The link below is to a FAQ at Works Performance on suspension set-up. The setup for "sag" would be different on a stock HD shock but the principle is the same. You are looking for "sag" of 1 to 1.5 inches if you have standard length shocks. The link to the pdf file will explain measurements.Thomas Howard said:has anyone adj. the preload setting on the 06 Dyna rearshocks?
Does it help/hurt or even change the spring rate? how much?
