PRODUCT DESCRIPTION

Precision Hardened Steel Construction

This king pin OE 3001021-HA400 is manufactured to exact Dongfeng Dana axle original design specifications, using high-grade alloy steel that undergoes precision heat treatment and surface hardening for maximum strength and wear resistance. The product features precision-ground cylindrical surfaces that ensure a perfect fit with the axle knuckle bushings, minimizing friction and play for consistent steering response. Its robust design includes a factory-machined keyway to lock into the axle housing, preventing rotation and maintaining alignment under heavy loads. The 1:1 original dimensional design ensures seamless installation without modification, delivering reliable, long-lasting steering performance.

Steering Play & Premature Wear

Truck operators often face critical issues with substandard king pins, including excessive play caused by soft steel leading to loose steering and unstable handling; poor surface finish causing rapid bushing wear and premature failure; and mis-machined dimensions leading to fitment issues and axle damage. A faulty king pin compromises vehicle control, creates safety hazards and increases maintenance costs. By choosing the genuine OE 3001021-HA400 king pin, users can instantly resolve these problems, ensuring tight steering response and extended axle component life.

OEM Quality & Rigorous Durability Testing

As a key steering and axle component for heavy-duty trucks, this king pin assembly complies with Q/DFL 6020-2021 Dongfeng automotive parts quality standards and has passed comprehensive third-party tests for hardness, fatigue resistance and dimensional accuracy. Test data shows the king pin maintains dimensional integrity under heavy axle loads, withstands repeated steering cycles without wear, and meets all applicable axle performance specifications. Each unit undergoes 100% dimensional inspection, hardness testing and surface quality verification before leaving the factory, guaranteeing complete consistency with original factory parts in performance, durability and fit. Backed by official factory traceability codes, this product ensures 100% authenticity and long-term trouble-free operation.
