Preload adjustment on FOX 2.5 coilovers factory race series.
Part#880-06-420 for Toyota Tundras 2000-2006 but should be similar for all FOX 2.5 Coilovers
From my search on forums 1/2” of preload roughly measures out to 1” of height increase. I increased the preload to 1 1/4” of preload roughly 2.5 inches of height increase.
