This modification involves relocating the spring hangers from the top to the bottom of the leaf springs and repositioning the shackles to the opposite end. It’s a suspension alteration often implemented on a specific model year of a heavy-duty Ford truck to achieve improved ride quality and potentially greater suspension articulation. This is accomplished by changing the geometry of the front suspension system.
The primary advantages often cited for this modification include a smoother ride, especially on rough terrain, and potentially increased off-road capability due to enhanced suspension travel. Historically, this type of modification gained popularity as a means to address the perceived stiffness of the factory suspension on these trucks, offering a more comfortable driving experience for both on and off-road use. The change in suspension geometry can influence handling characteristics and overall vehicle stability.
