Setting sag ensures that you are starting with the proper spring
rate. In coil-over applications, we like to see 30–35 percent of the
shock stroke be taken up in sag.
This shock is 8. 5 inches eye to eye, with 2. 5 inches of stroke, so it
should have about . 75 inches of sag.
Coil shocks are fitted with an adjustable preload spring retainer on one end. This can be used to add up to two full turns of
preload in order to fine-tune the initial ride height of the bike.
Start by turning the collar to where it just holds the spring in
place without rattling, then turn the collar clockwise to
increase the preload. Do not exceed two full turns, as it may
cause damage to the shock and/or spring. If more than two
turns are required, you’ll need to swap for a stiffer spring.
Using a flat surface, sit on your bike in a normal riding
position wearing your riding gear, including hydration
pack. Be sure to bounce on the suspension a couple of
times to ensure that any initial shock or suspension linkage friction is broken. Using a tape measure, measure
the distance from center to center of the shock mounting bolts. If sag is excessive, a stiffer spring would be
recommended. If sag is not enough, a softer spring is
