B12-B13 is an OEM-standard clutch driven disc specially developed for domestic mini passenger cars and lightweight commercial vans. Produced strictly in accordance with original factory design drawings, dimensional tolerances and heat treatment standards, this core friction transmission component cooperates with B12-B13 matched pressure plate, engine flywheel and release bearing to realize stable torque transmission and rapid power separation. It is designed to adapt to frequent stop-and-go urban traffic and low-load short-distance transportation, serving as a cost-effective replacement solution for severely worn, burnt or damaged original clutch discs.

The core strength of B12-B13 lies in its precise 1:1 OEM fitment. All key parameters including overall outer diameter, spline tooth size, rivet layout, friction lining thickness and hub contour are completely consistent with official B12-B13 specifications. Repair technicians can complete direct bolt-on installation without cutting, drilling or secondary trimming. Zero assembly clearance thoroughly avoids common failures such as disc shaking, uneven friction and clutch slipping caused by poorly matched inferior spare parts, significantly accelerating vehicle maintenance efficiency and lowering long-term repair expenditure for individual car owners and small delivery fleets.

In terms of friction material, B12-B13 adopts eco-friendly non-asbestos organic composite lining customized for light-load mini vehicles. The material maintains a stable friction coefficient under continuous semi-clutch operations in congested city roads. It features excellent heat dissipation and thermal fading resistance, effectively preventing typical faults including lining scorching, power attenuation and weak vehicle startup. Compared with cheap low-quality friction discs on the market, this lining maintains steady friction performance for a much longer service life and reduces the frequency of repeated clutch replacement.

The central hub adopts multi-group lightweight torsional damping spring structure. Small-displacement gasoline engines produce obvious vibration during startup, idling and gear shifting; the built-in buffer springs efficiently absorb instantaneous torque shock. This structural design greatly reduces transmission jitter, abnormal gearbox rattling and stiff clutch pedal feedback, bringing softer and smoother power engagement and separation. Meanwhile, the damping mechanism relieves impact load on gearbox gears and drive shafts, protecting the entire transmission system from premature wear and damage.

The spline hub is processed through integral precision forging and one-time quenching heat treatment. It boasts high surface hardness and reliable torsion resistance. Even under long-term frequent shifting and bumpy suburban road conditions, spline tooth skipping, hub deformation and excessive abrasion rarely occur, ensuring consistent and stable power output all the time. Every finished B12-B13 clutch disc undergoes full factory inspections before packaging, including dynamic balance test, flatness detection and high-temperature endurance assessment, fully complying with global automotive spare parts quality control standards.

This clutch disc enjoys great popularity among overseas auto parts wholesalers, local repair garages and mini vehicle delivery fleets. With reliable durability, stable performance and competitive pricing, B12-B13 has become the ideal matching friction disc for B12-B12 pressure plate. We support separate supply of single clutch discs as well as complete three-piece clutch kits equipped with pressure plate and release bearing, to meet diversified one-stop bulk purchasing demands of international aftermarket buyers.
