The longer distance A is, the higher the spring preload; the shorter distance A is, the lower the spring preload. Spring preload setting*: Minimum (soft): 141.6 mm (5.57 in) Standard: 141.6 mm (5.57 in) Maximum (hard): 151.6 mm (5.97 in) * Distance A changes 1.5 mm (0.06 in) with each full turn of the adjusting nut. 3.
