Material & Manufacturing Technology
The ball pin and shell 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, not easy to form loose clearance on bumpy roads.
Precision processing strictly follows OE dimension 3640.53 for perfect fitting. Zinc-plated surface provides excellent anti-rust performance. High-quality rubber dust boot stops sediment and muddy water entering inside. Pre-filled high-temperature grease ensures flexible movement.
