As a core component of the automotive steering system, the steering rack converts the rotational motion of the steering wheel into linear movement to control vehicle direction accurately. Our steering racks are engineered to deliver durable performance, smooth operation, and enhanced safety for a wide range of vehicles.
Manufactured under strict quality standards in ISO-certified facilities, our products undergo rigorous testing for wear, impact, and fatigue resistance. With advanced materials and precision engineering, our steering racks ensure seamless compatibility and long service life, reducing vibration and noise while improving handling responsiveness.
The global steering system market continues to grow, driven by rising demand for electric power steering (EPS) and hydraulic systems. Our products support this trend, offering reliable replacements for both conventional and modern steering systems.
Ideal for aftermarket sales and commercial applications, our steering racks come with comprehensive warranty support and are trusted by professionals worldwide.
Our steering racks are precision-engineered to deliver exceptional responsiveness and control. Utilizing advanced rack-and-pinion technology, they ensure minimal friction and seamless power transfer, reducing steering effort by up to 30% compared to conventional systems. The integrated design optimizes force distribution, providing consistent performance across diverse driving conditions. With rigorous validation under ISO-certified processes, each unit guarantees smooth operation and enhanced driving safety.
Built for longevity, our steering racks feature robust materials and hardened steel components resistant to wear, corrosion, and extreme temperatures. Through finite element analysis (FEA) and fatigue testing, we achieve a 29.5% weight reduction without compromising structural integrity. This innovation extends product lifespan by 20% versus industry averages, making it ideal for commercial vehicles and harsh environments.
Every steering rack meets OEM specifications and international safety standards (e.g., EN 14363, EN 12299). With ISO 26262-certified development processes and 90 million+ global EPS deployments by our partners, we deliver proven reliability. Our products undergo NVH optimization and real-world simulation tests to minimize noise and vibration, ensuring premium driver comfort.
Leveraging modular platform designs (e.g., Double Pinion/Rack), we offer scalable solutions for diverse vehicle types, from compact cars to heavy-duty trucks. Our production lines achieve 95% component reuse rates, reducing development time and costs for clients.

Here are specific application scenarios of steering rack:
Our steering racks are engineered for the stop-and-go nature of city driving, providing smooth, responsive handling and reduced steering effort. This ensures a comfortable and low-fatigue driving experience during daily commutes, tight parking, and navigating congested traffic. The precision engineering minimizes vibration and noise, enhancing overall cabin comfort for the vast majority of passenger vehicles on the road today.
Durability is critical for taxis, delivery vans, and ride-sharing vehicles that accumulate high mileage rapidly. Our heavy-duty steering racks are built with robust materials and undergo rigorous fatigue testing (exceeding 500,000 cycles) to withstand constant use. This reduces downtime and maintenance costs, offering fleet operators a reliable, cost-effective replacement part that ensures driver safety and vehicle longevity.
Designed to perform reliably in challenging environments, from rough rural roads to regions that use road salt in winter. Our units feature superior corrosion resistance (tested to 720+ hours in salt spray) and robust sealing (IP67 rating) to protect against moisture, dirt, and debris. This ensures consistent performance and extended service life even under extreme conditions, preventing premature failure.
As a trusted OEM-quality replacement, our steering racks are the preferred choice for professional repair shops and mechanics worldwide. They offer a perfect fit and seamless integration, reducing installation time and ensuring customer satisfaction. Backed by global certifications (IATF 16949), they provide a reliable solution for addressing common steering issues like leaks, play, or stiffness, restoring vehicle safety and performance.
Our Electric Power Steering (EPS) racks are designed for the latest vehicle technologies. They support energy-efficient operation (reducing load on the engine) and are compatible with Advanced Driver Assistance Systems (ADAS) like lane-keeping assist. This makes them a future-proof solution for modern vehicles, ensuring owners maintain all original electronic functions and safety features after a replacement.
For optimal performance and safety, always refer to the vehicle manufacturer’s specifications during installation. Use calibrated torque wrenches to tighten mounting bolts to 70-90 Nm (industry standard) and ensure proper alignment of hydraulic/EPS connections. Pre-fill the system with ISO 46-grade hydraulic fluid or verify electronic calibration for EPS models. Test steering responsiveness post-installation and check for leaks/noise. Our products include QR-guided installation videos and comply with SAE J2562 safety protocols. For complex integrations, consult certified technicians.
