Traction Products

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.

Before equipping your snowmobile with traction products, be aware of regulations pertaining to the use of traction products in your area of operation.

Studs

Track damage resulting from improperly installed or maintained studs is not covered under warranty. Use only POLARIS-approved traction products on your snowmobile. See your dealer for more information about installing studs and/or carbides.

caution

Failure to heed the following recommendations will result in tunnel or track damage:

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.
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 inch (2.9 cm) from any edge of the track, including track window.
Studding the outside band of the track diminishes durability.
Polaris does not recommend studs on the outside band of the Storm 150 track. Damage will occur.

The AXYS Indy 129 chassis requires stud protection kit 2883572 to be installed before installing studs or chassis damage will occur. This stud protection kit will protect against chassis damage with the following track/stud combinations.

1.325” Polaris/Woody’s studs installed in a Ripsaw II 1.25” or Cobra 1.352” track .
1.575” Polaris/Woody’s studs installed in a Storm 150 track, center band only.

Penetration Range: 1/4-3/8 in. (6-9 mm)

Carbide Skags

A skag is a replaceable bar attached to the underside of the ski to assist in turning the snowmobile and to prevent ski wear caused by contact with roads and other bare terrain. Use carbide skags with studded tracks to help maintain proper steering and control. See Skag Replacement.

Maintain a proper balance between the number of studs and the length of carbide on the skags (the more studs you use, the longer the carbide on the skags should be). See your dealer's track studding chart.
