Rear Hub Assembly OE 3104010-H0300 for Dongfeng GX&KX | Genuine Truck Part

This rear hub assembly OE 3104010-H0300 is manufactured strictly to Dongfeng GX&KX original design specifications, forged from high-grade ductile iron (QT450-10) that delivers exceptional structural rigidity and impact resistance—critical for heavy-duty axle load transmission. The product features a pre-installed high-precision tapered roller bearing system with integrated sealing, eliminating the need for separate bearing and seal installation. The robust stud design with high-strength wheel bolts ensures secure wheel mounting under extreme loads. It adopts a 1:1 original dimensional design, with precise axle bore and flange tolerances that perfectly match the truck’s rear axle and brake system, ensuring a tight, stable fit and uniform load distribution. This complete solution combines high load capacity and convenience, making it the ideal OEM replacement for Dongfeng GX&KX heavy-duty trucks.

Fully compatible with all applicable Dongfeng GX&KX truck models, this rear hub assembly can be quickly verified via OE 3104010-H0300 to ensure accurate matching. It solves multiple common failures caused by low-quality aftermarket hubs: inferior cast iron leading to cracking and fatigue, poor machining causing uneven load distribution, mismatched bearing sizes leading to premature wear, and insufficient sealing causing oil leakage and bearing contamination. A faulty rear hub will produce abnormal noise, cause wheel wobble and even rear axle breakdowns—posing a serious threat to driving safety and fleet operation. By using this genuine pre-assembled hub, users can eliminate hub wear, bearing failure and axle misalignment problems, ensuring reliable rear axle performance.

As a key component for heavy-duty truck axle systems, this rear hub assembly meets Q/DFL 6020-2021 Dongfeng automotive parts quality standards and has passed authoritative third-party tests for load capacity, wear resistance and fatigue life. Test data shows the hub withstands a dynamic load rating of ≥180kN, maintains stable performance after 10,000 hours of continuous operation under heavy load, and remains functional after 500 hours of salt spray testing. Each hub undergoes 100% dimensional inspection, bearing fit verification and fatigue testing before leaving the factory, ensuring complete consistency with original factory parts in performance, durability and fit. It performs reliably in all operating conditions, with strong resistance to wear, fatigue and corrosion. Backed by complete factory traceability and quality certification, it provides users with long-term, trustworthy rear axle performance.
