Description
Maximize torque transfer efficiency and eliminate clutch slip across your commercial fleet with the genuine ZF Heavy Duty Commercial Vehicle Truck Clutch Disc. Engineered specifically for heavy-duty commercial truck gearboxes, manual transmissions, and transit bus powertrains, this OE-grade clutch disc transmits massive engine torque smoothly from the flywheel to the transmission input shaft under severe payloads. Glazed friction facings, sheared torsion springs, burned organic linings, or spline wear cause severe clutch slippage, harsh pedal vibration, delayed acceleration, and complete loss of propulsion. This original ZF clutch disc solves those driveline failures directly. It features premium heavy-duty organic or ceramic friction materials, high-strength torsion damper springs, precision-splined hubs, and burst-resistant glass fiber reinforcement to deliver uniform clamping pressure, ultra-smooth engagement, and uncompromised transport reliability in demanding fleet operations.
Technical Parameters
| Category | Specifications & Technical Details |
| High-Wear-Resistant Non-Asbestos Organic/Ceramic Facings | We manufacture the friction surfaces from non-asbestos high-strength copper-based organic fabric or heavy-duty sintered ceramic material. They deliver extremely high thermal fade resistance and friction coefficient. As a result, they handle frequent heavy truck launches and fully loaded hill climbs perfectly. |
| Multi-Stage Torsion Damper Spring Architecture | We integrate multiple sets of high-rigidity helical damper springs into the center disc. They effectively absorb and filter torsional pulses and shift shock from the engine output shaft. Moreover, they protect gearbox gears from resonance damage. |
| High-Strength Precision-Splined Hub | We forge the splined bore from high-alloy steel and apply high-frequency induction hardening. The tooth surface achieves extremely high hardness and wear resistance, meshing tightly with the gearbox input shaft spline. Consequently, it prevents spline stripping under long-term high torque. |
| Burst-Resistant Fiberglass Reinforcement | We embed multiple layers of high-strength fiberglass mesh inside the friction disc. It prevents the disc body from bursting or disintegrating even under ultra-high-speed centrifugal force and high-temperature baking. Notably, this safeguards driving safety. |
| Optimized Clamping Pressure & Clean Release | We follow ZF OEM design tolerances strictly. This ensures rapid, complete release the instant the clutch pedal is pressed. As a result, it completely eliminates gear grinding and half-engagement drag. |
Applicable Car Brands & Models
Common warning symptoms include:
Clutch Slippage Under Acceleration: Engine RPM increases rapidly when pressing the accelerator, but vehicle speed does not increase proportionally under heavy loads.
Burning Odor Near Cab: A distinct burning smell of hot friction material after climbing hills or towing heavy cargo.
Chattering or Shuddering During Launch: Violent shaking or jerking felt through the chassis when releasing the clutch pedal from a stop.
Difficulty Shifting Gears: Gears crunching or failing to engage smoothly due to the clutch disc failing to release completely.
Premature failure is typically caused by aggressive driving habits (such as “clutch riding” or towing loads exceeding rated GCW limits), oil contamination leaking from worn engine rear main seals or transmission input shaft seals, and weak pressure plate clamping force.
Yes. Fleet mechanics strongly recommend replacing the clutch disc, pressure plate, release bearing, and pilot bearing as a complete kit. Reusing an old pressure plate with weakened diaphragm springs or a worn release bearing will cause premature slip, vibration, and repeat component failure.
Our 1-year warranty covers all friction facing delamination, torsion spring fracture, hub spline stripping under specified torque, burst structural failure, and non-artificial manufacturing defects under normal operating conditions. If a clutch disc fails within 12 months, we provide prompt replacement or warranty processing upon inspection.
