BYD Qin Pro， EV Rear Suspension Control Arm Assembly (L/R) | Multi-Link Rear Suspension Core Component OEM Spec

This product is specifically designed for the rear suspension system of the BYD Qin Pro EV (including pure electric and new energy versions). It is a core load-bearing component of the multi-link independent suspension connecting the rear wheel to the subframe—the rear suspension control arm assembly (also known as the rear lower control arm, rear suspension link, or trailing arm assembly). The rear control arm acts as the "skeletal joint" of the rear suspension system, firmly connecting the rear wheel to the vehicle body,承受ing longitudinal impact forces and lateral forces during driving, while cushioning road vibrations through rubber bushings. It is a critical chassis component for ensuring handling stability, ride comfort, and uniform tire wear.

The BYD Qin Pro EV features a MacPherson strut front suspension and multi-link independent rear suspension chassis structure, tuned by former Mercedes-Benz chassis expert Heinz Keck, balancing comfort and sporty handling. The rear suspension follows the classic Toyota "chopstick" suspension structure, consisting of three support arms. The Qin Pro EV replaced the aluminum alloy support arms of the older Qin 100 with lower-cost steel components, achieving cost optimization and a lower starting price. As a pure electric vehicle equipped with BYD's self-developed permanent magnet synchronous motor and ternary lithium battery pack, the Qin Pro EV has increased overall vehicle weight compared to the fuel version, placing higher demands on the load-bearing capacity of rear suspension components.

As a professional manufacturer of automotive chassis suspension parts, we develop and produce strictly according to BYD OEM technical standards, using high-strength alloy steel stamping, with key stress areas optimized through finite element analysis (FEA), and bushings featuring precision fit structures. The product passes rigorous dynamic fatigue tests, high-low temperature cycle tests, and salt spray tests, with OE numbers precisely matching the original vehicle for direct replacement of deformed, cracked, or bushing-aged original rear control arm assemblies.
