The WG9719950156 Sitrak 6X4 Rear Fender Tie Rod is a critical component that connects the rear fender to the chassis frame, providing lateral stability and preventing vibration-induced fatigue. Made from high‑strength carbon steel with a corrosion‑resistant zinc‑phosphate coating, this tie rod withstands road salt, mud, and constant flexing. Its precise length and pre‑formed bends match the original SINOTRUK design, ensuring that the rear fender remains securely positioned over the tandem axles.
Each WG9719950156 tie rod features forged ends with integrated bushings that absorb chassis torsion. The rubber‑metal bushing at each end dampens vibrations and allows controlled movement, preventing metal‑to‑metal contact and extending the service life of both the fender and the chassis mounting points. OEM specifications require a minimum tensile strength of 600 MPa, ensuring the tie rod can endure the dynamic loads encountered during heavy braking and uneven road surfaces.
When a tie rod becomes damaged or corroded, the rear fender may sag, leading to tire rubbing, increased aerodynamic drag, and potential safety violations. Replacing worn components with genuine WG9719950156 restores the original alignment and appearance of the truck. Fleets operating in harsh environments should inspect tie rods regularly as part of their chassis maintenance program.
Exactly 785 mm center‑to‑center, with pre‑angled ends to match the Sitrak 6X4 chassis geometry. No cutting or modification required during installation.
Zinc‑phosphate + epoxy powder coating provides 720 hours salt spray protection. Bushings are made from UV‑stable rubber with steel inserts.
Integrated rubber‑metal bushings absorb road shock and chassis flex, preventing cracking of the fender mounting tabs and extending component life.
Uses original mounting points with M12 bolts (included). Meets all SINOTRUK quality standards for fit, form, and function.
The WG9719950156 Rear Fender Tie Rod is specifically designed for SINOTRUK Sitrak 6X4 tractor and rigid truck configurations. It fits models with rear tandem axles and plastic or steel fenders, including the C7H 6X4, T7H 6X4, and A7 6X4 series. It is also used on certain HOWO 6X4 chassis that share the same rear fender mounting architecture. Always verify the original tie rod length before ordering; this part replaces the factory component with part number WG9719950156.
The tie rod connects the rear fender to the chassis rail at an angle that accommodates suspension articulation. It allows the fender to move with the axle while maintaining clearance. For trucks equipped with air suspension, the WG9719950156 provides the necessary flexibility while keeping the fender aligned. In applications where the original tie rod has been damaged by corrosion or impact, replacing it with the genuine part restores the original appearance and prevents costly fender replacement.
For fleet standardization, stocking WG9719950156 tie rods ensures that any Sitrak 6X4 in the fleet can receive a quick fender repair. The part is interchangeable across model years (2014–present) as long as the fender design remains unchanged. Always use the included mounting hardware to avoid mismatched bolts that could cause premature wear.

* All specifications are based on SINOTRUK original engineering drawings. Inspect the tie rod for any shipping damage before installation.
Replacing the WG9719950156 rear fender tie rod is a straightforward process. Lift the rear of the truck and support the chassis securely. Remove the two M12 nuts securing the old tie rod to the fender bracket and chassis rail. Inspect the mounting tabs for damage or rust; clean them with a wire brush if needed. Position the new tie rod so that the rubber bushings seat properly. Install the new flange nuts and washers, then torque to 85 Nm. Ensure the fender is level and does not contact the tires.
Routine inspection every 50,000 km is recommended. Look for cracked rubber bushings, corrosion on the rod, or loose fasteners. If the bushings show excessive wear, replace the tie rod as a complete unit. Do not attempt to weld or repair a damaged tie rod; it must be replaced with a genuine WG9719950156 to maintain structural integrity. For trucks operating in corrosive environments (salt spreading, chemical plants), consider replacing tie rods every 300,000 km as preventive maintenance.
After installation, verify that the tie rod does not interfere with any brake lines or suspension components. Cycle the suspension through its full travel (if possible) to confirm adequate clearance. A properly installed WG9719950156 tie rod will allow the fender to move vertically while maintaining lateral position, preventing tire rub and extending fender life.
Aftermarket rear fender tie rods often use thinner steel or inferior bushings that fail within a year. They may also have incorrect lengths, causing the fender to sit too high or too low, leading to tire contact or aerodynamic drag. Genuine WG9719950156 tie rods are manufactured with precision‑bent tubing and forged ends that match the original stress analysis. The rubber‑metal bushings are formulated for heavy‑duty vibration damping and resist oil and ozone degradation.
The powder coating on OEM parts is applied after thorough surface preparation, ensuring adhesion and corrosion protection. Generic parts often have thin paint that chips easily, leading to rust within months. Replacing a tie rod that has failed due to corrosion costs not only the part but also labor and potential fender damage. Investing in genuine WG9719950156 provides peace of mind and lower total cost of ownership.
For fleets, using genuine parts also simplifies warranty claims and ensures that repairs meet manufacturer specifications. Many transport authorities require that safety‑related components (such as fender attachments) be OEM or equivalent. Keep a record of tie rod replacement dates and torque values in your maintenance system to demonstrate compliance.
The WG9719950156 Sitrak 6X4 Rear Fender Tie Rod is a simple yet vital component that keeps your truck looking professional and operating safely. Its durable construction, corrosion resistance, and precise fit make it the ideal choice for maintenance and repair. Choose genuine SINOTRUK Sitrak parts to ensure that every component meets the rigorous standards of heavy‑duty transport.
