This product is specifically designed for the front suspension system of the BYD Qin PLUS DM-i. It is the core structural component connecting the wheel to the vehicle body suspension system—the front knuckle (also known as the steering knuckle). The knuckle is a critical component in the vehicle's steering axle, responsible for transmitting and bearing the front load, supporting and driving the front wheel to rotate around the kingpin for steering, while also providing mounting points for components such as wheel bearings, brake calipers, suspension control arms, and steering tie rods. It is one of the most stressed and precision-demanding core components in the front suspension system.

The BYD Qin PLUS DM-i features a classic MacPherson strut front suspension. The front suspension is MacPherson independent, with lower control arm links and steering tie rods made of steel, and the lower control arm ball joints are designed as separate replaceable components, allowing for replacement when worn or aged. The Qin PLUS features a front MacPherson independent suspension + rear torsion beam non-independent suspension combination. The knuckle works in precision coordination with multiple components including the lower control arm ball joint, stabilizer link, strut assembly, wheel hub bearing, and brake caliper, collectively ensuring precise handling and driving stability.

As a professional manufacturer of automotive chassis suspension parts, we develop and produce strictly according to BYD OEM technical standards. Using high-strength ductile iron (QT450-10) material through precision casting, critical areas are CNC machined for precision. The product features excellent impact resistance and dimensional stability, adapting to all Qin PLUS DM-i 2021-present models. The mounting holes are 100% precisely matched with the original vehicle for direct replacement of damaged or deformed original knuckles, making it an ideal choice for aftermarket repair, accident vehicle restoration, and chassis overhaul.
