WG9761349001 Brake Drum for HOWO Heavy-Duty Vehicles
Products Description
As a critical safety component for HOWO heavy-duty trucks, the WG9761349001 brake drum serves as the core matching part of the drum brake system. By generating frictional braking force in conjunction with brake shoes, it ensures reliable vehicle deceleration and stable parking control. This part directly affects braking stability, heat dissipation efficiency, and overall driving safety. In particular, it can reduce the risk of brake fade by over 20% during continuous downhill driving or heavy-load braking. It is ideally suited for harsh operating conditions such as mining transportation, engineering construction, long-haul heavy cargo delivery, and mountain road operations.

Quality & Performance Assurance
Crafted from HT250 gray cast iron with a uniform metallographic composition, the WG9761349001 brake drum delivers superior structural rigidity and wear endurance. Its manufacturing workflow integrates precision die-casting, high-temperature stress relief annealing (to neutralize internal mechanical tensions), CNC precision machining (achieving ±0.1mm dimensional tolerance), and a specialized surface anti-corrosion coating process. The production facility is outfitted with automated molding systems and CNC machining clusters, boasting an annual output of 80,000 units to fulfill large-volume procurement requirements.
Three distinct quality tiers are offered to meet diverse application needs:
Genuine Original Equipment: Fully aligned with Sinotruk's factory technical benchmarks, identical to the original components fitted on new vehicles
OEM Equivalent Grade: Produced in strict accordance with original equipment design parameters, delivering premium performance at a cost-effective price point
Premium Replacement Grade: High-reliability aftermarket alternatives that meet all essential safety and operational criteria
Procurement & Service Support
1.Procurement Terms
We maintain long-term spot supply with a regular inventory of no less than 300 units. The minimum order quantity (MOQ) is set at 1 unit, allowing for sample procurement. Wholesale pricing is available for orders of 50 units or more. Regular orders are shipped within 48 hours upon receipt of payment, while bulk orders (≥200 units) have a lead time of 7–10 working days.
2.Packaging & Labeling
Packaging options include neutral cartons, custom brand packaging, and export-oriented wooden cases (featuring anti-collision and anti-deformation properties). Each product is protected with anti-rust paper and shock-absorbing foam, and affixed with a barcode label containing key information such as serial number, OE number, production date, and quality grade classification.
3.After-sales Guarantee
Genuine parts come with a 1-year or 100,000km warranty; OEM Grade parts offer an 8-month or 80,000km warranty; Premium Aftermarket Grade parts are covered by a 6-month or 50,000km warranty. Free replacement is provided for non-human-induced damages including cracking and abnormal wear. We also offer one-on-one compatibility confirmation services, electronic installation guidelines, and remote technical consultation for installation and debugging processes.
4.Customization Capabilities
We provide comprehensive OEM/ODM services, accepting custom processing based on customer-provided drawings or physical samples. Small-batch sampling can be initiated with a minimum of 10 units, with a sampling lead time of 15–20 working days. Customizable aspects include material grade upgrades (e.g., HT280 cast iron), surface coating processes, and adjustments to mounting hole dimensions.
FAQ
1.Practical Application Scenarios
The WG9761349001 brake drum serves as a mainstream supporting component for HOWO series heavy-duty vehicles across global markets, including Southeast Asia (Vietnam, Thailand), the Middle East (Iran, Saudi Arabia), Central Asia (Kazakhstan, Uzbekistan), Russia, and Africa (Nigeria, South Africa). It is extensively deployed in mining dump trucks, engineering concrete mixers, long-distance bulk cargo tractors, and container transport vehicles. Domestically, it has been installed in over 25 mining areas and logistics fleets, with cumulative installations exceeding 40,000 units, and annual overseas shipments surpassing 10,000 units.
2.FAQ
1.Is VIN-based matching supported?
Yes. Our technical team will verify and confirm the compatibility of the brake drum with your vehicle within 2 hours after you provide the VIN code.
2.What are the distinctions between the three quality grades?
Genuine parts adhere strictly to Sinotruk's original factory standards, making them ideal for high-end vehicle maintenance and original equipment matching. OEM Grade parts follow the same technical parameters as original parts, delivering excellent cost performance. Premium Aftermarket Grade parts meet daily operational needs at a more budget-friendly price point. All three grades ensure core braking safety performance.
3.Which payment methods are accepted?
We support T/T, L/C, and Western Union payments. Negotiations on installment payment terms are available for bulk order transactions.
4.Is sample testing available?
Yes. Single-unit samples can be provided for performance testing.
