Product Overview
Engineered for precision and durability, our aluminum steering knuckle is crafted using advanced investment casting technology to deliver unmatched strength-to-weight ratios, corrosion resistance, and reliability in automotive suspension systems. Designed for electric vehicles (EVs), performance cars, and off-road applications, this knuckle enhances handling, reduces unsprung weight, and ensures optimal alignment under extreme loads. As a leading investment casting foundry, we provide ISO-certified, customizable solutions tailored to meet global automotive standards.
Key Features
Lightweight Design: 40% lighter than steel, improving fuel efficiency and vehicle dynamics.
High Load Capacity: Reinforced geometry withstands vertical/horizontal forces up to 5,000 kg.
Corrosion Resistance: Ideal for harsh environments (road salt, moisture) with optional anodizing.
Precision Casting: Tight tolerances (±0.15mm) ensure exact suspension geometry and kingpin alignment.
Custom Integration: Compatible with MacPherson strut, double-wishbone, and multi-link suspensions.
