Sinotruk HOWO Spare Parts — Order by OEM Part Number

Why Order Spare Parts From the Same Supplier as Your Truck

If you already buy Sinotruk HOWO trucks from us, sourcing parts from the same supply chain solves a real problem. A truck down for a differential, a shock absorber, or a locking valve is a truck earning nothing — and in most of our markets, the part that fails first is not always the part the local supplier has in stock.

• One point of contact. You already know how we quote, ship, and document a truck order. Parts follow the same process, so there's no new supplier relationship to vet.
• Matched to the platform. We're sourcing against the same HOWO A7, N7/NX, and T7 platforms we export, so the part numbers we quote are the ones that actually fit the trucks in our stock — not a generic cross-reference.
• No idle-truck guessing. Order wear items — cab door hardware, mirrors, brake chambers, engine mounts — ahead of time when you place your truck order, and you start operations with spares already on hand instead of waiting on a first breakdown.

This works best for buyers who already have a truck order with us, or who are running a fleet of HOWO trucks bought from any source and want a second parts channel.

How to Order — Confirm Your Part Number First

Every Sinotruk part carries an OEM number — typically an AZ or WG prefix followed by a numeric code, stamped on the part itself or printed in the chassis parts catalog for your specific model. Before you send a request, check the number against one of these sources:

1. The part's own casting or label, if you're replacing something already removed from the truck.
2. The vehicle nameplate and VIN, which tells us the exact HOWO platform (A7, N7/NX, T7) and axle or engine series your truck was built on.
3. Your existing parts catalog or a prior supplier invoice, if you're reordering something you've bought before.

If you only have a description — ”the shock absorber under the cab” or ”the left door lock” — and not a number, send us photos of the worn part and your VIN instead. We'll cross-check it against the OEM catalog before quoting, because ordering the wrong part number wastes freight cost on both ends and delays the fix you actually need.

OEM Part Numbers We Get Asked About Most

These are the Sinotruk HOWO OEM numbers our buyers request most often. If your number isn't listed here, send it anyway — this is a working list, not the limit of what we can source.

Beyond these three high-demand numbers, buyers also regularly ask about cab, brake, and chassis parts across the HOWO A7 and T7 range:

Genuine OEM vs Aftermarket — What You're Actually Buying

Both genuine Sinotruk OEM parts and aftermarket copies fit the same bolt holes, so the difference doesn't show up until the part is under load. Here's the honest version, not the sales version:

• Genuine OEM costs more upfront. For a wear item like a brake chamber or shock absorber, the price gap over a copy is real, and for a low-stress trim part — a door panel, a mirror housing — the gap may not be worth paying every time.
• Aftermarket quality is uneven, not uniformly bad. Some aftermarket suppliers in China produce parts to tight tolerances; others don't. Without a name you already trust, you're taking a risk you can't see until the part fails.
• Safety and drivetrain parts are where we recommend genuine. Differentials, brake components, and steering-related parts carry a real cost if they fail on the road — that's where the OEM premium is worth paying.
• We tell you which is which. When you send a part number, we confirm whether we're quoting genuine Sinotruk OEM stock or a tested aftermarket equivalent — we don't leave you to assume.

Shipping: With Your Truck Order or On Its Own

Most parts orders we handle ride inside the same container as a truck purchase — it's the cheapest way to move them and the reason this service works well for existing customers. If you're placing a truck order, tell us your parts list at the same time and we load both together.

Standalone parts orders are possible too, but freight economics work differently for a handful of small items than for a full container. Small, light parts — switches, locks, sensors — can move by air or as part of a consolidated parcel; larger or heavier items like a differential housing or engine mount usually wait for the next container run unless the order is urgent enough to justify air freight cost. We'll tell you which option makes sense for your specific order rather than quote a one-size freight rate.

Documentation for parts orders follows the same standard as our truck shipments: commercial invoice, packing list, and — where the destination country requires it — a certificate of origin.
