Optional S pring Rates - Optional springs have been designed to allow
adaptation of the M10 to the varied needs of our customers. The 140
lb./in. option front arm spring would be used when very light loads are
encountered such as very smooth trails, deep powder or by very light
riders.

Preload - Is basically the pre-tensioning of a spring by installing it on
a shock at less than its free length. Free Length - Installed Length =
Inches of PRELOAD OR 10.5″ -9.75″ =.75″ of PRELOAD
Dual Rate - Refers to 2 different SPR ING RATES designed into one
spring. Notice that M10 coil springs are often “dual rate” having a soft
(closely wound) area and a firm (loosely wound) area.
Overload Spring - Located inside the main rear spring, contact is
made with this spring only when the X-OVER tube comes i n contact
with it towards the end of the travel, reducing bottoming of the rear
suspension.
X-OVER or CROSS OVER - Describes the transition from one
spring rate to another. During compression travel, t he space between
the closely wound coils eventually disappears. At this point, t he spring
“CROSSES OVER” from the soft to the firm rate. This term also
includes the transition that occurs when the overload spring is engaged
by the “X-Over Tube” on the rear shock.
