Material & Manufacturing Technology
The control arm body and ball joint adopt high-quality 40Cr alloy steel, integrally forged, quenched and tempered with high-frequency surface hardening treatment. High hardness, outstanding wear resistance and impact resistance, hard to produce loose clearance when driving on bumpy roads.
Precision production strictly follows OE dimension 3520.L8. Zinc-plated silver surface provides excellent anti-rust property. Equipped with high-performance rubber bushing and dust boot to prevent sediment and muddy water entering inside. Pre-filled high-temperature long-life grease guarantees flexible swing.
