The upside-down strut design provides superior lateral force support and precise wheel guidance during acceleration, braking, and cornering. Height adjustability allows you to dial in your preferred stance while maintaining proper suspension geometry. The robust trapezoidal threads remain adjustable even after extended use, ensuring long-term reliability.
