The Sitrak Truck ABS Front Wheel Hub Assembly is a critical, integrated component that combines wheel mounting, bearing support, and ABS functionality for Sinotruk Sitrak heavy-duty trucks. As a core element within the comprehensive range of Sinotruk Sitrak parts, this assembly is engineered to ensure safe wheel rotation, reliable load-bearing, and precise data input for the vehicle’s Anti-lock Braking System. Its robust construction and integrated ABS tone ring provide essential performance for modern braking safety systems under demanding commercial transport conditions.
The Sitrak Truck ABS Front Wheel Hub Assembly is a complete, ready-to-install unit that serves as the central rotating hub for the front wheels, incorporating a built-in ABS tone ring (exciter ring). This assembly provides the mounting point for the wheel via wheel bolts, houses the wheel bearings, and features a precisely machined toothed ring that works in conjunction with the ABS wheel speed sensor. It is the crucial physical interface that allows the ABS computer to monitor each wheel’s rotational speed, enabling the system to prevent lock-up during braking and maintain vehicle stability.
At its core is the front wheel hub (Part No. WG4005415543), a high-strength, precision-machined component typically made from forged or cast steel. It is designed to withstand the immense axial and radial loads from the vehicle’s weight, cornering forces, and braking torque. The hub provides the inner and outer bearing seats for tapered roller bearings (like the 30311/30313 used in the system), which are critical for smooth, low-friction rotation. The integrity of this hub is paramount for safe wheel alignment, bearing life, and overall wheel-end performance.
The integrated ABS tone ring (Part No. WG4005415542) is a key differentiator for this assembly. This is a steel ring with precisely spaced teeth that rotates with the hub. As the teeth pass by the stationary ABS sensor, they generate a variable reluctance signal that the vehicle’s ABS control module interprets as wheel speed. The accuracy and concentricity of this tone ring are vital for providing a clean, consistent signal. Any damage or runout can cause erratic ABS operation, trigger warning lights, or disable the anti-lock system, compromising safety.
The assembly is completed with a set of high-tensile wheel bolts (Part No. WG4005415513), which are responsible for securely clamping the wheel to the hub flange. These bolts are manufactured to strict torque and fatigue specifications, as their failure could lead to catastrophic wheel separation. When installed as a complete unit, the Sitrak Truck ABS Front Wheel Hub Assembly ensures all these critical components—hub, tone ring, and mounting hardware—are perfectly matched and work in harmony, restoring the wheel end to like-new condition and ensuring the ABS system receives accurate data.

Our Sitrak Truck ABS Front Wheel Hub Assembly is a genuine OEM component, ensuring perfect compatibility and performance with your Sinotruk vehicle’s front axle and ABS system. The precise integration of the hub and the ABS tone ring is calibrated to factory specifications, guaranteeing accurate wheel speed signal generation. This is critical for the proper function of the ABS, traction control, and stability systems. Choosing our genuine assembly eliminates the risks of signal errors, ABS warning lights, or system deactivation that can occur with mismatched or poor-quality aftermarket components.
Safety and durability are engineered into every aspect. The wheel hub is forged from high-grade alloy steel and machined to exacting tolerances for perfect bearing fit and wheel alignment. The integrated ABS tone ring is made from durable steel and is securely attached to ensure concentricity and prevent signal dropout. The included wheel bolts are manufactured to high tensile standards for reliable clamping force. This robust construction withstands the extreme stresses of heavy loads, high temperatures, and harsh road conditions, providing long-lasting reliability and peace of mind for fleet safety.
We provide a complete, ready-to-install solution that simplifies maintenance and saves valuable workshop time. Our assembly comes with all the core components needed for a comprehensive wheel-end repair: the hub, tone ring, and wheel bolts. This ensures perfect compatibility between parts and eliminates the need to source them individually. Installing our complete assembly restores the entire wheel speed sensing and mounting interface in one step, ensuring optimal performance of both the mechanical and electronic systems while reducing the risk of installation errors.
Investing in our high-quality assembly delivers significant long-term value by protecting your broader vehicle systems. A true-running hub prevents uneven tire wear and bearing premature failure. An accurate ABS tone ring ensures the safety systems function correctly, preventing accidents and potential costly downtime from ABS-related faults. By maintaining the integrity of the wheel end, you also protect more expensive components like axles and brake systems. Backed by reliable support and availability, our Sitrak Truck ABS Front Wheel Hub Assembly is a smart investment in the safety, efficiency, and total cost of ownership of your commercial vehicle.
