Studs
Failure to heed the following recommendations will result in tunnel or track damage and a voided warranty.
The track is not warranted by POLARIS if studs have been installed. Track warranties are also void if track damage or failure results from the use of any non-POLARIS traction products. Use only POLARIS-approved traction products on your snowmobile. See your dealer for more information about installing studs and/or carbides.
Use of studs longer than the recommended length on snowmobiles equipped with center coolers will result in center cooler damage or damage to the tunnel.

Track Studding
Track studding will enhance braking control on hard-packed snow or ice, but extreme caution is still required on such surfaces. Steering ability may be reduced on hard-packed snow or ice.
When studded tracks are used, increased wear to the brake pads will result from increased braking and requires increased brake inspection intervals.
Installing studs can also cause the track to stretch more than a non-studded track. For this reason, POLARIS recommends inspecting track tension more often and setting the tension at the preferred measurement.
Always adhere to the manufacturer’s stud maintenance procedures and stud nut torque specifications.
Aggressive studding patterns may require grinding protruding stud bolts flush to prevent idler wheel damage. Maintain track tension on studded tracks on the tight side of the specification to prevent heat exchanger damage. The center of the stud must be at least 1 1/8 in (2.9 cm) from the outside edge of the track.
Before equipping your snowmobile with traction products, be aware of regulations pertaining to the use of traction products in your area of operation.
