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. The addition of carbide skags is
recommended with studded tracks to help maintain proper vehicle
steering and control. Similarly, if your machine is equipped with
carbide skags or if you're adding them, it may be necessary to add
track studs to maintain proper vehicle control. Proper balance must be
maintained between the number of studs and the length of the carbide
on skags. The more studs used, the longer the carbide on the skags
should be. See your dealer's track studding chart for recommended
studding and skags.
Inspect skags and studs frequently. Worn studs or skags may reduce
steering and braking control on hard-packed snow and ice. Replace
worn studs and skags to maintain proper balance and vehicle control.
When studded tracks are used, increased wear to the brake pads will
result from increased braking. Extended-wear brake pad kits are
available. See your dealer for more information.
Aggressive studding patterns may require that you grind protruding
stud bolts flush to prevent idler wheel damage. Maintain track
tension on studded tracks on the tight side of the spec to prevent
heat exchanger damage. Center of stud must be at least 1 1/8"
(2.86 cm) from the outside edge of the track.
Use only Polaris traction products on your snowmobile. Track
warranties are void if track damage or failure results from improper or
excessive stud installation or the use of non-Polaris traction products.
