Preload is the amount of pressure applied to the spring eye while the car is sitting on the ground at rest. The recommended preload is 11/42 inch between the pinion snubber and the leaf eye. Adding more gap adds more inertia and therefore more smack on the tire. Ours worked best with zero gap, which can be adjusted by lowering the bar with a shim between the spring and the bar at the baseplate.
