THE PERFECT FIT
FAST M-10 Rear Suspension Adjustments
Static Sag and Ride Height Settings
FRA Position
The FRA setting is the primary rear suspension adjustment. It will have
the MOST effect on the rear suspension performance. To adjust the
FRA:
1. Refer to the initial set-up reference chart (located under the hood of
your snowmobile and on page 51) to determine the desired FRA
position.
2. To adjust, loosen the hex bolts (A) attaching the rear lower shock
cross shaft to the rail beam.
3. Using a 9/16” wrench, loosen the jam nuts (B) on the preload
bolts.
4. Adjust the preload bolts (C) to the desired FRA position.
5. Tighten the jam nuts. NOTE: Make sure the preload bolt contacts
the slide block before tightening the jam nut.
6. Tighten the hex bolts and torque to 35 ft. lbs. (47 Nm).
NOTE: If the M-10 suspension is new, it will take from 25 to 200
miles to properly break in the springs and shocks, at which time the
suspension will be softer and may require FRA readjustment.
