Precision and safety in heavy-duty trucking are paramount, and every component plays a critical role. The Sitrak Spacer Assembly (ABS) is a vital, yet often overlooked, sub-assembly that ensures the proper positioning and secure mounting of the ABS (Anti-lock Braking System) sensor on your Sinotruk vehicle. This specific kit, available as a genuine Sinotruk Sitrak parts, is engineered to maintain the exact air gap between the ABS tone ring and the sensor, which is essential for accurate wheel speed signal generation. A correctly installed Spacer Assembly is fundamental for the reliable operation of the entire ABS, a system crucial for preventing wheel lock-up and maintaining vehicle control during emergency braking maneuvers.
The Sitrak Spacer Assembly (ABS) is a precision mounting kit designed to correctly position and secure the ABS wheel speed sensor to the axle housing or brake backing plate. It consists of a rigid sensor bracket, high-strength socket head cap screws, and spring washers. Its primary function is to establish and maintain a fixed, manufacturer-specified distance (air gap) between the tip of the sensor and the rotating ABS tone ring on the wheel hub or axle shaft.
This precise gap is non-negotiable for the electromagnetic sensor to generate a clear and consistent digital signal. If the sensor is too close, it may risk physical contact and damage from vibration or debris; if it’s too far, the signal becomes weak or erratic, potentially causing the ABS control module to misinterpret wheel speed or even disable the system entirely, triggering a fault code.
The assembly is engineered for robustness in a harsh environment. The bracket is typically made from stamped or cast steel to resist bending and corrosion. The included screws and washers are of automotive grade to withstand constant vibration and thermal cycles without loosening, ensuring the sensor’s position remains stable over thousands of kilometers.
While it may seem like a simple set of brackets and fasteners, the Sitrak Spacer Assembly (ABS) is a critical safety component. It guarantees that the sophisticated electronic safety systems in your truck receive accurate data, enabling them to function as designed. Replacing worn or damaged spacers and fasteners with this genuine kit is a crucial step during ABS sensor replacement or wheel-end service.

Note: This assembly provides all necessary hardware for securely mounting a single ABS sensor. Always replace all components together to ensure proper torque and clamp load.
Our genuine spacer assembly is manufactured to exact OEM tolerances, guaranteeing the correct sensor alignment and air gap. This precision is vital for generating a clean, uninterrupted wheel speed signal, which is the foundation for effective ABS, traction control, and stability program operation. Accurate signals prevent false activations or system failures.
The sensor bracket is constructed from robust materials to resist corrosion and deformation from road impacts and vibration. Paired with high-grade, properly hardened socket head screws and spring washers, this assembly provides a vibration-resistant, secure mount that keeps the sensor firmly in place throughout the vehicle’s service life.
As an authentic Sinotruk Sitrak part, this assembly is designed specifically for your vehicle model. It ensures a perfect fit with the existing mounting points on the axle or brake assembly, eliminating guesswork, modification, or the risk of interference with other components. This seamless compatibility saves time during installation and guarantees system integrity.
A properly functioning ABS is a legal and safety requirement in most regions. Using our genuine Sitrak Spacer Assembly (ABS) helps maintain this critical system in optimal working order. It’s a small investment that contributes directly to the safety of the driver, the cargo, and other road users by ensuring the braking system can perform optimally in emergencies.
The Sitrak Spacer Assembly (ABS) may be a small component, but its role in vehicle safety is immense. Ensure your truck’s advanced braking systems have the reliable foundation they need with this genuine, precision-engineered mounting kit.
