High-Precision OE Replacement: Engineered strictly to original factory specifications for Mercedes-Benz C-Class (W205) and E-Class (W213) electric power steering (EPS) systems. Direct replacement for OEM part numbers: A2054605202, A2054604501, A2054605400, A2134605301, A2134605302, and A2134606101.
Integrated Ball Screw and Nut Assembly: Features a pre-assembled, high-precision recirculating ball screw, nut, and bearing unit. Delivers ultra-low friction, zero backlash, and high mechanical transmission efficiency, effectively eliminating steering rack knocking noise and restoring crisp, responsive steering control.
Heavy-Duty 40Cr and GCr15 Alloy Steel: Manufactured from premium structural alloy steel with full CNC precision grinding. Rack teeth undergo medium-frequency induction quenching (HRC 58-62) to provide superior wear resistance, high fatigue strength, and extended service life under demanding road conditions.
Micro-Tolerance and Strict Quality Assurance: Produced in compliance with IATF 16949 quality standards. Each unit undergoes 100 percent dynamic balance testing, crack inspection, and runout verification (straightness tolerance within 0.01 mm) to ensure flawless alignment with electronic control units (ECU) and torque sensors.
Optimized for Remanufacturing and Wholesale Distribution: Designed specifically for professional steering gear rebuilders, repair workshops, and global auto parts importers. Backed by factory-direct pricing, flexible minimum order quantities, anti-rust oil coating, and export-grade heavy-duty packaging.
