THE PERFECT FIT
M-10 Suspension
Rear Suspension Setup
1. Adjusting the Full Range Adjuster (F.R.A.)
1. Refer to the initial set-up reference chart (located under the hood of
your snowmobile and on page 64) to determine the desired F.R.A.
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 F.R.A. position.
5. Tighten the jam nuts (B). NOTE: Make certain the preload bolt is
contacting the slide block before tightening the jam nut.
6. Tighten the hex bolts (A) and torque to 35 ft. lbs.
NOTE: The FRA setting is the primary rear suspension adjustment. It
will have the MOST effect on the rear suspension performance.
If the M-10 is new, it will take anywhere from 25 to 200 miles to
properly break in the springs and shocks. At the time of break-in, the
suspension will get softer and may require the FRA to be re-adjusted
