\u003e\u003ch3\u003eConfiguration\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEXEDY Part Number:\u003c\/strong\u003e FWNS27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Application-Specific Flywheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction \/ Character:\u003c\/strong\u003e EXEDY application-specific flywheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque Rating:\u003c\/strong\u003e Not rated independently as a clutch torque-capacity figure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBest Suited For:\u003c\/strong\u003e Clutch service or performance builds requiring the listed EXEDY flywheel fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eChoosing the Right Configuration\u003c\/h3\u003e\u003cp\u003eFor 1986–1989 Nissan D21 V6, this configuration makes the most sense when its intended duty matches the vehicle's actual power and use.
