The automotive steering system is a specialized mechanism used to change or maintain the vehicle's direction. Its fundamental function is to control the vehicle's direction according to the driver's wishes, playing a crucial role in the vehicle's handling safety, driving comfort, and fuel economy.
EEP boasts a comprehensive steering system parts supply chain and service system, covering key components such as steering ball joints(tie rod end, rack end), steering rods, power steering gears, power steering pumps, steering universal joints, and steering boots. We are committed to providing steering system solutions with OEM-quality standards for a wide range of passenger cars and light commercial vehicles.
All EEP steering components comply with mainstream industry standards and safety regulations. Our products undergo extensive verification in material selection, structural design, fatigue durability, and environmental compatibility, ensuring reliability and longevity in complex operating conditions, making driving easier, more precise, and more energy-efficient.
Precision Steering System Parts Manufacturing & Engineering Solutions
EEP Auto Parts delivers precision-engineered steering system parts designed for responsive handling, accurate directional control, and long-term reliability across Japanese and Korean vehicle platforms. Our comprehensive product range includes rack and pinion assemblies, tie rod assemblies, steering gears, power steering pumps, steering knuckles, and complete steering linkage components - all manufactured using advanced CNC machining technology and rigorous quality verification protocols.
As a certified rack and pinion manufacturer holding ISO 9001:2015 and IATF 16949 certifications, we maintain precision manufacturing standards throughout our dedicated steering components production facility. Every steering gear and tie rod assembly undergoes multi-axis CNC machining with positional accuracy of ±0.01mm, followed by surface grinding to achieve Ra 0.4 µm finish on critical bearing surfaces. Our quality assurance process includes hydraulic pressure testing (2,000-3,000 PSI operational verification), rotational torque measurement, and comprehensive dimensional inspection using CMM technology.
Advanced Manufacturing & Quality Standards
Rack and pinion assembly production employs precision gear hobbing machinery achieving AGMA Class 8 gear quality with pitch accuracy within 0.008mm. Housing components are manufactured from high-strength aluminum alloy (A380.0) through gravity die-casting, maintaining wall thickness uniformity and pressure integrity for hydraulic steering applications. Internal sealing systems utilize multi-lip PTFE seals and polyurethane O-rings rated for -40°C to +150°C temperature range, ensuring leak-free operation over 150,000 km service life.
Tie rod assembly manufacturing integrates precision thread-rolling processes creating M14×1.5 and M16×1.5 metric threads with 6g tolerance class. Ball stud components undergo induction hardening achieving HRC 55-60 surface hardness across articulating surfaces, while integrated dust boots manufactured from chloroprene rubber (CR) provide superior weather resistance compared to standard EPDM materials. Each inner tie rod and outer tie rod assembly receives individual torque testing validating breakaway torque within manufacturer specifications.
Power steering pump production includes rotor vane machining maintaining 0.02mm clearance tolerances, pressure relief valve calibration (1,200-1,400 PSI settings), and flow rate verification (8-12 liters/minute at 1,500 RPM). Remanufactured steering components undergo complete disassembly, ultrasonic cleaning, replacement of wear items, and performance testing matching new component specifications.
Comprehensive Coverage & Distribution Solutions
Our OEM steering components catalog encompasses 6,200+ SKUs covering Toyota (Camry, Corolla, RAV4, Tacoma), Honda (Accord, Civic, CR-V, Pilot), Nissan (Altima, Sentra, Rogue, Pathfinder), Hyundai (Elantra, Sonata, Tucson), and Kia (Forte, Sportage, Sorento) vehicle platforms spanning model years. Vehicle-specific fitment data includes steering ratio specifications, mounting bolt patterns, and hydraulic port configurations.
As a specialized steering gear supplier, we provide tie rod assembly wholesale programs featuring volume-based pricing: quantities 30-99 units receive distributor pricing, 100-249 units qualify for enhanced discounts, and 250+ unit orders access maximum volume pricing (35-55% reduction versus OEM retail). Global shipping available via ocean freight (FCL/LCL consolidation) and express air cargo to 95+ countries.
