Products Description
The AZ9719430010 / DZ9100430011 Steering Drag Link Assembly is a premium OEM replacement component engineered for the steering systems of Sinotruk HOWO, HOWO A7, Shacman Delong, and Steyr heavy-duty trucks. As the critical link between the steering gearbox pitman arm and the steering knuckle, the drag link transmits the driver's steering input to the front wheels, directly determining steering response, vehicle stability, and driving safety.
Manufactured to exact OEM specifications, this drag link assembly features a solid forged 42CrMo alloy structural steel rod body that delivers exceptional tensile and yield strength. The ball joint pins are crafted from 20CrMnTi alloy steel, carburized and quenched to achieve a surface hardness of HRC60-65 while maintaining core toughness, ensuring superior wear resistance and preventing fracture under heavy-duty conditions.
The assembly includes an integrated automatic clearance compensation mechanism that uses high-tension springs to eliminate wear-induced gaps over time, ensuring axial play ≤0.3mm for responsive, zero-play steering. The rod features threaded ends for length adjustment, and the entire assembly is protected by a multi-layer anti-corrosion coating that withstands ≥1500 hours of salt spray testing.
This drag link is a direct replacement for the original factory unit, making it the ideal choice for fleet maintenance, repair shops, and heavy-truck parts distributors serving mining, construction, and long-haul freight operations.

Installation & Maintenance Notes
- Safety First: Ensure the vehicle is securely parked, wheels chocked, and the parking brake is engaged before beginning any work.
- Inspection: Before installation, inspect the steering knuckle, pitman arm, and all related components for wear or damage. Replace any worn components.
- Clean Components: Clean the mounting surfaces and thread areas. Remove all dust, rust, and debris.
- Adjust Length: Thread the ball joints to match the length of the original drag link. Count the turns on the old unit as a reference.
- Install the Assembly: Position the drag link and insert the ball joint pins into the pitman arm and steering knuckle. Hand-tighten the nuts first.
- Torque Specifications: Torque the ball joint nuts to the manufacturer's recommended specification (typically 450–500 N·m). Install new split pins.
- Alignment Check: After installation, perform a front-wheel alignment to ensure correct toe-in and steering wheel centering.
- Break-In: Drive the vehicle at moderate speeds and check for unusual steering play, vibration, or noise. Re-torque all fasteners after the first 100 km.
- Maintenance: Periodically inspect the drag link for bent rod, worn ball joints, or damaged dust covers. Replace the assembly if excessive play, steering wander, or uneven tire wear is observed.
⚠️ Warning: Do not attempt to heat, bend, or weld the drag link rod. These actions will compromise the structural integrity of the component and may lead to steering failure.
