- Maintaining Tire Contact: By controlling vertical wheel movement, they help keep tires in consistent contact with the road surface, which is crucial for steering, braking, and acceleration.
Properly functioning MOOG coil springs contribute to stable handling and a comfortable driving experience, ensuring the vehicle's suspension system operates as intended.
