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 on page 47 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:
When the M-10 suspension is 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.
