BYD Qin PLUS DM-i Front Subframe Assembly | Chassis Load-Bearing Structure OEM Spec

This product is specifically designed for the front chassis system of the BYD Qin PLUS DM-i. It is a core load-bearing structural component located beneath the engine, connecting the body to the suspension system—the front subframe assembly. Named for its resemblance to the traditional Chinese "Yuanbao" (ingot), the front subframe is a critical component of the chassis system, serving multiple functions: supporting the engine and transmission, carrying the suspension and steering systems, absorbing road impact loads, and enhancing overall vehicle rigidity and stability.

The BYD Qin PLUS DM-i features a non-full-frame front subframe design. The front suspension is a MacPherson independent suspension, with key components such as the lower control arm and steering tie rod made of steel. The subframe is connected to the body via raised brackets to create space for the battery pack. In terms of suspension, the front suspension uses a MacPherson independent setup, with both the lower control arm and steering tie rod made of steel. The lower control arm ball joint features a separate design for convenient future replacement. As a professional manufacturer of automotive chassis structural parts, we develop and produce strictly according to BYD OEM technical standards. Using high-strength steel stamping and welding, with key stress areas optimized through finite element analysis (FEA) and an e-coat anti-corrosion finish, the product passes rigorous salt spray tests and dimensional accuracy inspections. The mounting holes are 100% precisely matched with the original vehicle for direct replacement of accident-damaged or severely corroded original subframe assemblies, restoring chassis structural rigidity and driving stability.
