In high-performance custom trucks, achieving neutral handling requires a counterintuitive setup: deliberate chassis asymmetry. Due to the driver's weight and the typical crown of the road, the left-side spring rates and sway bar preload are often increased by 5-10% over the right side. This compensates for weight transfer during right-hand turns (the most common turn direction on roads). A technical breakdown of how to calculate and tune this asymmetry using adjustable coil-overs and sway...
