Wishbones & Control Arms

Wishbone and control arm assemblies connect the wheel hub to the chassis and define the wheel's arc of travel during suspension compression and rebound. Worn or bent control arms on BYD EVs cause accelerated tyre wear, steering pull, and ADAS camera misalignment that can trigger calibration faults. This category covers front lower control arms, rear upper and lower arm assemblies, swing arm bushing assemblies, traction arm assemblies, suspension guide arms, and control arm ball joint assemblies for BYD Atto 3, Dolphin, Sealion 7, and Denza D9. Replacement units must meet the original hardness and geometry specifications to restore factory handling characteristics and alignment settings.
