Dual Mass Flywheel Alfa Romeo Manufacturer China
Procurement teams sourcing a dual mass flywheel for Alfa Romeo applications need more than a catalogue match. They need dimensional control, repeatable damping behaviour, traceable materials, and an export supply chain that can support samples, pilot lots, and scheduled replenishment. Driventus supplies dual mass flywheel programmes for aftermarket distributors, wholesalers, repair chains, and OEM or Tier-1 sourcing teams that need consistent fitment rather than loose replacement claims. The critical checks are not limited to outer diameter. Buyers should confirm ring gear tooth count, bolt circle, stack height, starter engagement depth, imbalance limits, and the torque curve of the internal spring and friction pack. Our manufacturing and inspection processes operate under IATF 16949:2016 and ISO 9001:2015, with documentation support available for REACH (EC) No 1907/2006. Driventus is an independent aftermarket manufacturer; brand names are referenced for fitment only. If you need a China source with controlled quality and clear release criteria, the sections below show what to verify.
What buyers should verify before sourcing
For an Alfa Romeo programme, the buying decision should start with fitment data, not supplier claims. Ask for the engine code, gearbox code, clutch kit pairing, OE reference from the service catalogue, and the exact vehicle application range.
A useful release checklist is:
- Outer diameter, thickness, and total stack height
- Bolt circle, dowel pattern, and starter ring geometry
- Tooth count and engagement depth
- Axial and radial runout limits
- Static and dynamic balance records
- Friction face finish and surface hardness
- Packaging, rust protection, and lot traceability
If the part will be sold as an aftermarket replacement, confirm that the supplier can hold the same geometry across repeat batches. For a broader product view, see our catalog and the related engine components range.
Dimensional and functional controls
A dual mass flywheel is a controlled torsional device, so the inspection plan has to cover both geometry and motion. Buyers should request a first article report that includes concentricity, face runout, mass balance, free angular travel, and torque decay behaviour under cyclic loading.
| Control point | What is measured | Why it matters |
|---|---|---|
| Concentricity | Bore and face alignment | Reduces vibration and uneven clutch engagement |
| Axial runout | Face wobble under rotation | Limits pedal pulsation and noise |
| Balance | Mass distribution across the assembly | Lowers gearbox stress at idle and load changes |
| Spring response | Internal damping movement | Controls torsional shock during launch and shift |
| Tooth geometry | Ring gear accuracy | Supports reliable starter engagement |
