This 4-inch rear drop kit is engineered for trucks seeking a lowered stance while preserving drivability and suspension integrity. The flip kit repositions the axle above the leaf springs, achieving the drop. Rear hangers and shackles fine-tune the ride height and alignment. Bump stops protect the suspension from bottoming out, while shock extenders ensure proper shock travel. Sensor provisions are included to maintain compatibility with factory ride height sensors and electronic systems.
