The Fabtech upper control arm component for 2025 GM 1500 (2WD/4WD) uses an arc spring spacer kit to achieve a 3-inch lift while integrating with the truck’s suspension geometry. This lift component set is intended to preserve suspension articulation and ride quality by working with existing hardware, offering a practical approach to gain clearance without extensive modification to the factory coilover arrangement.
