THE PERFECT FIT
FAST M-10 Rear Suspension Adjustments
Other Ride and Performance Settings
Overload Spring
The overload spring is located inside the main rear spring. Contact is
made with this spring only when the crossover tube comes in contact
with it toward the end of the travel, which reduces bottoming of the rear
suspension. The correct setting of the crossover tube length enables the
M-10 suspension to deliver superior performance in "bottoming" situa-
tions. This adjustment has no effect on spring pre-load or general ride
characteristics of the M-10 rear suspension, it affects only bottoming
resistance. To adjust the crossover tube length (dimension C in illustra-
tion and set-up chart):
1. Use the spanner wrenches located in the tool kit to unlock the upper
lock nut from the adjuster collar.
2. Turn the adjuster collar to the appropriate or desired dimension for
the rider's weight (refer to the initial set-up reference chart located
under the hood of your snowmobile and on page 51). Using the
spanner wrenches, tighten the upper lock nut firmly against the
adjuster collar.
