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 53) to determine the desired FRA
position.
2. To adjust, loosen the hex bolts (1) attaching the rear lower shock
cross shaft to the rail beam.
3. Using a 9/16” wrench, loosen the jam nuts (2) on the preload bolts.
4. Adjust the preload bolts (3) to the desired FRA position.
5. Tighten the jam nuts.
NOTE: Make sure the preload bolt contacts the slide block before
tightening the j am nut.
6. Tighten the hex bolts and torque to 35 ft. lbs. (47 Nm).
NOTE: When the M-10 suspension i s new, it will take from 25 to 200
miles (40-300 km)to properly break in the springs and
shocks, at which time the suspension will be softer and may
require FRA re-adjustment.
