The ECAS Height Sensor is a precision potentiometer that continuously monitors the vehicle’s ride height and sends real‑time signals to the ECAS control unit. It is mounted on the chassis and linked to the axle via a connecting rod, providing accurate feedback for automatic leveling and load compensation.
The Hexagon Flange Bolt M10 is a high‑strength fastener used to secure the height sensors, brackets, and lateral rods to the vehicle chassis. Its integrated flange eliminates the need for a separate washer, providing a larger bearing surface and improving resistance to loosening under vibration.
The Hexagon Flange Nut M10 is the matching nut for the flange bolt, providing a secure and vibration‑proof fastening solution. Its flanged design distributes clamping load evenly, ensuring that the ECAS components remain firmly attached under all operating conditions.
The ECAS Right Lateral Rod is a precision‑formed steel linkage that connects the right‑side height sensor to the suspension component. It transmits the vertical movement of the axle to the sensor, enabling accurate height measurement for the right side of the vehicle.
The ECAS Left Lateral Rod is the mirror‑image counterpart for the left side, providing balanced sensing capability. Both lateral rods are made from corrosion‑resistant steel and feature ball‑joint ends for smooth, friction‑free articulation.
The ECAS Connecting Rod is an adjustable linkage that transmits the suspension movement from the axle to the height valve or sensor. Its length can be fine‑tuned to achieve precise height calibration, ensuring optimal system performance.
The Hexagon Nut is a standard M10 nut used for general fastening applications within the ECAS Chassis Electronics system. It is manufactured from high‑grade steel with a zinc‑plated finish for corrosion resistance.
The ECAS Height Valve Bracket is a robust steel mounting plate that holds the height control valve in the correct position on the chassis. It is designed to accommodate the valve’s connections and provide a stable platform for accurate suspension control.
Every component in the ECAS Chassis Electronics kit is manufactured to Sinotruk’s original equipment specifications, ensuring perfect fit and seamless integration with the C7H suspension system. The sensors and linkages are calibrated for accurate height control.
The ECAS Chassis Electronics system delivers precise, repeatable height adjustments, improving load stability, trailer alignment, and driver comfort. The sensors provide real‑time feedback for automatic leveling.
We supply all necessary fasteners – flange bolts, flange nuts, hex nuts, and brackets – to ensure a comprehensive installation. No additional parts are needed, simplifying the replacement process.
All components are built with corrosion‑resistant materials and coatings, ensuring long‑term reliability in harsh environments. The sensors are sealed against moisture and vibration, maintaining accurate performance.
The ECAS Chassis Electronics system is a critical component for maintaining optimal ride height and suspension performance in the Sitrak C7H. It consists of height sensors, lateral and connecting rods, and a height valve bracket, all working together to provide automatic leveling.
The two height sensors (left and right) are mounted on the chassis and connected to the axle via lateral rods and connecting rods. As the suspension moves, the rods rotate the sensors, which send variable voltage signals to the ECAS control unit, allowing it to adjust air spring pressure accordingly.
The right and left lateral rods are precision‑formed steel links that transfer the axle’s vertical movement to the sensors. Their ball‑joint ends allow for smooth articulation, preventing binding and ensuring accurate sensor readings.
The ECAS Connecting Rods are adjustable in length, allowing the installer to fine‑tune the sensor’s zero position and overall ride height. This adjustability is essential for achieving the correct vehicle stance and load distribution.
The ECAS Height Valve Bracket is a sturdy mounting plate that secures the height control valve to the chassis. The bracket positions the valve so that its linkage can be connected to the suspension, ensuring accurate leveling response.
All fasteners in the kit – M10 flange bolts, M10 flange nuts, and hex nuts – are made from high‑strength steel with corrosion‑resistant plating. The flange design provides a wider clamping surface, reducing the risk of loosening under vibration.
Over time, height sensors can wear out or become damaged due to corrosion or impact. Replacing them with our genuine ECAS Chassis Electronics kit restores accurate suspension control, improving ride quality and reducing tyre wear.
Installation of the ECAS Chassis Electronics kit is straightforward with basic hand tools. The sensors are pre‑calibrated, but the connecting rods may need adjustment to match the vehicle’s specific ride height. A detailed instruction manual is included.
For fleet operators, maintaining a consistent ECAS Chassis Electronics system across all vehicles simplifies diagnostics and reduces spare parts inventory. Using genuine components ensures that all trucks exhibit the same handling and leveling characteristics.
The sensors are designed to operate in a wide temperature range from -40°C to +85°C, making them suitable for global operation. Their sealed housing protects against moisture and dust ingress, ensuring long‑term reliability.
We recommend checking the sensor and linkage condition periodically, especially after off‑road use or heavy impact. Loose fasteners or worn rod ends can cause erratic height control, which can be corrected with our genuine replacement parts.
The ECAS Chassis Electronics kit is compatible with all Sitrak C7H variants, including 4×2, 6×4, and 6×2 configurations. It is also suitable for use on other Sinotruk models that share the same ECAS architecture.
