Ski Alignment

WARNING! Improper ski alignment or adjustment may cause loss of steering 

control, resulting in serious injury or death. Do not attempt to change the ski 

alignment or camber adjustment. See your Polaris dealer.

With the handlebars in a straight-ahead position, and with vehicle 

weight compressing the suspension, measure from the straight edge of 

the skis at the center of the ski mounting bolt. The measurement 

between the skis at point X should be 1/8-1/4 inch (3-6 mm) greater than 

at point Y. 

Tip: If the skis are misaligned, we recommend that your dealer correct the align-

ment, since camber adjustment may also be affected.

Ski Skags

See your dealer’s studding chart for recommended skags. If you install 

longer or more aggressive carbide skags than the original equipment, it 

may also be necessary to add track studs to maintain proper vehicle con-

trol while turning on hard-packed snow or ice.

WARNING! Worn skis and/or skags will adversely affect handling. Loss of 

vehicle control may result, causing serious injury or death. Replace skags as 

recommended.

Check skags weekly to maintain positive steering characteristics. Skags 

must be replaced when worn to half their original diameter. Carbide 

skags must be replaced if any abnormal wear or chipping is found.

Skag Replacement

1. Raise and support the front of the machine so the skis are approxi-

mately 6I (15.2 cm) from the ground.

2. Remove the attaching hardware and pry the skag downward.
3. Remove the rear end of the skag.
4. Remove the front end of the skag.
5. Reverse the steps to install a skag.

Suspension Maintenance

Rail Slide Wear

For ease of inspection, all 

Polaris rail slides have a 

wear limit indicator groove 

to indicate the minimum per-

missible slide thickness. 

Replace the rail slides if they 

are worn to the top of the 

groove at any point along 

their length. Failure to do so 

may result in permanent 

damage to the track or rails.

Suspension Inspections

Loose nuts and bolts can reduce your snowmobile’s reliability and cause 

needless repairs and down time. Before beginning any snowmobile trip, 

a visual inspection will uncover potential problems. Check the follow-

ing items on a weekly basis or before any long trip:

n

Check suspension mounting bolts for tightness.

n

Check rear idler wheel bolts for tightness. See page 95.

n

Check rear idler adjusting bolt locknuts for tightness.

n

Check front torque arm limiter strap condition.

n

Check rail slide condition.

n

Check track tension. See page 94.

n

Lubricate/grease all suspension components. See page 70.

n

Check ski runner/skag condition. See page 99.

n

Check ski spindle bolts for tightness.

n

Check tie rod end nuts for tightness.

Replace when 

worn to top of 

groove
