Product Overview

ME521056 heavy-duty clutch disc is an OEM-standard transmission friction component exclusively developed for Mitsubishi Fuso medium and heavy trucks. Manufactured strictly per original factory drawing standards, it works with clutch pressure plate, flywheel and release bearing to transmit and cut off high diesel engine torque. It delivers stable startup, smooth gear shifting and reliable overload protection for long-haul freight trucks, construction vehicles and logistics fleets. This part shares universal interchangeability with ME521505 series clutch discs for the same engine platform.

Core Product Advantages

1:1 OEM Exact Interchange Fitment

All overall size, spline parameters, rivet layout and friction lining thickness fully match OEM ME521056 drawings. Direct bolt-on replacement without cutting, drilling or modification; zero assembly clearance, perfectly interchangeable with ME521505 for 6D14/6D16/6D17 engine trucks.

Heavy-Duty Ceramic Composite Friction Lining

Adopts asbestos-free high-load ceramic friction material with ultra-stable friction coefficient. Outstanding thermal resistance resists overheating, slipping and lining burning under continuous full-load climbing, frequent semi-clutch and long-distance highway transportation.

Multi-Stage Dual Torsional Damping Spring Hub

Equipped with thickened heavy-duty buffer spring groups (3S+3S / 4S+4S silent damping design). Effectively absorbs severe diesel engine torsional vibration, eliminates driveline jitter, gearbox abnormal rattle and harsh clutch pedal feedback, greatly extending the service life of gearbox and drive shaft.

Integral Forged & Quenched Spline Hub

Central spline hub adopts one-piece forging + high-temperature quenching tempering treatment. High surface hardness and superior torsion resistance, no tooth skipping, hub deformation or spline abrasion under full cargo load and harsh mountain road conditions.

Multi-Process Strict Factory Inspection

Each clutch disc undergoes dynamic balance test, flatness detection, high-temperature endurance test and spline matching inspection before shipment. Stable consistent quality for global aftermarket wholesale and repair shop overhaul projects.
